Stainless steel is a popular material used in various industries due to its excellent corrosion resistance, high strength, and good ductility. Different countries have their own standards for stainless steel, which cover the chemical composition, mechanical properties, and manufacturing processes. In this article, we will provide a detailed overview of the stainless steel standards used in different countries.

United States: In the United States, ASTM (American Society for Testing and Materials) standards are widely used for stainless steel. Some of the commonly referenced ASTM standards for stainless steel include:

ASTM A240: This standard covers the chemical composition, mechanical properties, and manufacturing processes for flat-rolled stainless steel sheet and strip used in pressure vessels and boilers.

ASTM A480: This standard covers the general requirements for stainless steel bars, forgings, and mechanical tubing.

ASTM A554: This standard covers the mechanical properties and manufacturing processes for welded stainless steel mechanical tubing.

ASTM A790: This standard covers the chemical composition, mechanical properties, and manufacturing processes for seamless and welded stainless steel pipe used in high-temperature service.

European Union: In the European Union, EN (European Norms) standards are used for stainless steel. Some of the commonly referenced EN standards for stainless steel include:

EN 10088: This standard covers the chemical composition, mechanical properties, and manufacturing processes for stainless steel sheet, strip, and plate.

EN 10095: This standard covers the surface quality and tolerances for stainless steel sheet, strip, and plate.

EN 10296: This standard covers the chemical composition, mechanical properties, and manufacturing processes for seamless and welded stainless steel tubes for general applications.

EN 10297: This standard covers the chemical composition, mechanical properties, and manufacturing processes for seamless and welded stainless steel tubes for pressure applications.
