不锈钢为什么也生锈?当不锈钢表面出现褐色锈斑点的时候,人们大感惊奇:认为“不锈钢是不生锈的,生锈就不是不锈钢了。可能是钢质出现了问题”。其实,这是对不锈钢缺乏了解的片面看法。不锈钢在一定条件下也会生锈,在含酸、碱、盐的介质中也会被腐蚀,其抗腐蚀能力的大小是随其钢质本身化学组成、加互状态,使用条件及环境介质类型而改变的。如 Why stainless rust? When the stainless steel surface brown rust spots, people were surprised: “stainless steel is not rusty, rust is not stainless steel may be a steel problem”. In fact, this is a one-sided view of the lack of understanding of stainless steel. Stainless steel will rust under certain conditions and will also be corroded in the medium containing acid, alkali and salt. The corrosion resistance of stainless steel will vary with the chemical composition of its own steel, plus the mutual state, the conditions of use and the type of environmental medium And change.
