产品详情

超级奥氏体不锈钢

当铬镍奥氏体不锈钢的耐点蚀当量值(PREN=[Cr]+3.3[Mo]+16[N])≥40%,便可称为超级奥氏体不锈钢。超级奥氏体不锈钢主要是为解决在含Cl-的苛刻腐蚀条件下原有的高钼(>4%)铬镍奥氏体不锈钢耐点蚀、耐缝隙腐蚀等性能的不足和组织热稳定性差而发展起来的。

主要牌号:N08904(904L), N08367(6Mo), S31254(6Mo), S30432, S31042

主要标准(部分):

ASTM A312 无缝和焊接奥氏体不锈钢管

ASTM A269 一般设备用无缝和焊接奥氏体不锈钢管

ASTM B673,ASTM B674,ASTM B677,ASTM B675,ASTM B676, ASTM B690

性能特点:

1.在苛刻的腐蚀环境中,耐点蚀、耐缝隙腐蚀性优异

2.力学性能优良,屈服强度高

3.良好的可加工性
