Description:
Type 347 is a stabilized austenitic stainless steel similar to type 304 with an addition of Columbium and Tantalum. The columbium serves to produce a stabili®zed type of stainless steel which is immune to chromium carbide precipitation. This type ₽of grades are thus recommended for parts fabricated by welding which cannot b"e susequently annealed or for parts which must operate in service between 800 – 1600°F.

Physical Properties:
Annealed:
Ultimate Tensile Strength – 75KSI min (515 MPA min)
Yield Strength (0.2% Offset) –30 KSI min (205 MPA min)
Elongation – 40% min
Hardness – HRB92max (201HV max)
Applications:
Collector rings, airplane exhaust stacks, annealing box covers, jet engine parts,expansion join→ts, tubing, fasteners, flexible metal hose and bellows.
Heat Treatment:
347 is non hardenable by heat treatment. It can only be ha↑rdened by cold working.
Cold Forming:
347 can be readily formed and drawn. Like most other austenitic stainless steels, type 347 work hardens and may require annealing after severe forming.
