【摘要】 高铬钼抗磨合金本质为亚共晶型高合金白口铸铁。成分中cr/c=5～7;铸态硬度达HRc47～56;淬火后硬度HRc58～64;其金相组织为马氏体基本上（含有残留奥氏体）分布可观数量共晶型和二次合金碳化物,主要为（Fe,Cr）₇C3型具有较高的磨损抗力。适于电厂、建材、冶金、矿山等部门抗磨粒磨损零部件的制造,特别适用承受冲刷磨粒磨损零部件的制造。具有显著经济效益。更多还原

【Abstract】 High chromium-Molybdonum wear-resistant alloys are hypoeutectic white cast iron. Composition of alloys Cr/C =5～7; cast hardness is HRC-47～56; air guenched hardness is HRC58～64. The microstructure is martensitic matrix to distribnte considerably eutectic and secondary carbide (Fe,Cr)7C3. It has exce 11ent wear resistant ability, suitable for power plant, constract and material metallurgy and mining abrasive wear — resistant parts; specially esuitable for service on abrasive resisting parts. It has remarkable economic benefit.更多还原
