Seamless steel tubes for gears

It is suitable for machining materials of gears and tooth shafts in automobile industry.

Gear steel usually offers good strength, hardness and toughness after heat treatment according to the requirements of usage, or the surface is wear-resistant and the core has good toughness and impact resistance. Germany adopts Mn-Cr series and CR-Mn-B series L (16MnCr5, 20MnCr5, 25MnCr5, 28MnCr5, ZF6, ZF7, ZF7B); Japan adopts Cr series and CR-Mo series (SCr420H, SCM415H, SCM420H, SCM822H); the United States adopts Cr-Ni-Mo series (SAE8617H, SAE8620H); France adopts Cr-Ni series (195) and CR-Mo series (20CD4, 20CD4, SAE8620H); 27CD4, 30CD4) steel; 20CrMnTi gear steel is widely used in China
