Nickel Alloy 625 bar, rod, and wire is used for its high strength, easy fabrication (including joining), and outstanding corrosion resistance. Service temperatures range from cryogenic to 1800?F (982?C). Alloy 625 derives its strength from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix thus eliminating the need for precipitation-hardening treatments. This unique composition is also responsible for the products superior resistance to a wide range of severely corrosive condition and high-temperature effect such as oxidation and carburization. The properties of Alloy 625 make it an excellent choice for seawater, aerospace, and chemicalprocessing applications.
Inconel 625 is a nickel-base alloy used both for its high strength and outstanding aqueous corrosion resistance.

Upgrades. They seem to be a pervasive part of 21st Century life. While flying in First Class is certainly nice, its a trade off of personal comfort against a somewhat stiffer fare. There are also upgrades for connecting rods but instead of wine with cheese you get that added insurance of a better connecting rod bolt that that offers added peace of mind for that spinning big-block at full song. When you consider the consequences of an expired engine, the tradeoff is well worth the expense.
The BoostLine connecting rods come standard with the ARP 2000 rod bolt that is already a strength improvement over ARPs industry standard 8740 chrome moly fastener. Now for sport compact applications. They are now offering a 625 Plus upgrade.
Sure, you can look up the numbers on the included chart and see that as the material quality improves, the bolts get stronger. But what do these numbers mean? Lets dig a little deeper and come up with some answers.
We cant emphasize enough the fact that a connecting rod bolt is the most highly stressed component in an internal combustion engine. The usual talk about connecting rods centers on how the rod can stand up to the compressive cylinder pressure loads of a boosted engine. While this is an important point, its usually where the strength discussion ends. I-beams (or H-beams) have been used since ancient times to support compressive loads. The opposite of compressive loads are what are termed tensile loads. This is defined as the ability of a material to withstand a pulling force. In the case of a connecting rod, this pulling force focuses directly on the connecting rod bolts.
So this means the connecting rod is exposed to forces or loads in both compressive and tensile directions. The highest tensile loads occur when the crankshaft yanks on the piston through the connecting rod downward across TDC during the overlap cycle. This doesnt sound all that bad until we add the variable of rpm where the cycling of compressive and tensile loads occurs very quickly. At 7,000 rpm, the piston completes one revolution 116 times, changing direction twice.
This cycles the rod with incredibly high loads in both directions. We will focus on the tensile loads here because much of that pulling force is concentrated on the rod cap and therefore the connecting rod bolts since these fasteners are the only things preventing the rod from coming apart.
Its also important to mention that while connecting rods are often rated using horsepower as an arbiter of strength, engine RPM and weight are two other major considerations. Weight and strength are often considered to be mutually beneficial but when it comes to connecting rods, lighter is better as long as strength is not compromised. As the piston crosses top dead center (TDC) and the crankshaft begins to move the piston downward, it is simultaneously attempting to pry the rod cap right off the rod.
The rod bolts are the only things holding all this together. Tensile load is directly related to both mass and RPM. The g-forces that create this tensile load can be enormous. At 10,000 rpm a typical NASCAR Cup engine can experience a g-force load of over 5,800 gs at TDC overlap. Given a typical weight of 850 grams for the piston and rod, this would put the tensile or stretching load on the connecting rod at nearly 11,000 pounds of force. Thats 11,000 pounds attempting to stretch the connecting rod bolts.
It isnt overstating the case in the least to say that extreme RPM places extreme load on the rod bolts while they simultaneously attempt to maintain big end concentricity. In the case of a 3.75-inch stroke small-block Chevy with a relatively light reciprocating package of piston and rod, at 7,000 rpm, the cap end of the rod could easily be stressed with over 7,100 pounds of tensile load. Just raise the rpm to 7,500 and the load jumps to over 8,200 pounds of force. Split that between two rod bolts and youre looking at over 4,000 pounds of force that is attempting to rip the cap off the end of the rod.
These numbers are not fabrications. We spoke with ARPs Chris Brown who plugged these numbers into a proprietary program the company uses to accurately estimate connecting rod bolt fastener load values. The RPM has a massive effect on rod bolt load. The load goes up as a square with rpm, so even a small increase in rpm results in a huge load increase. The numbers dont lie.
All of this is taken into account when the engineers designed the BoostLine rod and why they offer not only the ARP 2000 bolt as standard but also with an upgrade to ARPs Custom Age 625 Plus rod bolt.
As you can see from the accompanying chart, while the ARP 2000 bolt offers outstanding tensile load characteristics, it is possible to improve upon these specs with the Custom Age 625 Plus bolt. Note that while the 625 Plus bolts absolute tensile strength does increase slightly, the yield strength is significantly greater. This allows a greater clamping load to be applied to the bolt in order to maintain big-end concentricity.
But it gets better. The common misconception is that higher tensile strength automatically means the bolt is now more brittle. While that is true of some materials and heat treatments, certain materials, like Custom Age 625 Plus actually offer improvements in both tensile strength and ductility.
According to Brown, Custom Age 625 Plus is a cold-worked alloy whose characteristics deliver not only a higher ultimate tensile strength, but do so with equal or better ductility. This is important because there are bending moments that occur at the parting line of the connecting rod that make the rod bolts ductility an important safety factor. Thats the advantage Custom Age 625 Plus bolt offers.
Choosing this bolt also means a significant change to the validation process for the connecting rod. With a greater clamp load applied with the better bolt, this means that the stretch factor is also different, something that must be strictly adhered to both when checking bearing clearances and during final assembly.
All the above reasons are why it is critical that these rods be assembled with a rod bolt stretch gauge. The process is not difficult although it does require a bit more effort compared to merely torquing bolts. Do not be tempted to take the shortcut of measuring the torque required to stretch one bolt and apply that figure to the remaining bolts. Each bolt must be individually checked for stretch and each fasteners relaxed length should also be measured and recorded. This way, the bolt can be quickly evaluated after disassembly.
BoostLine offers the ARP Custom Age 625 Plus bolt as a regular option to all sport compact applications that can be ordered simply by adding the + sign after the appropriate standard BoostLine rod part number.
The combination of an incredibly strong rod with an equally high yield strength offers that safety margin that is necessary when pushing the performance limits of any engine. The combination of the BoostLine rod and ARP Custom Age 625 Plus bolt delivers exactly that kind of reciprocating peace of mind.

Inconel 625 is a nickel-chromium alloy that is used for its high strength, excellent fabricability, and outstanding corrosion resistance. The strength of Inconel 625 comes from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix.
This combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.
Inconel 625 is used primarily in four applications: seawater, aerospace, chemical processing, and nuclear. Inconel 625 is a great choice for seawater applications because of its high corrosion-fatigue strength, high tensile strength, and its resistance to chloride-ion stress-corrosion cracking.

Inconel 625 is a Nickel-Chromium-Molybdenum-Columbium (Niobium) alloy with excellent oxidation resistance, corrosion resistance, and strength at high temperatures. Age-hardening treatments are not required to obtain the high strength properties of Inconel 625 due to the solid solution effects of molybdenum and columbium on the nickel-chromium matrix. Inconel 625 is resistant to chloride-ion stress-corrosion cracking, pitting, and stress-corrosion cracking making it suitable for seawater applications. Inconel 625 can operate from cryogenic temperatures up to 1800F (980C).
Inconel 625 wire alloy can be made in flat, square, or even shaped wires. When you begin to analyze it, the two things that immediately stand out are its resistance to oxidation and its scaling at very high temperatures. This makes it vastly superior to other alloys, even ones that are made for high temperatures and varying heating and cooling conditions. The makeup of Inconel 625 wire also makes it able to withstand corrosive environments as well, even severe ones. In fact, there is almost no impact on the wire in fresh or even salt water. This also holds true for non-acidic environments as well. The high levels of Molybdenum also allows the alloy to be very resistant to pitting.
Further analysis into the Inconel 625 wire alloy shows that the aversion to corrosion and oxidation is due to the presence of Niobium, or more specifically the way the Molybdenum reacts with the Nickel contained within the wire. The Niobium also provides for strength and toughness, which means that it can be relied upon to function in extreme conditions. The alloy has a good fatigue strength and stress-corrosion cracking resistance to chloride ions, which is why oxidation and corrosion is so rare. 625 is also flexible, both in its side to side mobility, and the variety of places that it can be used.
The main application you will see Inconel 625 wire alloy being used in is marine environments. The salt level contained in ocean and sea waters normally has a horrific effect on any metal that spends a long period of time in it. However, this alloy can withstand the damaging effects, so it makes it an ideal wire for any machine used underwater. However, there are places that you may not think of that are also beneficial for Inconel 625 wire. For example, the two properties of steam that most people are aware of is that it is the gaseous state of water, and that it is very hot. Therefore, any machine that uses steam could be damaged by either extreme heat, or natural corrosion that comes from water. As this is the environment that 625 thrives in, you will see it used in things like exhaust systems, ducting systems, engines, and chemical processing equipment.
Inconel 625 wire is able to withstand these wicked environments because of the way that it was designed. It was specifically made for steam-line piping, but has morphed some over the years. Now, it will hold true at low and high temperatures, and is extremely resistant to creep properties, which is its true strength other than anti-corrosion. Creep conditions happen when high temperatures are met with applied stress. However, Niobium, the chemical alloy that makes up 625 wiring, prohibits creeping, which can be very detrimental to any wiring.
