The difference between 201 steel Bai and 304 steel insulation Cup Du is that the two stainless steel materials are not the same.

The difference between 201 steel Bai and 304 steel insulation Cup Du is that the two stainless steel materials are not the same.

Specific Dao differences are as follows:

① The chemical formula of 201 is zhuanshu1cr17mn6ni5304 is 06cr19ni10; the main difference between them is Ni Cr element, 304 is 19 CR 10 Ni, and 201 is 17 CR 5 Ni.

② : 201 stainless steel contains manganese, but 304 does not; in terms of color, because the color of 201 stainless steel will be darker than 304, 304 will be white and bright, but this is not easy to distinguish with the naked eye.

③ Because of the different content of nickel, the corrosion resistance of 201 is far less than that of 304; the acid and alkali resistance of 201 is not as good as that of 304; because the carbon content of 201 is higher than 304, 201 is harder and brittle than 304, and 304 has better toughness. If you scratch the surface of 201 with a hard cutter, there will be obvious scratches, and the scratches on 304 will not be obvious.

④ : because 201 contains manganese, it will rust in humid and high salt air for a long time, while 304 will not rust.
