Type

China mainly has the following 200 series steel types: J1, J3, J4, 201, 202. Later, there were 200 steel grades with lower nickel content control. As for 201C, which was an extension of 201 steel developed by some steel mills in China in this later period, the national standard grades for 201 were: the old grade 1Cr17Mn6Ni5N and the new grade: 12Cr17Mn6Ni5N 201C continues to reduce the nickel content and increase the manganese content on the basis of 201.

They different between 201 and 304

1, the use of 304 stainless steel: suitable for food processing, storage and transportation. Has good processability and solderability. Plate heat exchangers, bellows, household products (type 1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs);

Auto parts (windshield wiper, muffler, molded products), medical appliances, building materials, chemicals, food industry, agriculture, marine parts, etc. 304 stainless steel is a nationally recognized food-grade stainless steel.

2, 201 stainless steel uses: This product belongs to high manganese low nickel stainless steel, low nickel content, poor corrosion resistance, in various desktops, countertops, kitchenware, outdoor decoration engineering and urban decoration industry and high-end household products.
