Stainless steel plate has no magnetism or weak magnetism, and stainless steel 201 has magnetism. Ferritic stainless steel plate and austenitic stainless steel plate are called stainless steel 201. Generally speaking, stainless steel plate refers to martensitic stainless steel plate, so generally speaking, stainless steel 201 has less anti rust treatment capacity than stainless steel plate. Stainless steel 201 is magnesium and no nickel, aluminum iron core pulling rivet is also known as Cr stainless steel plate, it will have a certain corrosion resistance ability! Stainless steel 201 is not a common saying. It is popular to think that stainless steel plate with ferromagnetic material, while stainless steel plate contains both magnesium and nickel. Because nickel belongs to a more stable element, its corrosion resistance is certainly much better than that of stainless steel 201! Because the price of nickel is too high, the cost of stainless steel plate is higher than that of stainless steel 201. In addition, due to the difference in corrosion resistance, the price of stainless steel tube is higher than that of stainless steel 201. The electromagnetic coil of stainless steel plate is 30 yuan per kilogram, while that of stainless steel 201 electromagnetic coil is about 17 yuan. Therefore, the price of stainless steel rivets made of stainless steel plate is higher than that of stainless steel Steel 201 forged out of the stainless steel 201 bolts, external lock type wire drawing rivet characteristics are more excellent stainless steel rivets!
