What types of materials are 20# steel, stainless steel 06CRr19Ni10, and low-temperature steel A333 respectively? Is it carbon steel, low-alloy structural steel, or low-alloy high-strength steel with special properties?

20 steel is a low-carbon carbon steel; 06CRr19Ni10 stainless steel is the name given in national standards to 304 stainless steel, and it is a nickel-chromium steel that is widely used. A333Gr6 is a nickel-free steel for low-temperature applications

These three types of steel all belong to ferrous metals, which are divided into four categories: carbon structural steel, low-alloy structural steel, cast steel and cast iron, and low-alloy high-strength steel with special properties.
