Description

Material: 304/316/201 stainless steel
201, 304 and 316 are three common stainless steel grades, each with different advantages and properties.
201 stainless steel: 201 stainless steel has a certain degree of acid and alkali resistance, high density, bubble-free polishing, no pinholes and other characteristics. It is mainly used for the production of decorative pipes, industrial pipes and some flat stretched products. However, the corrosion resistance of 201 stainless steel is worse than that of 304 and 316 stainless steel due to the lower nickel content.
304 stainless steel: 304 stainless steel is the most widely used type of chromium-nickel stainless steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It is resistant to corrosion in the atmosphere. In industrial atmosphere or heavily polluted areas, it must be cleaned in time to prevent corrosion. The sheet is suitable for food processing, storage and transport and is easy to bend and weld.
316 stainless steel: 316 stainless steel is a kind of 304 after the second to become the most widely used steel, the main characteristics of strong acid resistance (especially nitric acid), add molybdenum elements to make it get a special structure of corrosion resistance. Due to its better resistance to chloride corrosion than 304, it is also used as "marine steel".
