Study on Low Spheroidizing Annealing of SWRCH10A Cold Heading Steel Coil Rod
Pages: 62-65

Keyword:  WARCH10A盘条低温球化退火球化工艺;
Abstract: 根据市场需求,对使用低碳冷镦钢SWRCH10A生产紧固件及非标零件的球化工艺进行了研究.SWRCH10A为日本钢号,常在低于Ac1温度以下进行低温球化处理后使用.对影响产品球化效果的工艺路线,球化温度以及形变量三方面因素进行了实验分析.结果表明:1)先形变处理后球化工艺较之先球化后形变处理以及不进行球化直接进行形变的工艺球化效果好;2)球化温度680℃时硬度满足客户要求,且提高了材料的塑性,降低了材料的开裂倾向.
