View Sample Alloy Digest Data Sheet (PDF)

Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.

AISI 5155 is a low-alloy, through-hardening steel containing nominally 0.80% chromium. It is recommended for uses where medium harden-ability, moderate strength and low-to-moderate toughness are satisfactory. It is normally used in the oil quenched-and-tempered condition; however, it also may be used in the unhardened (annealed, as-rolled or normalized) condition. Its applications include gears, springs, wrenches and machine tool parts.
