不锈钢制品的大量使用是厨房里的一道美丽的风景线，它们漂亮，耐用，易清洁，直接改变了厨房的色彩和触感。厨房视觉环境因此获得了很大的提升。

The extensive use of stainless steel products is a beautiful scenery line in the kitchen, they are beautiful, durable, easy to clean, and directly change the color and touch of the kitchen.The kitchen visual environment has therefore been greatly improved.

但是，不锈钢有很多种，中间的差别不小，偶尔还会听到安全性疑问，挑选起来是个问题。

尤其是到了锅，餐具等直接承载食物的器具，材料就显得更加敏感。怎样去分辨它们？佛山市万庆物资认为，厨房里的一切，大家都应该用得明明白白。

However, there are many kinds of stainless steel, the difference between the middle is not small, occasionally will hear safety questions, pick up is a problem. Especially to the pot, tableware and other utensils directly carrying food equipment, the material is more sensitive.How do you tell them apart?Foshan City Wanqing material believes that everything in the kitchen, everyone should use clearly.

不锈钢是什么东西？

What is stainless steel?

不锈钢的特别之处，是两种元素决定的，这便是铬和镍。没有铬就不是不锈钢，而镍的多少，决定了不锈钢的身价。

What stainless steel is special is determined by two elements, which are chromium and nickel.No chromium is not stainless steel, and the number of nickel, determines the value of stainless steel.

不锈钢能在空气中保持光泽，不生锈，是因为含有一定量的铬合金元素（不低于10.5%），它能使钢材表面形成一层不溶解于某些介质的坚固的氧化薄膜。

Stainless steel can maintain luster in the air without rust, because it contains a certain amount of chromium alloy elements (not less than 10.5%), which enables the surface of the steel to form a solid oxide film that does not dissolve in certain media.

加入镍元素后，不锈钢性能进一步提高，在空气中、水中、蒸汽中、都具有很好的化学稳定性，而且在许多种酸、碱、盐的水溶液中也有足够的稳定性，甚至在高温或低温环境中，仍能保持其耐腐蚀的优点。

After adding nickel element, stainless steel performance is further improved, in the air, water, steam, have a very good chemical stability, and in many kinds of acid, alkali, salt aqueous solution also has enough stability, even in high temperature or low temperature environment, still can maintain its corrosion resistance advantages.

按照微观组织结构，不锈钢有马氏体型、奥氏体型、铁素体和双相不锈钢之分。奥氏体塑性好，强度较低，具有一定韧性，易于加工成型，不具有铁磁性。

According to the microstructure, stainless steel has martenitic, austenite, ferrite and duplex stainless steel.Austenite has good plasticity, low strength, has a certain toughness, is easy to process and shape, and is not ferromagnetic.

奥氏体不锈钢在不锈钢中一直扮演着最重要的角色，其生产量和使用量约占不锈钢总产量及用量的70%。钢号也最多，所以，你日常见到的绝大多数不锈钢都是奥氏体不锈钢。

Austenitic stainless steel has always played the most important role in stainless steel, and its production and use account for about 70% of the total production and consumption of stainless steel.Steel is also the most, so most of the stainless steel you see everyday is austenitic stainless steel.

人们所熟知的304钢就是奥氏体不锈钢，之前的中国国标为0Cr19Ni9(0Cr18Ni9)，意思是含Cr(铬)19%，含Ni(镍）9%。0指含碳量<=0.07%。

The 304 steel is well known as austenitic stainless steel, with the previous Chinese national standard of 0Cr19Ni9 (0Cr18Ni9), which means containing Cr (chromium) 19% and Ni (nickel) 9%.0 refers to carbon content
