304 (UNS S30400)

304 Austenitic Stainless Steel

UNS  S30400


Austenitic stainless steel 304 (UNS S30400) is the standard “18/8” austenitic stainless

and it is the most  versatile and most widely used stainless steel. 304 (UNS S30400) also is a low carbon (0.08% max) version of basic 18-8 also known as 302. It is an economical and versatile corrosion resistant stainless steel suitable for a wide range of general purpose applications with good mechanical properties and strength.Both 304 and 304L are non-magnetic in the annealed condition but may become slightly magnetic as a result of cold working or welding.304L is an extra low-carbon variationof 304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding.Both grades can be used extensively.

304 (UNS S30400) has excellent corrosion resistance in a wide range of media. It resists ordinary rusting in most architectural applications and is also resistant to most food processing environments.And the chemical composition, mechanical properties, weldability and corrosion/oxidation resistance entitles 304 (UNS S30400) the best all-round performance at relatively lower cost.
