Astm A, Aisi S5. Your recently viewed items and featured recommendations. For best machining, it is often used in the annealed condition; however, when the amount of machining necessary is minimal or when the risk of distortion in heat treating a a322 part is paramount, it is typically used in the quenched and tempered condition.

The nickel content contributes to case toughness at high strength with above average core toughness. Hot-wrought alloy steel bars are produced in cut lengths and coils; the manufacturer should be consulted regarding sections and sizes available in coils, produced to a chemical composition. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. There are several production and finishing options available for each type, including polished and hot rolled steel rod.


Typical applications for hot rolled bar include gears, pinions, shafts, and other applications where it is helpful to have a steel that can be readily machined and carburized to controlled case depths. This medium carbon, chromium-molybdenum, through-hardening alloy steel has a good hardenability with high strength and toughness as well as good fatigue and impact resistance after heat treating.
