316L NO.1 Stainless Hot 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 NO.1 Stainless Hot 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 is Ni-Cr-Ti austenitic stainless steel, its performance is very similar to 304, but because of the addition of titanium metal, it has better resistance to grain boundary corrosion and high temperature strength. 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 NO.1 Stainless Hot 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 NO.1 Stainless Hot Rolled Coils is a common material in stainless 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). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium and more than 8% nickel content.

301 NO.1 Stainless Hot 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 NO.1 Stainless Hot Rolled Coils 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 N0.1 Stainless Hot Rolled Coils 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.

316 2B Stainless Cold Rolled Coils, 18Cr-12Ni-2.5Mo due to the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used under harsh conditions; Excellent work hardening (non-magnetic). Seawater equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts. Chemical composition of 316 stainless steel :C≤0.08, Si≤1.00, Mn≤2.00, P≤0.035, S≤0.03, Ni:10.0-14.0, Cr:16.0-18.5, Mo:2.0-3.0. Mechanical properties of 316 stainless steel, tensile strength (Mpa) 620 MIN, yield strength (Mpa) 310 MIN, elongation (%) 30 MIN, area reduction (%) 40 MIN, density of 316 stainless steel 8.03 g/cm3

630 stainless steel is martensitic precipitation-hardened stainless steel.630 stainless steel properties are easy to adjust the strength level, can be adjusted by changing the heat treatment process, martensitic phase transformation and aging treatment to form precipitation-hardened phase is the main means of strengthening, 630 stainless steel has good attenuation performance, corrosion fatigue and water drop resistance. Applications: offshore platforms, helicopter decks, food industry, pulp and paper industry, aerospace (turbine blades), mechanical components, nuclear waste drums.
