Tolerance: ±0.05 mm
Features: Stainless steel is steel that is not easy to rust. In fact, some stainless steels have both rust and acid resistance (corrosion resistance).
Expansion: The stainless steel's rust and corrosion resistance is due to the formation of a chromium-rich oxide film (passivation film) on its surface. This rust and corrosion resistance are relative. The test shows that in the weak medium such as atmosphere and water and the oxidizing medium such as nitric acid, the corrosion resistance of the steel increases with the increase of the water content of the chromium in the steel. When the chromium content reaches a certain percentage, the corrosion resistance of the steel changes suddenly. From rust to rust, from corrosion resistance to corrosion resistance.. There are many ways to classify stainless steel. Classified according to the structure of the room temperature, there are martensite, austenitic, ferrite and duplex stainless steel; according to the main chemical composition, can be divided into two major systems: chromium stainless steel and chromium nickel stainless steel; There are nitric acid resistant stainless steel, sulfuric acid resistant stainless steel, seawater resistant stainless steel, etc. According to the type of corrosion resistance, it can be divided into pitting resistant stainless steel, stress corrosion resistant stainless steel, intergranular corrosion resistant stainless steel, etc. Magnetic stainless steel, free-cutting stainless steel, low-temperature stainless steel, high-strength stainless steel, etc. Due to its excellent corrosion resistance, formability, compatibility and toughness over a wide temperature range, stainless steel is widely used in heavy industry, light industry, household goods industry and architectural decoration industries. . Due to the high price of stainless steel, stainless steel is not currently used in the manufacture of automotive casings, but we can still use stainless steel for the inner parts.
