【Abstract】 A type of non-leaded free cutting steel was developed by adding tin into the steel melt. Machining tests and mechanical tests of the steel were conducted. The results showed that tin would improve the machinability of the steel when the tin content in the steel was less than 0.05%, and any negative influence was not found on the mechanical properties of the steel.更多还原
