203 is stainless steel. Stainless Steel (Stainless Steel) is the abbreviation of stainless acid -resistant steel. Weak corrosive media such as air, steam, water or stainless steel is called stainless steel; Eclipse) Corrosive steel species are called acid -resistant steel. Due to the differences in chemical composition, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid -resistant steel is generally stainless. The term "stainless steel" is not just a kind of stainless steel, but it means more than 100 kinds of industrial stainless steel. Each stainless steel developed has good performance in its specific application field. It belongs to the chromium manganese -austenitic stainless steel. 203 stainless steel is not a food grade. 203 stainless steel is a 200 series stainless steel. It belongs to chromium and manganese -manga. The biggest advantage of the 200 series of stainless steel is that the thief is bright after polishing, and it is mostly used as decorative materials.
The austenitic stainless steel is divided into two series of chromium nickel (USA 300) Austenitic Stainless Steel and chromium manganese (200 Series) Austeen Stainless Steel.
Stainless steel is divided into five categories: Austeenia stainless steel, ferrite stainless steel, orchidine (double -phase) stainless steel, martensite stainless steel, and precipitated hardening stainless steel. A large number of circulation on the market is used to make building components, decoration parts, vehicle structures, guardrails, household appliances and shells, newsstances, telephone kiosks, catering utensils, medical appliances, etc. The austenitic stainless steel. Coupled with a large number of industrial use, the output (or consumption) of austenitic stainless steel accounts for about 75%to 80%of the total stainless steel output (or consumption).
Is 203 stainless steel a food grade? 203 stainless steel contains more carbon, so the material is harder, it is easy to crack at will. It is mostly used for decoration and other shallow stretch products. Require.
The biggest advantage of the 200 series of stainless steel is that the thief is bright after polishing, and it is mostly used for decorative materials. Dry -resistant ordinary natural environment corrosion.
The 200 series of stainless steel, due to the low requirements of use, there are not many qualified products produced in China according to standards. Many rusty stainless steels are this series of level products.
The difference between 203 stainless steel and 304 ingredients
The difference between the two is mainly the following:
1. The material composition is different.
203 stainless steel nickel content is about 4%, manganese content is about 8%, 304 stainless steel nickel content is about 8%, and it contains more than 18%chromium.
2. Different corrosion resistance. The chromium content of 304 stainless steel is greater than 203 stainless steel, and corrosion resistance is better than 203 stainless steel.
3. Different applications. 304 stainless steel is mainly used in food processing, storage and transportation, medical appliances, home supplies, car accessories, ripples, etc. 203 is used in building decoration, public facilities, municipal engineering, highway fences, shopping malls, glass armrests, etc. Due to the difference in nickel content, the cost of 203 stainless steel is less than 304 stainless steel. Therefore, 203 stainless steel is used to impersonate 304 stainless steel with 203 stainless steel. In the series, if you buy and use it wrongly, there will be great hidden dangers.
