The latest knowledge of bearing in jiaxing bearing: about bearing steel heat treatment several common concepts

There is rotational, have HRB bearing ( ) Get the latest bearing information, learn more knowledge of jiaxing bearing, to company, sincere service, the choice of wisdom. Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Today follow the author to learn: about bearing steel heat treatment several common concepts. Is fire, the steel or steel heated to a critical point AC3 or ACM more appropriate temperature keeping time, cooled in the air after get pearlite bearing steel heat treatment process of the organization. Annealing annealing: hypoeutectoid steel workpiece heating to AC3 above 2040 degrees, insulation after a period of time, with the slow cooling furnace ( Buried in the sand or lime in cooling) Limitation: alloy solid solution bearing steel after heat treatment or cold plastic deformation at room temperature or slightly higher than room temperature keeping, the phenomenon of its performance change with time. Steel carbonitriding: carbonitriding is to steel surface infiltration process of carbon and nitrogen at the same time. Traditionally carbonitriding, also known as cyanide, is currently in medium temperature gas carbonitriding and low temperature gas carbonitriding ( The gas soft nitriding) Are more widely application. Medium temperature gas carbonitriding's main purpose is to improve the steel hardness, wear resistance and fatigue strength. Low temperature gas carbonitriding with nitriding is given priority to, its main purpose is to improve the wear resistance of steel and resistance to bite. Tempering treatment quenchingandtempering: general habit to combined bearing steel of high temperature quenching and tempering heat treatment known as conditioning treatment. Conditioning treatment is widely used in various important structural parts, especially those who work under alternating load of connecting rod, bolts, gears and shaft, etc. Conditioning treatment after get tempered sorbite organization, its mechanical performance than the same hardness of normalizing sorbite for optimal organization. It depends on the high temperature tempering temperature and hardness and tempering stability of steel and the workpiece with the size of section, generally between HB200350. Brazing: the two kinds of artifacts together with solder bearing steel heat treatment process.
