Description:
347 is an austenitic stainless steel with a stabilizing niobium/columbium addition.
The material is with Good general corrosion resistance, Excellent resistance to intergranular corrosion in the welded condition, Easy to weld and form, Good low temperature toughness.
This grade is austenitic in the solution annealed condition (1000 - 1100°C / 1832 - 2012°F) and rapid cooling by
air or water. It contains a small amount of ferrite and niobium/columbium carbonitrides.
347H is also available.
