steel and temper

The effects of quenching temperature, cooling pattern, temper temperature and temper times on the structure and properties of high carbon and vanadium high speed steel ( HSS) roll were researched and the optimal heat treatment technical parameters were determined.

研究了淬火温度、冷却方式、回火温度和回火次数对高碳高钒高速钢轧辊组织和性能的影响，确定了最佳热处理工艺参数。

The residual deleterious elements in steel lead to products occurring red brittleness surface crack and temper brittleness, and lead to hot strength of heat resistant steel decreasing.

钢中的残余有害元素致使钢材产生红脆性表面裂纹和具有回火脆性倾向，并使耐热钢的热强性降低。

In 58 the soil blast furnace temper and steel with fire everywhere greatly!

58年遍地土高炉大炼钢铁!

A series of experimental Si-Mn series spring steel which has different vanadium content was smelt in laboratory by Fe-V or VN alloying. The penetration hardenability, temper resistance, surface decarbonization and mechanical properties of the test steel were studied.

分别采用VN、Fe-V合金在实验室冶炼了不同钒含量的Si-Mn系弹簧钢，并系统研究了其淬透性、抗回火稳定性、表面脱碳敏感性和力学性能的变化情况。
