如何選擇耐晶間腐蝕不銹鋼材料牌號
不(bu)銹鋼(gang)的(de)晶(jing)間腐(fu)(fu)蝕(shi)(shi)(shi)(shi)、點(dian)蝕(shi)(shi)(shi)(shi)、應力腐(fu)(fu)蝕(shi)(shi)(shi)(shi)和(he)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)疲勞等腐(fu)(fu)蝕(shi)(shi)(shi)(shi)類(lei)型均(jun)屬局部腐(fu)(fu)蝕(shi)(shi)(shi)(shi)。由于引起這類(lei)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)的(de)機(ji)理不(bu)同(tong)，其(qi)解(jie)決途徑也(ye)各不(bu)相(xiang)同(tong)。在這些局部腐(fu)(fu)蝕(shi)(shi)(shi)(shi)中以應力腐(fu)(fu)蝕(shi)(shi)(shi)(shi)破壞事故(gu)最(zui)多(duo)，約占(zhan)總腐(fu)(fu)蝕(shi)(shi)(shi)(shi)事故(gu)的(de)40%~60%,點(dian)蝕(shi)(shi)(shi)(shi)和(he)縫隙腐(fu)(fu)蝕(shi)(shi)(shi)(shi)事故(gu)約占(zhan)20%,晶(jing)間腐(fu)(fu)蝕(shi)(shi)(shi)(shi)和(he)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)疲勞各占(zhan)10%,均(jun)勻腐(fu)(fu)蝕(shi)(shi)(shi)(shi)占(zhan)10%....
