稳定化处理,是把含有稳定化元素(Ti、Nb、Ta)的18—8型钢加热到900℃左右,使碳化铬溶解,而溶解了的碳和钛(或Nb、Ta)化合成稳定的碳化物,不再有机会在晶间沉淀为碳化铬。从而改进耐蚀性的操作。稳定化处理在五十年代初国外已广泛使用。六十年代国内开始用于生产。但和可控气氛处理一样,机械行业走在了前面。冶金厂仅上钢三厂中板车间采用,该厂的1Cr18Ni9Ti中板全部以直接稳定化处理交货。在制定YB541—70和YB542—70两个标准的时候,有人提出将稳定化处理纳入标准,但未得到支持。
In the stabilization process, the 18-8 steel containing the stabilizing elements (Ti, Nb, Ta) is heated to about 900 ° C to dissolve the chromium carbide while the dissolved carbon and titanium (or Nb, Ta) are stably synthesized Carbides, no longer have the opportunity to precipitate in the intergranular chromium carbide. Thereby improving the corrosion resistance of the operation. Stabilization in the early 1950s has been widely used abroad. Sixties domestic began to be used for production. But like the controlled atmosphere, the machinery industry is ahead. Metallurgical plant only on the steel plant used in three workshops, the plant’s 1Cr18Ni9Ti plate in all direct stabilization of delivery. At the time of establishing the two standards YB541-70 and YB542-70, it was proposed that stabilization be included in the standard but not supported.
