Alloy Steel.jpg

Alloy Steel

Alloy Steels have additional alloying elements such as vanadium, chromium, and nickel, which are in quantities greater than other accepted resident interstitial elements. These may be formulated for greater strength, better toughness, higher hardenability, or any combination of these. 

​

They are usually employed in demanding, high-wear roles that also require greater strength, such as driveshafts, axles, crankshafts, and gearsets.

​

Integ Metals supplies 28 different grades of alloy steel, so please contact us to place an order with your specific requirements, or read on for more information.
