Supply of 304 stainless steel sheet 316 stainless steel light board Wholesale

Products stainless steel surface processing grade raw surface: NO.1 hot rolled, annealed and pickled surface. Generally used for cold rolled material, industrial tanks, chemical plant, etc., the thicker the 2.0MM-8.0MM. Blunt surface: NO.2D cold rolling after heat treatment, pickling, its material is soft, silvery sheen surface for deep drawing process, such as automotive components, pipes and so on. Matte: NO.2B cold rolling after heat treatment, pickling, and then to finish processing the surface of the light as a moderate person. Since the surface is smooth, easy to re-grind, make more bright surface, widely used, such as utensils, building materials. Using improve the mechanical properties of the surface treatment, meet almost all purposes. NO.3 with a No. 100-120 grit abrasive belt grinding out product. It has better brightness with discontinuous coarse grain. For building exterior decoration materials, electrical appliances and kitchen equipment. Sand: NO.4 with 150-180 grit abrasive belt grinding out product. It has better brightness with discontinuous coarse grain, thin stripes than NO.3. For baths, both inside and outside the building decoration materials, electrical products, kitchen equipment and food equipment. # 320 with abrasive belt grinding out 320 products. It has better brightness with discontinuous coarse grain, thin stripes than NO.4. For baths, interior and exterior building materials, electrical appliances, kitchen equipment and food equipment. Bristle surface HAIRLINE: HLNO.4 duly continuous grinding belt size polishing abrasive pattern generation product (subdivision number 150 to 320). Mainly used for architectural decoration, elevators, building door panels. Bright side: BA impose bright annealed after cold rolling, and after formation of the resulting product. Excellent surface gloss, has a high reflectivity. As the surface of the mirror. For home appliances, mirrors, kitchen equipment, decorative materials. Product attributes 200 Series: chromium - manganese - nickel austenitic stainless steel 300 Series: chromium - nickel austenitic stainless steel 301: scalability, for molding products. It can also be rapidly hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel. 302: 304 with corrosion resistance, due to relatively high carbon intensity and therefore better. 303: by adding a small amount of sulfur and phosphorus to more than 304 cutting. 304: commonly used models, namely 18/8 stainless steel. GB grades 06Cr19Ni10.309: 304 better than temperature resistance, temperature resistance up to 980 ℃. 310: excellent high-temperature oxidation resistance, the maximum temperature 1200 ℃. 316: Following the 304, the second most widely used of steel, mainly used in the food industry, watches jewelry, pharmaceutical and surgical equipment, adding Mo to obtain a special corrosion-resistant structure. Better than the 304 because of its resistance to chloride corrosion and thus as "marine steel" to use. SS316 is often used to fuel recovery. 18/10 grade stainless steel is usually in line with the application level. 321: In addition to adding titanium as reducing the risk of corrosion of the weld material, other properties are similar to 304.347: add stabilization element niobium, suitable for welding aviation appliance parts and chemical equipment. 400 Series: ferritic and martensitic stainless steel. 408: heat resistance, low corrosion resistance, 11% Cr, 8% of Ni. 409: the cheapest model (England), commonly used as automobile exhaust pipe, is a ferritic stainless steel (chrome steel). 410: martensitic (high-strength chrome steel), good wear resistance, corrosion resistance is poor. 416: Adding sulfur to improve the processing performance of materials. 420: "cutting class" martensitic steel, similar to Brandt's first high-chromium stainless steel this. Also used in surgical tools, you can do very light. 430: ferritic stainless steel, decorative, such as for car accessories. Good shape, but heat resistance and corrosion resistance worse. 440: high strength cutting tool steel, carbon slightly higher, after appropriate heat treatment to obtain a higher yield strength and hardness up to 58HRC, are among the most hard stainless steel. The most common application example is the "razor blades." There are three common models: 440A, 440B, 440C, in addition 440F (and easy processing). 500 Series: heat-resistant chromium alloy steel. 600 Series: martensitic precipitation hardening stainless steel. 630: The most common type of precipitation hardening stainless steel models, usually called 17-4; 17% Cr, 4% Ni. Functional use of stainless steel (Stainless Steel) refers to the resistance of air, steam, water and other corrosive medium and weak acid, alkali, salt and other chemical etching medium corrosion of steel, also known as acid-resistant stainless steel. Practical applications, often the weak corrosion resistance as stainless steel corrosion media, while the chemical resistance of steel known as acid corrosion of steel. As the two differences in the chemical composition, the former does not necessarily chemical resistance corrosion, while the latter generally has a stainless steel sex. Corrosion resistance of stainless steel depends on the alloying elements contained. Stainless basic alloying elements nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet the various uses of stainless steel organization and performance requirements. Stainless steel is easy to be chlorine ion etching, as chromium, nickel, chlorine is the same place the original elements, with the position of the original elements can be interchanged to form a corrosion of stainless steel assimilation. Other notes to increase the corrosion resistance of stainless steel with carbon content is reduced, and therefore, most of the volume low carbon stainless steel, the maximum does not exceed 1.2%, and some steel Wc (carbon content), and even less than 0.03% ( As 00Cr12). Stainless steel is the main alloying elements Cr (chromium), only when the Cr content reaches a certain value, only the corrosion resistance of the steel. Therefore, stainless steel is generally Cr (chromium) content of at least 10.5%. Stainless steel further contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
