Angular contact ball bearing precipitation hardening stainless steel types

With the continuous improvement of industrial level, the bearings used on some equipment are required to have good corrosion resistance and certain mechanical strength. Ordinary alloy materials can no longer meet the production requirements of precision bearings, and need to be replaced by heat-resistant high-strength materials. Therefore, precipitation hardened stainless steel materials have been developed and applied. Then the following Zhongda Xiaobian will introduce you to the types of precision bearing precipitation hardened stainless steel heat.
Martensitic type: Martensitic precipitation hardening stainless steel can be divided into martensitic precipitation hardening type and martensitic aging hardening type. However, the supply state of various martensitic precipitation hardening stainless steels is martensite, and crystal formation can achieve precipitation hardening effect with simple aging treatment.
Semi-austenitic type: Semi-austenitic precipitation hardening stainless steel, the supply state is austenite. This type of steel must be transformed into martensite through special heat treatment before precipitation hardening treatment.
Austenitic type: Austenitic precipitation hardening stainless steel is supplied in austenitic state and can be directly precipitation hardened.
