高强不锈钢的应用,其中包括在不同气候条件下工作的焊接结构上的应用,要求找出用复层来防止可能的腐蚀开裂的保护方法。当不能用更可靠的其它使用性能相等的材料来代替,不容许采用包括消除或大大降低残余拉应力在内的其它热处珲工艺;不允许能形成压应力的表面处理方法,不能进行旨在消除残余应力的零件热处理,并且又不可能改变腐蚀介质,包括添加抑制剂时,采用这种保护是必不可少的。
The use of high-strength stainless steels, including welded structures that operate under different climatic conditions, requires the identification of protection methods that prevent possible corrosion cracking with multiple layers. When not more reliable use of other materials with the same performance, does not allow including the use of eliminate or greatly reduce the residual tensile stress, including other heat treatment process; does not allow the formation of compressive stress surface treatment methods, can not be carried out Elimination of residual stress parts heat treatment, and impossible to change the corrosive medium, including the addition of inhibitors, the use of such protection is essential.
