Abstract

The invention discloses wear-resisting antioxidant alloy spring steel and a heat treatment process thereof. The spring steel comprises 0.360-0.550% of C, 0.260-0.450 % of Cu, 0.150-2.20% of Mn, 0.800-5.420% of Si, 0.700-3.800% of Cr, 0.030-0.080% of P, 0.030-0.050% of S, 0.300-0.500% of Ni, 0.008-0.050% of Al, 0.020-0.100% of V, and the balance Fe and inevitable impurities. According to the heat treatment process, the tempering temperature is 750+ / -10 DEG C, the temperature holding time is 6-8 h, and then air cooling is carried out; and the quenching temperature is 800-830 DEG C, the temperature holding time is 80-150 min, and then water cooling is carried out. Through the heat treatment process, the excellent wear-resisting antioxidant properties of the wear-resisting antioxidant alloy spring steel are realized, consumption of materials is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an alloy spring steel, in particular to a wear-resistant and anti-oxidation alloy spring steel and its heat treatment process. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Spring is an important component of mechanization and automation, and is widely used in aerospace, machinery manufacturing, transportation, instrumentation and other industries, and is generally made of spring steel. [0003] According to the GB / T standard, spring steel is divided into non-alloy spring steel (carbon spring steel) and alloy spring steel according to its chemical composition. Among them, alloy spring steel has a wide application prospect because the addition of alloy elements significantly improves the relaxation resistance...
