lysn-bearing

lysn-bearing steel quenched martensite by the quenching , a small amount of undissolved carbides and the second about 12 % to 14 % of residual austenite . Quenched martensite and residual austenite is stable organization during tempering martensite decomposition volume contraction of the steel , and the decomposition of the residual austenite volume swell of the steel .As the tempering temperature increased, the amount of decomposition of the residual austenite increases , the hardness required to ensure the process conditions, Slewing Bearing an appropriate increase in the tempering temperature , the residual austenite decomposition into the larger specific volume of martensite organizations can work volume increases accordingly
