What is the difference between 304 and 316 stainless steel pipes (the difference and application field of 304 and 316 stainless steel pipes)
Chemical composition, properties and uses of 303 and 316 stainless steel pipes
1, the general composition of stainless steel
304 stainless steel pipe is one of the most commonly used stainless steel pipe. Stainless steel is a high-alloy steel, and because of its excellent corrosion resistance, stainless steel pipes are increasingly used in acid-base environments and cleaning industries. Since it is steel, of course, it must contain carbon, chromium and other carbides and metal elements.
2. Different chemical composition
Type 304 chemical composition is: C≤0.08, Si≤1.00, Mn≤2.00, P≤0.035, S≤0.03, Ni: 8.0-10.5, Cr: 18.0-20.0.
Type 316 chemical composition is: C≤0.08, Si≤1.00, Mn≤2.00, P≤0.035, S≤0.03, Ni: 10.0-14.0, Cr: 16.0-18.0, Mo: 2.0-3.0.
3. There are differences in nature
In daily life, we can see many kinds of stainless steel products, including stainless steel sinks, stainless steel toolboxes, stainless steel POTS and stainless steel pipes. Generally speaking, 304 stainless steel pipe corrosion resistance is strong, suitable for general environment; 316 stainless steel pipe corrosion resistance is significantly better, suitable for more harsh environments, especially in the case of high chlorine content.
4, application field differentiation
The application range of 304 stainless steel pipe is mainly concentrated in the food, chemical and beauty industries, such as food equipment, surface treatment equipment, pharmaceutical equipment, electronic equipment and various shrouds, Windows, tracks, corridors and so on.
316 stainless steel pipe application range is relatively complicated and extensive, including pharmaceutical, food, pulp and paper, Marine engineering, shipbuilding, chemical and seawater desalination industries, is the best corrosion resistance of stainless steel, can withstand high concentrations of chloride ions strong corrosion, therefore, especially suitable for chloride environment.
