A abrasion resistant steel has been developed for hydraulic turbine components. The tensile strength of 550MPa and hardness HRC60~62 can be obtained. The mass loss rate of the steel can be decreased to one~thircd as compared with oCr13Ni4Mo steel. 发展了一种抗磨蚀多元系莱氏体铸钢ZG93L，经淬火、回火后，抗拉强度近550MPa，硬度为60HRC以上，其抗磨蚀性比0Cr13Ni4Mo钢高1.
The high hardness and toughness in the abrasion resisting steel after quenching and tempering two times is due to bainite formation in the l... 在二次加热淬火回火中出现高硬度、高韧性值,是因为衬板淬火过程中在具备贝氏体生成的冷却速度下生成了贝氏体组织。
They put forward the optimum tempering process for non-cabide bainite abrasion resisting steel, in addition,introduced the applied effect of ... 提出了适合无碳化物贝氏体耐磨钢的最佳回火工艺,并介绍了无碳化物贝氏体钢的工况及应用结果。
