Method of fabrication of distortion-resistant material

摘要

Method of fabrication of material suited for use in a thermal reactor according to which austenitic stainless steel is dipped in a bath of molten aluminium in addition of silicon and then receives heat treatment in specific temperature ranges, whereby preferential diffusion of silicon in the steel material is effected. The diffused silicon prevents diffusion of aluminium and ensures that thickness of plating layers remains at a value such that distortion of a plated element does not occur even after prolonged service.
