近日,我司完成一批换热器用俄标08Cr21Ni6Mo2Ti材质双相不锈钢无缝管的生产。尺寸为25*2.5*14010mm。此材质近似于美标S32205, 欧标1.4462或国标S22053。
铁素体奥氏体双相不锈钢因为其较高的铬钼含量以及其铁素体奥氏体双相组织,具有比奥氏体不锈钢更好的耐氯离子点腐蚀和应力腐蚀性能以及高强度。但双相不锈钢一般用在中性氯化物环境,在含有硫酸盐酸等酸性氯化物环境会产生两相的选择性加速腐蚀。 同时双相不锈钢的有害相析出非常敏感,如果无缝管制造工艺不完全正确,导致有害相的析出,将严重影响管子的机械性能,冲击性能,使管子变脆,降低管子的耐腐蚀性能。因此,检测双相不锈钢无缝管的重点应该放在机械性能,扩口,压扁,冲击,两相比例及耐点腐蚀性能方面,而不是化学成分。
在把握材料性能,制订正确工艺的前提下,我司生产出了多批次各方面性能优异的低铬钼,中铬钼,高铬钼的全系列双相不锈钢无缝管。包括国标,美标,欧标,日标,俄标等标准上的各种材质,代表性美标钢种包括S31500, S32101, S32304(低铬钼), S31803, S32205(中铬钼), S31260, S32550, S32750, S32760(高铬钼), S32707(特超级双相钢)。
