日本高强度齿轮钢的现状,最显著的特点:①采用提高压缩残余应力的方法,来提高耐疲劳强度的性能。②降低Si等元素含量,减少渗碳时的内部氧化。③合金成份的设计喷丸处理相结合,以提高齿轮的强度。下面介绍日本六家钢铁厂生产的高强度齿轮钢的情
The status quo of Japan’s high-strength gear steel, the most significant features: ① to improve the compressive residual stress method to improve the fatigue resistance of the performance. ② reduce Si and other elements to reduce the internal oxidation carburizing. ③ alloy design shot peening combined to improve gear strength. The following describes the situation of six high-strength gear steel produced by Japan’s six steel mills
