ASTM 304 , 304 Stainless Steel ,ASTM 304 Steel

ASTM Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics.

The balanced austenitic structure of ASTM 304 Stainless Steel enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants.

ASTM 304 Stainless Steel is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 Stainless Steel also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
