What is ASTM A213 Type 304?
ASTM A213 TP304 specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Heat-Exchanger and Superheater Tubes. ASTM A213 seamless Tube mostly used as superheater, boiler, heat exchanger tubes.
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 Grade 304 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. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
The only difference between them is the carbon content. Type 304 has a maximum carbon of 0.07% . Type 304L has maximum carbon of 0.030 %. This range of carbon in the steels affects the corrosion resistance.
