试验表明：经过表面淬火的铸钢和经过贝氏体淬火的球墨铸铁，其接触疲劳寿命和耐磨性大幅度提高。
The test indicates that contact fatigue life and wear resistance of surface quenched casting steels and Bainite quenched spherical cast iron are increased largely.
拥有有大型落地磨床、大型立式车床、数控车床、贝氏体等温淬火热处理生产线等先进生产设备。
There is a large landing has a grinder, a large vertical lathe, CNC lathe, bainite isothermal quenching heat treatment production line and other advanced production equipment.
采用阶段等温淬火可得粒状贝氏体球铁，这种球铁具有优良的综合机械性能。
The granuler bainite ductile iron can be obtained with the help of step austempering. This kind of ductile iron presents the excellent combination of mechanical properties.
