以锡代铅研制环保型易切削钢

Development of Non-leaded Free-Cutting Steel by Adding Tin

摘要: 以锡代铅研制了一种含锡的环保型易切削钢,并进行了切削及力学性能试验.结果表明,在含量小于0.05%(质量分数)时,锡能明显改善钢的易切削性能,未发现对钢的力学性能有不利的影响.

Abstract: A type of non-leaded free cutting steel was developed by adding tin into 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.
