National steel standards are country-specific frameworks that define the chemical composition, mechanical properties, testing methods, and certification requirements for steel products. Standards such as ASTM (USA), BS (UK), DIN (Germany), JIS (Japan), IS (India), and GOST (Russia) ensure uniform quality, safety, and performance across industries. These national guidelines help engineers, buyers, and manufacturers select the right steel grade for strength, durability, and regulatory compliance, making material selection more accurate and reliable.
The customer requirements are based on the expected use of the standard. The first consideration of any material standard is to make a supplier-independent specification of the material. Material from a certain grade must behave in a similar way regardless of the supplier. When the materials are heat-treated or subjected to various service conditions such as heat, cold or corrosive environments, the properties are affected. These effects depend on the chemical composition of the material. If the manufacturers are allowed to decide the composition of the material freely, unexpected differences in behavior between grades may occur.
