At Associated Steel, we pride ourselves on offering an in-depth selection of alloy and carbon steels. These materials include hot roll heat treated, cold finished annealed, turned ground and polished, heat treated hollow stock, induction hardened linear shafting, pre-keyed shafting, keystock, and custom manufactured wear “rails”.
Alloy Steels
KROMITE® #3 4140/4150 (modified) Hot Roll, Heat Treated, High Strength Alloy
It is offered in the hot roll, heat treated condition. Typical hardness is Rockwell “C” 28/34. Typical tensile strength 156,000 PSI. This proprietary product provides elevated strength and deep uniform hardness, excellent cleanliness, and refinement to the grain structure to enhance the fatigue resistance of the steel. Good choice of steel for machined parts requiring higher resistance to toughness and general impact resistance.
