304 Stainless Steel Pipe/Tube, Flanges, Fittings

Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively. Type 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel.

304 stainless steel bar, also known as UNS S30403 and Grade 304, is the low carbon content version of Type 304 generally preferred because it is the "free machining" version. Grade 304 exhibits good combination of strength and corrosion resistance making it ideal for almost all industries. Cold working will increase both the hardness and strength, and it does not respond to heat treatment.

The stainless austenitic chromium-nickel steel 1.4301 shows good corrosion resistance (particularly in natural environmental media and in the absence of considerable chlorine and salt concentrations and sea water) and weldability. Application with acids have to be checked individually. However, after welding 1.4301 is not stable to intergranular corrosion. Good polishing and deep drawing property. It is used in the crude oil industry, chemical industry, petrochemical industry, automobile industry
