补充资料：预应力锚夹具用钢
制作预应力构件用锚夹具的钢材。每一种锚具或夹具都是由几个零件所组成。各零件由于功能要求、冷热加工方法和生产工艺不同，因而所用钢材也各不相同。目前，消耗量最大、用途最广的是中碳钢和中碳低合金钢,其中以优质碳素钢45为主。工作应力较低的零件,是以热轧圆钢直接制成；工作应力较高的零件，则常在冷加工后进行调质处理。夹持式的锚具和夹具中，与预应力筋接触的带齿零件，需要具有更高的表面硬度来提高锚、夹具的锚固性能。所以采用优质碳素钢45和弹簧钢(如65锰等)时，要求用盐液淬火后经低温回火处理；采用低碳或低碳低合金钢(如优质碳素钢15、20或20铬等)、低碳易切削钢（如易20等）时，要求表面渗碳或碳氮共渗。预应力筋强度不高、锚具效率要求不高时，也曾大量使用过铸钢（相当于中国的ZG45）。
