1.4301 square austenitic stainless steels, which have a very suitable combination in terms of forming, mechanical properties and corrosion resistance, constitute approximately 70-80% of stainless steel production in terms of usage area and alloy variety. These alloys feature high toughness and high strength values in a wide temperature range and show good resistance to oxidation at temperatures up to 540 ° C. Austenitic chrome-nickel stainless steels are generally used in humid environments. The most common austenitic stainless steel type is 300 series alloys such as 304 and 316 types. 1.4301 eustenitic stainless steels have a wide range of applications due to their superior properties. Aircraft industry, panels, fuel pipes, wires, tanks in the chemical industry, pipes: condensers, milk tanks, transport tanks, fermentation vessels in the food industry mixers, bottling machines, boiling pots, pharmacy, chemistry and petrochemical, computer keys springs and architecture.

Weldability
Fusion welding performance for 304 square stainless steel is excellent both filled and unfilled. Recommended filler bars and electrodes for 304 square stainless steel are 308 stainless steel. Recommended filler for 304L is 308L. Heavily welded sections may require post-weld annealing. This step is not required for 304L. If post-weld heat treatment is not possible, 321 grade stainless steel can be used.
