In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchenware.    It has the following characteristics:  1. Weldability    Different product uses have different requirements for welding performance. A class of tableware generally does not require welding performance, and even includes some pot enterprises. However, most products require good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.2. Corrosion resistance   Most stainless steel products require good corrosion resistance, such as Class I and II tableware, kitchen utensils, water heaters, water dispensers, etc. Some foreign merchants also do corrosion resistance tests on the products: use NACL aqueous solution to heat it to boiling, and pour it after a period of time. Remove the solution, wash and dry, and weigh the weight loss to determine the degree of corrosion (Note: When the product is polished, the Fe content in the abrasive cloth or sandpaper will cause rust spots on the surface during the test)3. Polishing performance   In today's society, stainless steel products are generally polished during production, and only a few products such as water heaters and water dispenser liner do not need polishing. Therefore, this requires that the polishing performance of the raw material is very good. The main factors that affect the polishing performance are as follows:(1)Surface defects of raw materials. Such as scratches, pitting, pickling, etc.(2)The problem of raw materials. If the hardness is too low, it will not be easy to polish when polishing (the BQ property is not good), and if the hardness is too low, the orange peel phenomenon is easy to appear on the surface during deep drawing, thus affecting the BQ property. BQ properties with high hardness are relatively good.(3)For the deep-drawn product, small black spots and RIDGING will appear on the surface of the area with a large amount of deformation, thus affecting the BQ performance.4. Heat resistance   Heat resistance means that stainless steel can still maintain its excellent physical and mechanical properties at high temperatures.Influence of carbon: Carbon is an element that strongly forms and stabilizes austenite and expands the austenite region in austenitic stainless steels. The ability of carbon to form austenite is about 30 times that of nickel, and carbon is an interstitial element that can significantly increase the strength of austenitic stainless steel through solid solution strengthening. Carbon can also improve the stress  corrosion resistance of austenitic stainless steel in highly concentrated chloride (such as 42% MgCl2 boiling solution).Product ParametersProduct nameStainless Steel PipePlace of OriginShandong, ChinaBrand NameZhong HengApplicationDecoration, Kitchen, etc.ThicknessAs your requirementStandardJIS, ASTM EN JIS DIN GBProcessing ServiceBending, Welding, Decoiling, Punching, CuttingMOQ1 TonSurfaceBA/2B/NO.1/NO.3/NO.4/8K/HL/2D/1DColorCustimizedPayment30%TT+70%TTShapeFlat, Sheet, Coil, PlateMaterial GradeTP304 TP304L TP316 TP316L TP347 TP347H TP321 TP321H TP310 TP310STP410 TP410S TP403S31803/S32205 S32750 S32760Outer DiameterSeamless Pipe: 4mm-812.80mmWelded Pipe: single slit(Φ8mm-Φ630mm); girth(Φ630mm-Φ3000mm),ThicknessSeamless Pipe: 0.5mm - 60mmWelded Pipe: single slit(0.5mm-25mm);girth(3mm-45mm)Length5.8-6.1 m or as customers' requestToleranceAcording to the Standard.Surface180G, 320G, 400G Satin / Hairline400G, 500G, 600G or 800G
