309S 2B Stainless Cold Rolled Coils is a free cutting stainless steel containing sulfur, used for the main requirements of free cutting and high surface finish. 309S corresponding Chinese brand is 0Cr23Ni13, American standard S30908(American AISI, ASTM) characteristics and uses: corrosion resistance, heat resistance are better than 0Cr19Ni9. The 309s is a variant of the lower carbon 309 stainless steel for use where welding is required. The lower carbon content minimizes the carbide precipitation in the heat-affected zone near the weld, which may lead to intergranular corrosion (welding erosion) of stainless steel in some environments. It can withstand repeated heating below 980 ℃, and has high high temperature strength, oxidation resistance and carburizing resistance. Widely used in boiler, energy (nuclear power, thermal power, fuel cell), industrial furnace, incinerator, heating furnace, chemical industry, petrochemical and other important fields.

316L 2B Stainless Cold Rolled Coils is often used in pulp and paper equipment heat exchanger, dyeing equipment, film washing equipment, pipeline, coastal area building external materials, as well as senior watch chain, case, etc. Seawater equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts. Cold rolled products good appearance gloss, beautiful; Due to the addition of Mo, excellent corrosion resistance, especially pitting resistance, excellent high temperature strength, excellent work hardening (weak magnetism after processing. Solid solution state no magnetism, relative 304 stainless steel, high price.

321 2B Stainless Cold Rolled Coils is Ni-Cr-Ti austenitic stainless steel, with abrasion resistance, high temperature resistance, creep resistance, etc., used in the manufacture of wear-resistant acid containers and wear-resistant equipment lining, conveying pipeline. 321 stainless steel has good abrasion resistance in organic and inorganic acids of different concentrations and temperatures, especially in oxidizing media, and is used for the manufacture of wear-resistant acid containers and wear-resistant equipment lining, conveying pipeline. Due to the addition of titanium metal, it effectively controls the formation of chromium carbide. 321 stainless steel has a better Stress Rupture performance and a higher temperature Creep Resistance in both stress and mechanical properties than 304 stainless steel. Suitable for welding components at high temperature. Used in chemical, coal and petroleum industries with high corrosion resistance to grain boundaries, outdoor machines, heat-resistant parts of building materials and parts with difficulty in heat treatment.

304L 2B Stainless Cold Rolled Coils，also known as ultra-low carbon stainless steel, is a kind of universal stainless steel material, widely used in the production of good comprehensive performance (corrosion resistance and formability) of equipment and parts. 304 l stainless steel is one of the austenitic stainless steel material, also is low carbon stainless steel.The carbon content of 304 l stainless steel is low, less than 0.03%, is a stainless steel varieties derived from 304 stainless steel, mainly used for occasions need welding. 304 l stainless steel with low carbon content for the intergranular corrosion resistant ability, even if the welding can maintain the good corrosion resistance.

304 2B Stainless Cold Rolled Coils: 304 stainless steel coil steel coil, also known as coil steel. Steel is molded into coils by hot and cold pressing. In order to facilitate storage and transportation, it is convenient to carry out various processing (such as processing into steel plates, steel strips, etc.).  304 stainless steel is a common material in stainlessstainless steel,High temperature 800℃, with good processing performance, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry. 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).

301 2B Stainless Cold Rolled Coils is a kind of metastable austenitic stainless steel, under the condition of full solid solution, with complete austenitic structure. 301 is mainly used in cold working state for equipment parts that bear high loads and want to reduce equipment weight and not rust. In addition, this steel is easy to produce work hardening when impacted by external force, which can absorb more impact energy and provide more reliable safety guarantee for equipment and personnel. 301 is prone to work hardening during deformation, and is used in places requiring high strength.

202 2B Stainless Cold Rolled Coils stainless steel plate belongs to the stable Austenite system stainless steel, its national standard model is 1Cr18Mn8Ni5N, has high strength, toughness, high wear resistance and has a large work hardening. 202 stainless steel is widely used in architectural decoration, hotel facilities, shopping malls, glass handrails, public facilities and other places. By high-precision automatic pipe making equipment, through its own corrosion solution welding, roll forming, without any metal filler, filled with gas protection (inside and outside the pipe) welding, welding method for TIG process, and online solid solution eddy current inspection.

201 2B Stainless Cold Rolled Coils Stainless steel 201 material is 17Cr-4.5Ni-6Mn-N, is a section of Ni steel. 201 stainless steel, has a certain acid resistance, alkali resistance, high density, polishing no bubbles, no pinhole and other characteristics, is the production of a variety of watchcase, watchband cover quality materials. Mainly used for decorative pipe, industrial pipe, some shallow tensile products.

Commonly used in the steel industry, different from hot-rolled coils. It refers to the steel strip that is directly rolled into a certain thickness with a roll at room temperature and rolled into a full coil with a winder.
