0Cr18Ni9, also known as 1Cr18Ni9, is a stainless steel with a long history. The "0 Cr18Ni9" or "1Cr18Ni9" in its name indicates the main alloying element of the stainless steel and its approximate content, of which the content of Cr (chromium) is about 18% and the content of Ni (nickel) is about 9%. This stainless steel has good stability in oxidizing acid, in order to obtain the austenitic structure at room temperature, it is necessary to add a certain proportion of nickel element.
GB4237/4238 0Cr18Ni9 stainless steel features:
Corrosion resistance and high temperature properties: 0Cr18Ni9 stainless steel has excellent corrosion resistance and high temperature properties, and can resist the erosion of most acids, alkalis, salts and other chemicals.
Mechanical properties: The stainless steel has good tensile strength, making it capable of manufacturing parts and structures in structural engineering.
Surface characteristics: It is not easy to rust, smooth surface, with a silver-white appearance, which makes it in architectural decoration, kitchen utensils and jewelry and other fields have a wide range of appearance design applications. In addition, its materials meet hygiene standards and are particularly suitable for equipment in the food and pharmaceutical industries.
GB4237/4238 0Cr18Ni9 stainless steel chemical composition:
