国外最近研制成功一种新型易切削不锈钢。它的结构为铁素体,而且抗腐蚀性能也很好。加工时所允许的切削速度比普通不锈钢高2～3倍。试验表明,加工这种钢比加工普通不锈钢生产效率提高了一倍。
Foreign recently successfully developed a new type of cutting stainless steel. Its structure is ferrite, and corrosion resistance is also very good. Machining allowable cutting speed than ordinary stainless steel 2 to 3 times. Tests show that the processing of such steel than the production of ordinary stainless steel double the production efficiency.
