304 stainless steel pipe is a stainless steel pipe made from iron, chromium, and nickel alloy. Silver Tubes is a known manufacturer of Stainless Steel 304 Pipes, a variation of the basic 18-8 grade, with higher chromium and lower carbon content. SS 304 Pipes are non-hardenable by heat treatment. Annealing: Heat to 1900 Degrees F – 2050 Degrees F (1038 Degrees C – 1121 Degrees C), then cool rapidly. 304 Stainless Steel Pipes have excellent draw ability, where a grouping of low yield power and high elongation allows an effective forming of multifaceted shapes. 304 Welded Pipes are generally weldable by the common fusion and resistance. The strip sections in 304 EFW Pipes may be air-cooled, but heavy sections should be water-quenched to minimize exposure in the carbide precipitation region.
