[Introduction to our 304 stainless steel pipe and 316L stainless steel pipe] Introduction to 304 stainless steel pipe: It is a kind of high alloy steel that can resist corrosion in the air or chemical corrosion medium. 304 stainless steel pipe is a kind of steel with beautiful surface and good corrosion resistance. It does not need surface treatment such as color plating, but gives play to the inherent surface properties of stainless steel, and is used in many aspects of steel. 304 stainless steel pipe is usually called stainless steel. The representative properties are 13 chrome steel, 18-8 chrome nickel steel and other high alloy steels. From the metallographic point of view, because the stainless steel contains chromium, a very thin chromium film is formed on the surface. This film is separated from the invading oxygen in the steel and plays a corrosion resistant role. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium. 304 is a universal stainless steel, which is widely used to make equipment and parts requiring good comprehensive performance (corrosion resistance and formability). 304 stainless steel is a grade of stainless steel produced according to American ASTM standards. 304 is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China. 304 stainless steel performance: 304 stainless steel is a widely used chromium nickel stainless steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. It is suitable for food processing, storage and transportation. It has good processability and weldability. Use of 304 stainless steel pipe: (1) civil pipe is divided into round pipe, rectangular pipe and flower pipe, which are generally used for decoration, architecture, structure and other aspects; (2) Industrial pipes: steel pipes for industrial piping, steel pipes for general piping (drinking water pipes), mechanical structure/fluid conveying pipes, boiler heat exchange pipes, food hygiene pipes, etc. It is generally used in various industrial fields, such as petrochemical industry, paper making, nuclear energy, food, beverage, and other industries, which have high requirements for fluid media. [Introduction to 316L stainless steel pipe] Chemical composition of 316L stainless steel pipe material% (carbon) C ≤ 0.03 (silicon) Si ≤ 1.00 (manganese) Mn ≤ 2.00 (phosphorus) P ≤ 0.035 (sulfur) S ≤ 0.03 (nickel) Ni: 10.0-14.0 (chromium) Cr: 16.0-18.0 (molybdenum) Mo: 2.0-3.0 Annealing solution state: front row, 2B, N0.4, HL and other surface states 316L is a molybdenum containing stainless steel. Because the steel contains molybdenum, its overall performance is better than 310 and 304 stainless steels. Under high temperature conditions, when the concentration of sulfuric acid is less than 15% or more than 85%, 316L stainless steel has a wide range of uses. 316L stainless steel also has good chloride corrosion resistance, so it is usually used in marine environment. The large carbon content of 316L stainless steel is 0.03, which can be used in applications where annealing cannot be carried out after welding and where greater corrosion resistance is required Use of 316L stainless steel pipe Equipment for pulp and paper making: heat exchanger, dyeing equipment, film processing equipment, pipes, materials used outside buildings in coastal areas, watch chains and watch cases of advanced watches. Equipment for seawater, chemical, dye, paper making, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD poles, bolts, nuts. Now let's take a look at the pictures of our products: This is our company's stainless steel square tube, 304 material, the surface is very smooth, no trachoma, no black spots, no bumps. Luyu Stainless Steel is produced according to the new national standard YB/T5363-2006 Welded Stainless Steel Pipe, in line with the American ASTMA554 and other foreign standards, and reaches the European Union ROHS standard. The quality management is strictly in accordance with the ISO9001: 2000 quality management system. This is our 316L stainless steel round pipe with strong and super corrosion resistance. The construction, chemical industry and shipbuilding equipment in coastal areas are preferred. The weld bead is flat and suitable for assembly. Our stainless steel pipes are made of well extended materials and firmly welded. They are used within the range specified in the standard. Flaring, bending and taper pipes do not crack. 304 (8 nickel and 18 chromium) plate and Baosteel 316L plate are used, which are free of peeling, less trachoma, flexible and bright in surface gloss. 316L stainless steel pipe, the larger carbon content of 00Cr17Ni14Mo2 stainless steel is 0.03, which can be used in applications that cannot be annealed after welding and need greater corrosion resistance Calculation formula of theoretical weight of stainless steel square tube (side width × 4 ÷ 3.14 - thickness) × thickness × 0.02491 (density) Luyu stainless steel is firmly welded with argon arc welding technology and argon gas protection inside. The weld is flat, fully welded, and does not crack when bent. It has good eversion, suitable for flattening, flaring, punching, stretching, bending, etc. The nickel content is stable Stainless steel generally does not suffer from local corrosion. The chloride content that 304 stainless steel can withstand can reach 200ppm, and the chloride content that 316 stainless steel can withstand can reach 1000ppm Our brushed stainless steel square tube is a special stainless steel square tube material for mechanical structure, with a wall thickness of 8.0mm and an outer diameter of 200 × 200 304 stainless steel square tube, the outer diameter can be controlled at plus or minus 0.1mm, the thickness is plus or minus 0.02mm (the precision can be controlled according to customer requirements), the thickness with special requirements can be more accurate, and the inner and outer fittings of the pipe can be more accurate. The stainless steel flat tube has an average four corners and a flat surface without mold marks. In the process of deep processing, the grinding head, cloth wheel, wax, electricity and labor will save costs. 304 stainless steel rectangular tubes are all stainless steel tubes used for hardware products, chemical industry and mechanical equipment, not ordinary decorative tubes, so the wall thickness can be more than 5mm.
