Foldable weldability Different uses of products have different requirements for welding performance. A class of tableware welding performance generally do not do requirements, even including part of the pot enterprises. But the vast majority of products need raw materials with good welding performance, such as second-class tableware, thermos cup, steel pipe, water heater, water dispenser and so on. Folding corrosion resistance The vast majority of stainless steel products require good corrosion resistance, such as one or two types of tableware, kitchenware, water heater, water dispenser, etc., some foreign businessmen also do corrosion resistance tests on products: with NACL water solution heating to boiling, after a period of time to dump the solution, wash and dry, weight loss, to determine the degree of corrosion. Folding polishing property In today's society, stainless steel products are generally polished in the production of this process, only a few products such as water heaters, water dispensers and so on do not need polishing. Therefore, this requires the material polishing performance is very good. The main factors affecting polishing properties are as follows: ① Surface defects of raw materials. Such as scratches, pitting, pickling, etc. ② The problem of raw materials. The hardness is too low, it is not easy to polish when polishing (BQ is not good), and the hardness is too low, the surface is easy to appear orange peel phenomenon when deep stretching, thus affecting the BQ property. High hardness BQ sex is relatively good. (3) After deep stretching, small black spots and RIDGING will appear on the surface of the area with great deformation, which will affect the BQ property. Folding heat resistance Heat resistance refers to the high temperature stainless steel can still maintain its excellent physical and mechanical properties.

Stainless steel finish grade Original surface :NO.1 hot rolled surface subjected to heat treatment and pickling treatment. Generally used for cold rolling materials, industrial tank, chemical industrial equipment, thickness from 2.0MM-8.0MM. Blunt surface :NO.2D cold rolling after heat treatment, pickling, its material is soft, the surface is silver luster, used for deep stamping processing, such as automobile components, water pipes, etc. Fog surface :NO.2B cold rolling after heat treatment, pickling, and then finish rolling processing to make the surface for moderate brightness. Because the surface is smooth, easy to grind, make the surface more bright, widely used, such as tableware, building materials and so on. With improved mechanical properties of the surface treatment, almost all applications. Coarse sand NO.3 with No. 100-120 grinding belt grinding out the product. Has a better gloss, with discontinuous coarse grain. Used for interior and exterior decoration materials, electrical products and kitchen equipment, etc. Fine sand :NO.4 with particle size 150-180 grinding belt grinding product. Better gloss, with discontinuous coarse lines, stripes thinner than NO.3. Used for bath, building inside and outside decorative materials, electrical products, kitchen equipment and food equipment, etc. #320 Grinding product with No. 320 grinding strip. Better gloss, with discontinuous coarse lines, stripes thinner than NO.4. Used for bath, interior and exterior decoration materials, electrical products, kitchen equipment and food equipment, etc. HLNO.4 is continuously ground with the appropriate size polishing belt to produce the product of grinding pattern (subdivision 150-320). Mainly used for architectural decoration, elevator, building doors, panels and so on. Bright surface :BA after cold rolling subjected to bright annealing, and through the smooth product. Excellent surface gloss and high reflectivity. A mirror-like surface. Used in household appliances, mirrors, kitchen equipment, decorative materials, etc.
