304/304L Stainless Steel Coil

Introduction:

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

 06Cr19Ni10 and SUS304 are commonly labeled in the market, among which 06Cr19Ni10 generally represents the national standard production, 304 generally represents the ASTM standard production, and SUS304 represents the daily standard production.

 304 is a universal stainless steel, which is widely used in making equipment and parts that require good comprehensive properties (corrosion resistance and formability). To maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and 8% nickel. 304 stainless steel is a brand of stainless steel produced in accordance with ASTM standards.

 Product standard:

 For 304 stainless steel, the Ni element in its composition is very important, directly determines the corrosion resistance of 304 stainless steel and its value.

 The most important elements in 304 are Ni and Cr, but they are not limited to these two elements. Specific requirements shall be specified by product standards. Industry common judgment that as long as the Ni content is greater than 8%, Cr content is greater than 18%, can be considered 304 stainless steel. This is why the industry will call this type of stainless steel 18/8 stainless steel. In fact, the relevant product standards for 304 has very clear provisions, and these product standards for different shapes of stainless steel and some differences. Here are some common product standards and tests.

 Application:

 System description: 304 stainless steel is one of the most widely used cr-ni stainless steel [1]. As a kind of steel with a wide range of USES, it has good corrosion resistance, heat resistance, low temperature strength and mechanical characteristics. Stamping, bending and other thermal processing, no heat treatment hardening phenomenon (use temperature -196℃ ~ 800℃). Corrosion resistance in the atmosphere, if it is industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. Good machining performance and weldability. Plate heat exchanger, bellows, household products (1, 2 tableware, cabinet, indoor pipeline, water heater, boiler, bathtub), auto parts (windshield wipers, muffler, mold products), medical appliances, building materials, chemistry, food industry, agriculture, ship parts, etc. 304 stainless steel is food grade stainless steel.
