超级马氏体不锈钢

显组织

超级马氏体不锈钢典型的基体金属显组织为回火马氏体。这种低碳回火马氏体组织具有很高的强度和韧性。根据含镍量的不同、热处理条件的差异，一些牌号的超级马氏体不锈钢基体显组织中可能会出现10％～40％的细小弥散状残留奥氏体。对于含铬16％等级的超级马氏体不锈钢，显组织中可能出现少量的δ铁素体。为了获得理想的细晶粒回火马氏体，在钢板交货之前一般都经过淬火加回火处理。

机械性能

超级马氏体不锈钢不仅具有较好的耐腐蚀性、可焊接性，而且具有强度高和低温韧性好的特点。典型的机械性如下：

延伸率大于12％

焊接性能

马氏体不锈钢含铬13％，由于铁素体晶粒在焊接过程中粗化和硬化，而使其可焊性很差。以往，这类不锈钢的用途严格限制于非焊接零件的安装。经过冶炼工艺的不断改进，降低了马氏体不锈钢中的碳、氮、硫含量，又增加了一定量的镍（ 含量达6.5％）和钼（ 含量2.5％），从而开发出了超级马氏体不锈钢。这种材料在加工制造过程中又采取了特殊的工艺措施，使得新的超级马氏体不锈钢的焊接性能大大超过了传统的马氏体不锈钢。

超级马氏体不锈钢的焊接可以采用人们熟悉的焊接工艺，诸如气体保护金属极电弧焊（GMAW或SMAW），气体保护钨电弧焊（GTAW）。埋弧焊（SAW）和励磁线圈电弧焊（FAW）。对于环缝焊接可以使用GTSW、GMAW和SAW，直缝焊大多数使用SAW。但是，激光焊和电子束焊也非常有吸引力。激光焊对生产直缝焊管是一种经济的焊接方法。由于冷却速度快，在焊缝中可以获得全马氏体显组织，从而得到很好的韧性和满意的耐蚀性。

耐蚀性能

超级马氏体不锈钢由于含碳量低，相当于提高了基体金属中含铬量的比例，所以耐腐蚀性好。

对于弱酸性腐蚀环境，超马氏体不锈钢有取代其它耐蚀合金的趋势。但是，在高温和有二氧化碳存在的腐蚀条件下，会产生一般腐蚀和局部腐蚀，在二氧化碳和硫化氢同时存在的腐蚀条件下，必须考虑在室温下产生的应力腐蚀裂纹和在高温下产生的局部腐蚀和一般腐蚀。根据腐蚀条件的不同（如CO2或CO2＋H2S），开发了不同牌号的超马氏体不锈钢（含钼或不含钼）。这种超13Cr不锈钢已成功地应用于北海地区的Gullfaks油田和Asgard油田。
