高碳铬轴承钢贝氏体淬火能显著提高钢的强韧性、比例极限、屈服强度和断面收缩率;与相同温度回火的M组织相比有更好的耐磨性;尺寸稳定性好;可以实现无裂纹淬火等一系列优点,所以广泛应用在轧机轴承和铁路轴承上。介绍了国内外对贝氏体淬火工艺的研究和应用情况。
High-carbon chromium bearing steel bainite quenching can significantly improve the strength and toughness of steel, the ratio of limit, yield strength and reduction of area; with the same temperature tempering M organization has better wear resistance; good dimensional stability; Can achieve a series of advantages such as crack-free quenching, so widely used in rolling mill bearings and railway bearings. The research and application of bainite quenching technology at home and abroad are introduced.
