Will 304 stainless steel and 301 stainless steel What is the difference?
1, specifications: commonly used stainless steel sheet is divided into 201 and 304 two models, the actual composition is different, 304 quality better, but the price is expensive, 201 worse. 304 for the import of stainless steel, 201 for the domestic stainless steel plate.
2, 201 composition of 17Cr-4.5Ni-6Mn-N, is the section of Ni steel, 301 steel alternative steel. After cold processing with magnetic, for railway vehicles.
3, 304 composition of 18Cr-9Ni, is the most widely used stainless steel, heat-resistant steel. For food production equipment, the former chemical equipment, nuclear energy and so on.
4, 201 is a high manganese content, the surface is very bright with dark black, high manganese content is easy to rust. 304 chrome more, the surface showing matte, no rust. Two put together there is a comparison. The most important thing is the corrosion resistance of different, 201 corrosion resistance is poor, so the price will be much cheaper. And because 201 nickel low, so the price is lower than 304, so corrosion resistance is not as good as 304.
5, 201 and 304 is the difference between the nickel-containing problem. And the price of 304 are now more expensive, generally close to 50000 a ton, but at least 304 can guarantee that the use of the process will not rust. (Can be used to do the experiment)
6, stainless steel is not easy to rust because the surface of the steel body to form chromium-rich oxide can protect the body, 201 material is high manganese stainless steel 304 hardness higher carbon low nickel.
7, the composition of different (mainly from carbon, manganese, nickel, chromium and other aspects to distinguish between 201 and 304 stainless steel)
Steel (C) silicon (Si) manganese (Mn) phosphorus (P) sulfur (S) chromium (Cr) nickel (Ni) molybdenum (Mo) copper (Cu)
AISI (304) ≤0.08 ≤1.00 ≤2.00 ≤0.045 ≤0.03 18-20 8-10
AISI (201) ≤0.15 ≤1.00 5.5-7.5 ≤0.05 ≤0.03 16-18 3.5-5.5
The difference between stainless steel 301 and 304:
1,301 GB label 1Cr17Ni7; 304 GB label 0Cr18Ni9
2,304 is a versatile stainless steel that is widely used in the manufacture of equipment and components that require good overall performance (corrosion resistance and formability). 301 Stainless steel exhibits a significant work hardening during deformation, Requires higher strength for various occasions.
3,301 material compared with 304 steel, C content, Cr, Ni content is small, cold work, tensile strength and hardness increased, non-magnetic, but after cold magnetic.
