Product Details

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

06cr19ni10 and SUS304 are the common marking methods on the market, of which 06cr19ni10 is generally produced according to the national standard, 304 is generally produced according to the ASTM standard, and SUS 304 is produced according to the Japanese standard.

304 is a kind of universal stainless steel, which is widely used to make equipment and parts requiring good comprehensive performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a brand of stainless steel produced according to American ASTM standard.

Application Scope

System Description: 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 working properties such as stamping and bending, and no 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. Suitable for food processing, storage and transportation It has good machinability and weldability Plate heat exchanger, corrugated pipe, household products (Class 1 and 2 tableware, cabinet, indoor pipeline, water heater, boiler, bathtub), auto parts (windshield wiper, muffler, mold products), medical appliances, building materials, chemistry, food industry, agriculture, ship parts, etc. 304 stainless steel is a national recognized food grade stainless steel.

Most of the use requirements are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere and the cleaning system to be adopted However, more and more other applications are only looking for structural integrity or impermeability. For example, roofs and side walls of industrial buildings. In these applications, the owner's construction cost may be more important than aesthetic, and the surface may not be very clean 304 stainless steel is very effective in dry indoor environment. However, in rural and urban areas, if you want to maintain its appearance outdoors, you need to wash it frequently. In the polluted industrial areas and coastal areas, the surface will be very dirty, even produce rust.

However, in order to obtain the aesthetic effect in outdoor environment, it is necessary to use stainless steel containing nickel. Therefore, 304 stainless steel is widely used for curtain wall, side wall, roof and other building purposes, but in the corrosive industrial or marine atmosphere, 316 stainless steel is the best choice Stainless steel sliding doors, people have fully realized the advantages of using stainless steel in structural applications. Several design criteria include 304 and 316 stainless steel. Because "duplex" stainless steel 2205 has integrated good atmospheric corrosion resistance with high tensile strength and elastic limit strength, it is also included in the European code In fact, stainless steel is made of full standard metal shapes and sizes, and there are many special shapes. The most commonly used products are made of sheet and strip steel, as well as special products made of medium and thick plates, such as hot-rolled structural steel and extruded structural steel. In addition, there are round, elliptical, square, rectangular and hexagonal welded or seamless steel pipes and other products, including profiles, bars, wires and castings.
