什么是不锈钢，最为通俗的来说，就是要求含铬（Cr）量大于11%的铁基合金。不锈钢的抗生锈性源于合金中铬的存在，铬形成钝化膜，保护底层材料免受腐蚀。以常见的304材料为例，其对应的国标旧牌号为0Cr18Ni9，这里铬的含量就是18%。下面红线是大气中的腐蚀速率，大约在铬大于10%之后，腐蚀速率才是可以接受的。304不锈钢是一种很常见的不锈钢，业内也叫做18/8不锈钢。它的抗腐蚀性能要优于 430不锈铁，耐腐蚀耐高，加工性能好，因此广泛使用于工业和家具装饰行业和食品医疗行业，例如：一些高档的不锈钢餐具，浴室厨房用具。 What is stainless steel, the most popular speaking, is required to contain chromium (Cr) more than 11% of the iron-based alloy. The rust resistance of stainless steel stems from the presence of chromium in the alloy, and the chromium forms a passivation film to protect the underlying material from corrosion. Take the common 304 material as an example, the corresponding national standard old brand number is 0Cr18Ni9, where the content of chromium is 18%. The red line below is the rate of corrosion in the atmosphere, which is acceptable after chromium is greater than 10%.304 stainless steel is a very common stainless steel, also known as 18 / 8 stainless steel. Its corrosion resistance is better than 430 stainless iron, corrosion resistance is high, good processing performance, so it is widely used in industrial and furniture decoration industry and food and medical industry, such as: some high-grade stainless steel tableware, bathroom kitchen appliances.
