通过对非调质 12Mn2VBS钢的抗拉强度、屈服强度、延伸率、断面收缩率、硬度、冲击韧性等性能指标的测定 ,研究了非调质 12Mn2VBS钢中硫含量对组织性能及应用的影响。通过对硫含量的调整 ,可知非调质 12Mn2VBS钢的基本性能指标能够达到甚至超过 40Cr等调质钢的基本性能
The influence of sulfur content in non-quenched and tempered 12Mn2VBS steel on the microstructure and properties was studied by measuring the properties of non-tempered 12Mn2VBS steel such as tensile strength, yield strength, elongation, reduction of area, hardness and impact toughness. Through the adjustment of sulfur content, it can be seen that the basic performance index of non-quenched and tempered 12Mn2VBS steel can reach or exceed the basic performance of quenched and tempered steel such as 40Cr
