　　Jawaysteel-Focus on stainless steel products for 20 years. We can product stainless steel wire, spring wire micro wire, hydrogen annealing wire, bright wire, medium soft wire, cold forging wire, electrolytic, welding wire, Gas-shielded welding wire, semiautomatic welding wire, straight strip welding wire, submerged are welding wire, straight rod, black rod, acid rod, bright rod, angle bar, flat bar, and channel bar. Of course, the special stainless steel and stainless iron also could be made to order. Our stainless steel cover the grade of 207, 201, 202, 301, 302, 303, 304, 304L etc. Our company think it is our spirit that self-esteem, self-confidence and mutual benefit. Let's talk about stainless steel.

　　What's stainless steel?

　　Generally speaking, stainless steel is not easy to rust steel, in fact, some stainless steel, both rust resistance and acid resistance (corrosion resistance). Stainless steel rust and corrosion resistance is due to the formation of chromium-rich oxide (passivation film) on the surface. This rust resistance and corrosion resistance are relative. The results show that the corrosion resistance of steel increases with the increase of chromium content in air, water and oxidizing medium such as nitric acid. When chromium content reaches a certain percentage, the corrosion resistance of steel changes. That is, from easy rust to not easy to rust, never corrosion to corrosion.

　　Type of stainless steel?

　　stainless steel is usually divided into martensite steel, ferrite steel, austenitic ferrite (dual phase) stainless steel and precipitated hardened stainless steel. In addition, according to the composition can be divided into: chromium stainless steel, chromium-nickel stainless steel and chromium-manganese nitrogen stainless steel and so on. There is also a special stainless steel for pressure vessels & stainless steel plates and strips for use in GB24511_2009_ pressure equipment.

　　Main characteristics of stainless Steel?

　　1.weldability

　　Different uses of the product requirements for welding performance are also different. A type of tableware generally does not require welding performance, including even some pot enterprises. But most products need good welding performance, such as class II tableware, insulation cup, steel pipe, water heater, water dispenser and so on.

　　2.corrosion resistance

　　The vast majority of stainless steel products require good corrosion resistance, such as first and second class utensils, kitchenware, water heaters, water dispensers, etc. Some foreign businessmen have also done corrosion resistance tests on the products: heated to boiling with NACL aqueous solution, Remove solution after a period of time, wash and dry, weight loss, to determine the degree of corrosion (note: the product polishing, because the sand cloth or sandpaper containing Fe composition, will lead to the test surface rust)

　　3.Polishing performance

　　In today's society, stainless steel products are generally polished by this process, only a small number of products such as water heater, drinking machine liner and so on do not need polishing.

　　1) surface defects of raw materials. Such as scratches, pockmarks, pickling, etc.

　　2)Material quality of raw materials. When the hardness is too low, the polishing process is not easy to be polished (BQ property is not good), and the hardness is too low. The orange peel is easy to appear on the surface during deep drawing, which affects the BQ property. BQ with high hardness is relatively good.

　　3)After deep drawing, small black spots and RIDGING will appear on the surface of the area with great deformation, which will affect the BQ property.

　　In the 20 years of this development, Jawaysteel has made friends from all over the world and finally became a good friend. We use the highest product quality and the best service to keep customers in the shoes. Please feel free to contact us.
