在化工生产中经常碰到盐酸,硫酸等非氧化性介质,在这些介质中,通常使用的金属耐蚀材料,如镍—铬不锈钢,已不能满足耐蚀性能的要求。目前在这些部门主要采用非金属材料,设备跑冒滴漏现象严重,对生产影响很大,因此,研制新型耐蚀合金已成 In chemical production often encounter hydrochloric acid, sulfuric acid and other non-oxidizing media, in these media, commonly used metal corrosion-resistant materials, such as nickel-chromium stainless steel, can not meet the corrosion resistance requirements. At present, the non-metallic materials are mainly used in these departments, and the equipment runs a serious impact on production and dripping. Therefore, the development of a new type of corrosion-resistant alloy has become
