通过高温拉伸试验、冲击试验以及抛光试验研究了铜和硫对4Cr13钢加工性能的影响。研究表明，铜、硫的加入未引起4Cr13钢变形抗力的改变。4Cr13Cu钢的热塑性低于4Cr13钢，但高于4Cr13S钢。硫明显降低了4Cr13钢的冲击韧性，尤其是横向冲击韧性。相反，铜则显著提高了4Cr13钢的冲击韧性。铜、硫均降低了4Cr13钢的抛光性能。
The effect of copper and sulphur on mechanical properties of stainless steel 4Cr13 were studied by high temperature tensile test, impact test and polish test. Results showed that high temperature resistance of deformation of 4Cr13 is not changed by adding copper and sulphur. The percentage reduction in area of 4Cr13 is decreased by adding copper and sulphur. The impact toughness of 4Cr13 is decreased by adding sulphur, while increased by adding copper. The roughness of polished surface of 4Cr13 is increased by adding copper and sulphur.
