摘要
我国自从引进开发SCM822H钢种以来,其窄淬透带有效的稳定与控制问题,一直严重地困扰钢材用户和生产厂家。影响淬透值的因素有多种,找出其作用机理和控制方法是本文探讨的重点。
The SCM822H is one kind of high-quality gear steel.Chiefly served as to manufacture the rear axle level gear of heave-duty truck.Introducing it from elsewhere afterwards,Heave-duty truck of our country entirety is manufacture the level and was possess the very great raise.Since the fact that narrowly harden ability characteristic in that steel brings puzzling of manufacture technique,The manufacturing cost is so taller that the companies can not to content consumer.In order to meet consumer＇s necessaries,Have to find out its technique essentials.
