贝氏体球铁具有强度高、韧性好、加工性能优良、成本低等优点。因而可生产较轻的零件,应用于运输传动设备上。如美国 Cummins 公司的 B 系列柴油机定时齿轮,用贝氏体球铁取代锻钢和渗碳钢后,成本节约了30%。福特公司的涡轮增压式发动机曲轴,为提高疲劳强度和降低成本,计划在1987年,用贝氏体球铁取代传统球铁。德国 GGG100卡车弹簧支架,用贝氏体球铁取代铸钢。瑞典有一种轨车轴箱弹簧联接器,用贝氏体球铁取代传统球铁后,重量
Bainite ductile iron with high strength, good toughness, excellent processing performance, low cost and so on. It can produce lighter parts, used in transportation transmission equipment. Such as the United States Cummins’s B series of diesel timing gears, with bainitic ductile iron instead of forged and hardened steel, the cost savings of 30%. Ford’s turbocharged engine crankshaft, in order to improve fatigue strength and reduce costs, is planned in 1987, with bainitic ductile iron to replace the traditional ductile iron. Germany GGG100 truck spring bracket, with bainitic cast iron instead of cast steel. Sweden has a rail axle box spring coupling, with bainite ductile iron to replace the traditional, the weight
