1.前言论及化工设备所使用的材料,很自然地就会想到不锈钢。它同铬钼钢一样是典型的化工设备用材料。但具有优良的抗连续腐蚀性能的不锈钢,一旦环境条件改变,也很容易发生孔蚀、应力腐蚀破裂等局部腐蚀。使用经验多了,资料数据随之增多,不过困难也多了。近年来已研制出多种耐孔蚀、耐应
1. Introduction Speaking of materials used in chemical equipment, it is natural to think of stainless steel. Like chromium molybdenum steel it is a typical chemical equipment materials. But with excellent continuous corrosion resistance of stainless steel, once the environmental conditions change, but also prone to pitting, stress corrosion cracking and other local corrosion. More experience, data data will increase, but more difficult. In recent years has developed a variety of pitting resistance, resistance should
