What's the difference between stainless steel 20 1 and 4 10?

1, each with its own characteristics. ? 4 10 is a kind of stainless steel with good corrosion resistance and machinability. 20 1 stainless steel has certain acid and alkali resistance, high density and no bubbles and pinholes in polishing.

2. Different uses. 4 10 steel is generally used for blades, mechanical parts and 1 tableware (spoons, forks, knives, etc. ); 20 1 steel is a high-quality material for producing all kinds of watchcases and watchbands, which is mainly used for decorative tubes, industrial tubes and some lightly stretched products.

3, 4 10 magnetic 20 1 nonmagnetic.

4. The chemical composition is different.

Chemical composition of 4 10 stainless steel: C≤0. 15, Si≤ 1.00, Mn≤ 1.00, P≤0.035, S≤0.030, Cr =1.

Chemical compoSition of 20 1 stainless steel: (c) carbon ≤0. 15, (si) silicon ≤ 1.00, (Mn) manganese ≤ 5.5 ~ 7.50, and (Cr) chromium ≤16.0.
