spring steel GB/T 1222 65MN spring washer hardness: 240~270HB
1. Brief Introduction
65Mn steel is a Chinese GB standard spring steel grade. Its strength, hardness, elasticity and hardenability are higher than that of 65# steel, but it has superheat sensitivity, easy to produce quench crack and temper brittleness. The annealed state has good machinability, and the cold deformation plasticity is low, but the weldability is poor.
65Mn high carbon steel is mainly used in the manufacture of various small-section flat springs, round springs, clockwork, etc. It can also be used to manufacture spring rings, valve springs, shock absorbers, clutch reeds and brake springs.

2. 65Mn Spring Steel Equivalent
65Mn steel is considered to be equivalent to AISI/SAE 1065, and some people also compare 65Mn with AISI/SAE 1075, 1095, 5160; JIS SK5 (SK85) and Chinese 8Cr13Mov, so the table below lists the difference of chemical composition for your reference.
