Description
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.
Our product range in 1.4301 are tubes and pipes, fittings and flanges, accessories
