Cold Rolled/Hot Rolled/ Cold Rolled Steel Round Black Steel Pipe 
304 Stainless Steel 304 is a versatile stainless steel that is widely used to make equipment and parts that require good overall performance(corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel.

316 stainless steel 316 stainless steel has excellent corrosion resistance, atmospheric corrosion resistance, and high-temperature strength due to the addition of Mo, which can be used under harsh conditions; excellent work hardening (non-magnetic). Equipment for seawater use,chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; photographs, food industry, facilities incoastal areas, ropes, CD rods, bolts, nuts.

430 stainless steel Type 430 Stainless Steel is perhaps the most popular non-hardenable ferritic stainless steel available. Type 430 is known for good corrosion, heat, oxidation resistance, and its decorative nature.It is important to note that when well polished or buffed its corrosion resistance increases. All welding must occur at higher temperatures, but it is easily machined, bent, and formed. Thanks to this combination it is used in a number of different commercial and industrial applications including:Furnace combustion chambers,Automotive trim and molding,Gutters and downspouts, plant equipment,Oil and Gas refinery equipment,Restaurant equipment,Dishwasher linings,Element supports and fasteners.etc.
 

J1(Mid Copper): The carbon content is slightly higher than J4 and the copper content is lower than J4. Its processing performance is less thanJ4. It is suitable for ordinary shallow drawing and deep drawing products, such as decorative board, sanitary products, sink,product tube, etc.

J2, J5:Decorative tubes: Simple decorative tubes are still good, because the hardness is high (both above 96°) and the polishing is morebeautiful, but the square tube or the curved tube (90°) is prone to bursting. In terms of flat plate: due to the high hardness, the board surface is beautiful, and the surface treatment such as frosting,polishing and plating is acceptable. But the biggest problem is the bending problem, the bend is easy to break, and the groove is easy to burst. Poor extensibility.

J3(Low Copper): Suitable for decorative tubes. Simple processing can be done on the decorative panel, but it is not possible with a little difficulty. There is feedback that the shearing plate is bent, and there is an inner seam after breaking (black titanium,color plate series, sanding plate, broken, folded out with inner seam). The sink material has been tried to bend, 90 degrees, but it will not continue.

J4( High Copper): It is the higher end of the J series. It is suitable for small angle types of deep drawing products. Most of the products that require deep salt picking and salt spray test will choose it. For example, sinks, kitchen utensils, bathroom products, water bottles, vacuum flasks, door hinges, shackles, etc
