Made of a chromium-nickel-molybdenum alloy and strengthened with vanadium, this steel is the strongest alloy we offer. A vacuum arc remelting (VAR) process gives 4330 alloy steel excellent strength, hardness, and fatigue resistance. It also resists cracking from impact or compression. In addition to the VAR, this steel's been normalized—a form of heat treatment that helps yield consistent results if you want to machine or heat treat it further. More heat treatment will make the surface harder and more wear resistant. These rods and discs are often used for gears, axles, and shafts. They have been manufactured to meet AMS standards for quality and performance.
