Product Details

Alloy 347/347H Heat Resistant Stainless Steel Plate is a columbium/tantalum  stabilized austenitic chromium-nickel stainless steel.  This material is stabilized against chromium  carbide formation by the addition of columbium and tantalum.

Since these elements have a stronger  affinity for carbon than chromium, columbium-tantalum carbides precipitate  within the grains instead of forming at the grain boundaries.

347 should be considered for applications  requiring intermittent heating between 800ºF (427ºC) and 1650ºF (899ºC) or for  welding under conditions which prevent a post-weld anneal. 347 is non-magnetic.
