低淬透性钢是将含碳量为0.005～0.007左右的优质碳素钢中的锰、硅含量降低,改变脱氧工艺,并加入少量钛作为变质剂,以细化晶粒,消除硫等杂质的影响而形成的。它的强度高,淬透性低。实质上是用热处理的方法使普通优质碳素钢升级成为制造重载齿轮的钢材。用它制造大、中模数齿轮时,应采用中频淬火以水为冷却剂;制造小模数齿轮则宜 Low hardenability steel is the carbon content of about 0.005 to 0.007 quality carbon steel manganese, silicon content decreased, change the deoxidation process, and add a small amount of titanium as a modifier to refine the grain, eliminating sulfur and other impurities The formation of the impact of. Its high strength, low hardenability. In essence, heat treatment is used to upgrade ordinary high-quality carbon steel to heavy-duty steel. Use it to manufacture large and medium modulus gear, you should use IF quenching with water as coolant; manufacturing small modulus gear is appropriate
