Suggested treatment
Higher strength and lower deformability than 1016. Used under conditions where surface hardening is required, but the center strength is not critical.
Large section shafts that do not suffer from heavy loads. Springs with high wear resistance, hardened pins and chains and automotive wheel rims (special profiles).
Cementation at 915 ° C for 8h, reheating at 790 ° C and quenching in water. Tempering at 175 ° C. [RT (521Mpa), LE (302MPa), A (31.3%) and D (156H)].
