304 Stainless Steel Pipe is the standard “18/8” stainless steel; 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 steel part such as sink, hollow-ware and saucepan. For these application it is common to use special “304DDQ” (Deep Drawing Quality) variants. Grade 304 Pipe is readily brake or roll formed into a variety of components for application in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristic. Post-weld annealing is not required when welding thin sections. Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge component (over about 6mm). Grade 304H with its…

ASME SA 213 / ASTM A213 304 stainless steel tube is a variation of the 18% chromium – 8% nickel austenitic stainless steel tube, the most familiar and most frequently used alloy in the stainless steel family. This stainless steel be considered for a wide variety of application on good corrosion resistance, ease fabrication, excellent formability, and high strength with low weight. 304 Stainless Steel Tube is the standard “18/8” stainless steel; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other.
