1. The commonly used stainless steel plates are divided into 201 and 304 steel grades. The actual composition is different. The quality of 304 is better, but the price is expensive, and 201 is worse.
2. The composition of 201 stainless steel strip is 17Cr-4.5Ni-6Mn-N, which is a Ni steel grade and an alternative to 301 steel. It is magnetic after cold working and is used in railway vehicles.
3. The composition of 304 stainless steel strip is 18Cr-9Ni, which is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc.
4. The 201 stainless steel belt is high in manganese, the surface is very bright with dark light, and the high manganese content is easy to rust. The 304 stainless steel belt contains more chromium, and the surface is matte and does not rust. The two are compared together.
304 stainless steel strip is the most widely used kind of chromium-nickel stainless steel. As the most widely used steel, it has good heat resistance, corrosion resistance, low temperature strength and mechanical properties. Stamping, bending and other hot workability is good, no heat treatment phenomenon (use temperature -196 ℃ ~ 800 ℃). It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion.
304 stainless steel belt is suitable for food processing, storage and transportation. Has good workability and weldability. Plate heat exchangers, bellows, household goods, auto parts (windshield wipers, mufflers, moldings), medical appliances, building materials, chemicals, food industry, agriculture, ship parts, etc.
