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
