In practical application of stainless steel coil, the steel resistant to weakly corrosive media is often called stainless steel coil, and the steel resistant to chemical media is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to corrosion by chemical media, while the latter are generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.

 Stainless steel coil is steel that is not easy to rust. In fact, some stainless steels have both stainless and acid resistance (corrosion resistance). The rust and corrosion resistance of stainless steel is due to the composition of a chromium-rich oxide film (passivation film) on the surface. This stainless and corrosion resistance are relative. Experiments have shown that the corrosion resistance of steel in weak media such as the atmosphere and water and oxidizing media such as nitric acid improves with the addition of chromium water content in steel. When the chromium content reaches a certain percentage, the corrosion resistance of steel occurs Sudden change, from easy to rust to not easy to rust, from non-corrosion to corrosion resistance. There are many classifications of stainless steel coil. |
According to the arrangement structure at room temperature, there are martensitic, austenitic, ferritic, and duplex stainless steels. According to the classification of the main chemical components, they can basically be divided into two major systems: chromium stainless steel coil and chromium-nickel stainless steel coil. There are nitric acid-resistant stainless steel, sulfuric acid-resistant stainless steel, seawater-resistant stainless steel, etc., which can be divided into pitting-resistant stainless steel, stress-resistant stainless steel, and intergranular stainless steel according to the type of corrosion resistance; Magnetic stainless steel, free cutting stainless steel, low temperature stainless steel, high strength stainless steel and so on. Because stainless steel has a series of characteristics such as excellent corrosion resistance, formability, compatibility, and strong resistance over a wide temperature range, it has been widely used in heavy industry, light industry, daily life occupations, and building decoration occupations . |
Austenitic stainless steel coil have austenitic arrangements at room temperature. When steel contains about 18% Cr, Ni 8% ~ 10%, and C about 0.1%, it has a stable austenite arrangement. Austenitic chromium-nickel stainless steel contains the well-known 18Cr-8Ni steel and high Cr-Ni series steels developed by adding Cr and Ni content and participating in the development of Mo, Cu, Si, Nb, Ti and other elements. Austenitic stainless steel is non-magnetic and has high resistance and plasticity, but its strength is low. It cannot be strengthened by phase transformation. It can only be strengthened by cold working. Such as participation in S, Ca, Se, Te and other elements, it has outstanding machinability. In addition to corrosion resistance of oxidizing acid media, this type of steel can also be corrosive to sulfuric acid, phosphoric acid, and acetic acid and urea if it contains elements such as Mo and Cu. If the carbon content in this kind of steel is less than 0.03% or contains Ti and Ni, it can significantly improve its resistance to intergranular corrosion. |
| Surface Finish | Characteristics and application |
| 2B | The surface brightness and flatness of NO.2B is better than NO.2D. then through a special surface treatment to improve its mechanical properties,No.2B could nearly satisfy comprehensive uses. |
| NO.1 | Polished with abrasive belt of grit#100-#200, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc. |
| NO.4 | Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria, but thinner than No.3, are used as bathtub buildings inner and external ornaments electrical appliances kitchen utensils and food processing equipment etc. |
| HL | Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streaks, mainly used as buildings ornaments elevators, door of building, frontal plate etc. |
| BA | Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus, ornament etc. |
| 8K | The product have excellent brightness and prefer reflexivity can to be the mirror. |
