什么是不銹鋼,最為通俗的來說,就是要求含鉻(Cr)量大于11%的鐵基合金。不銹鋼的抗生銹性源于合金中鉻的存在,鉻形成鈍化膜,保護底層材料免受腐蝕。以常見的304材料為例,其對應的國標舊牌號為0Cr18Ni9,這里鉻的含量就是18%。下面紅線是大氣中的腐蝕速率,大約在鉻大于10%之后,腐蝕速率才是可以接受的。304不銹鋼是一種很常見的不銹鋼,業(yè)內(nèi)也叫做18/8不銹鋼。它的抗腐蝕性能要優(yōu)于 430不銹鐵,耐腐蝕耐高,加工性能好,因此廣泛使用于工業(yè)和家具裝飾行業(yè)和食品醫(yī)療行業(yè),例如:一些高檔的不銹鋼餐具,浴室廚房用具。 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.
