SA662GrC美标合金容器板屈服抗拉性能和成分说明

1、是河钢舞钢生产的，中低温压力容器用碳锰硅钢板，主要用于制造低温焊接压力容器，对低温缺口韧性有较高要求的焊接压力容器用碳-锰-硅钢板。用于制造—40℃状态下使用的低温焊接压力容器。例如：制作反应器、换热器、分离器、球罐、油气罐、液化汽罐、核能反应堆压力壳、锅炉汽包、液化石油汽瓶、水电站高压水管、水轮涡壳等设备及构件。 2、的执行标准是：美国材料与实验协会标准ASTM（ASME）ASME A662/、交货状态：正火4、化学元素：5、力学性能：6、热处理：所有A级钢板和厚度大于40mm的B级和c级钢板都应该正火。厚度小于等于40mm的B级和C级钢板通常以轧制状态供应。也可以正火消除应力处理或正火加消除应力处理供应。7、生产工艺流程：电炉冶炼→LF/VD炉精炼→铸锭→钢锭清理→钢锭加热→轧板→超声波探伤→正火→精整→检验→入库8、制造：炼钢工艺-钢应为镇静钢,应符合A20/A20M标准细奥氏体晶粒度的要求。9、应用范围：应用于石油、化工、电站、锅炉等行业，用于制作反应器、换热器、分离器、球罐、油气罐、液化汽罐、核能反应堆压力壳、锅炉汽包、液化石油汽瓶、水电站高压水管、水轮涡壳等设备及构件。
