What types of stainless steel
(1) Stainless steel strip
Strip material: 2B glossy surface, NO.1 industrial surface, BA (6K) mirror surface, 8K mirror surface, 9K mirror surface, brushed surface, matte surface. Specification range: 0.03～～5.0mm thick 5.0～～1219mm wide*coil (roll or sheet). Material hardness: Vickers hardness (hv) 160-600 degrees. Hardness status: cold rolled ann(ddq), 1/4h, 1/2h, 3/4h, h, eh, sh.
Sheet: sheet, coil; its surface has bright surface, matte surface, matte surface. Commonly known as stainless steel sheet, 2B sheet, BA sheet. In addition, other light colors can be plated according to customer requirements. The main specifications of the sheet are: 1m* 1m 1m*2m 1.22m*2.44m 1.5m*3m 1.5m*6m, if the customer demand is large, we can cut it according to the customer's size. In addition, we can make drawing boards, anti-skid boards, and electroplating boards.
(3) Stainless steel pipe
Pipes: pipes, seamless pipes, industrial pipes, decorative pipes (seam pipes, welded pipes, welded pipes, bright pipes, longitudinal welded pipes), fluid pipes, hoses, polished pipes; there are more than 200 standard specifications of stainless steel pipes, All sizes, small tubes are more expensive, especially capillary tubes. Capillary tubes are made of 304 material, otherwise the tube is easy to burst. You can also customize non-standard specifications for customers. Seamless tubes are mainly used in industry, and the surface is matte , Not bright. The surface of the seam pipe is a bright surface, and there is a very thin welding line in the pipe, commonly known as a welded pipe, which is mainly used for decorative materials. There are also industrial fluid pipes whose pressure resistance depends on the wall thickness. 310 and 310S are High temperature resistant tube. It can be used normally below 1080 degrees, and the highest temperature can reach 1150 degrees.
The nature of national standard 304 stainless steel sheet
Tensile strength (Mpa) 620 MIN
Yield strength (Mpa) 310 MIN
Elongation (%) 30 MIN
Area reduction (%) 40 MIN
The density of 304 stainless steel is 7.93 g/cm3. Austenitic stainless steel generally uses this value. 304 chromium content (%) 18-20. 304 is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in my country. 304 stainless steel is a universal stainless steel material. Anti-rust performance is stronger than 200 series stainless steel materials. High temperature resistance is also better, as high as 1000-1200 degrees. 304 stainless steel has excellent stainless corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is found in experiments that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration ≤ 65% below the boiling temperature. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
