Description of 201
201 stainless steel, with a certain acid and alkali resistance, high density and so on, is the production of various cases, strap back cover of high-quality materials. Mainly used for decorative pipe, industrial pipe, some shallow drawing products.
200 serial stainless steel sheets
China mainly has the following 200 kinds of steel grades: L1, LH, LA, L4, J1, J3, J4, 201, 202. Later on there appeared a lower nickel content control of 200 other grades of steel, as 201C, is the subsequent development of China's individual steel 201 varieties of steel, 201 national standard grades are: the old brand 1Cr17Mn6Ni5N, new grades: 12Cr17Mn6Ni5N 201C on the basis of 201 continue to reduce the nickel content, increase the manganese content.
201 and 304 stainless steel sheets
304 stainless steel and 201 stainless steel difference: the essence of the material listed on the difference, the chemical composition of the various elements of the content is different, so finished 304 performance corrosion resistance, stamping performance is far better than 201, 304 is generally used in complex environments, Where strong resistance to corrosion, 201 is used for environmental requirements is not very high, or less demanding on stainless steel, the price, 304 is much higher than the price of 201, according to the use of the environment, production The product quality requirements to choose the right material.
