347 / 1.4550
347 stainless steel is variant of the basic austenitic 18/8 Grade 304 with added Columbium – the introduction of Columbium stabilizes the steel and eliminates carbide precipitation which subsequently causes intergranular corrosion.
The steel has excellent forming and welding qualities and excellent toughness even at cryogenic temperatures.
