304 (UNS S30400, 1.4301) stainless steel is a universal stainless steel, it is widely used to make equipment and machine parts that require good comprehensive performance. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard.

The most important elements in 304 stainless steel are Ni and Cr, but they are not limited to these two elements. The specific requirements are stipulated by the product standards. The common judgment in the industry is that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel.

Overview of ASTM A240 304 Stainless Steel Strips:


304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm3, which is also called 18/8 stainless steel in the industry. High temperature resistance of 800 degrees, with good processing performance and high toughness, it is widely used in industry and furniture decoration industry and food and medical industry.


304 is a versatile stainless steel, which is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard.


Common labeling methods on the market include 06Cr19Ni10 and SUS304, among which 06Cr19Ni10 generally means national standard production, 304 generally means ASTM standard production, and SUS 304 means Japanese standard production.

Application of Stainless Steel 304 Strip and Coils:


304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending without heat treatment. Hardening 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. It is suitable for food processing, storage and transportation.


304 stainless steel has good processing properties and weldability. Plate heat exchangers, bellows, household products (category 1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry , Agriculture, ship parts, etc.
