Alloy 347H is the higher carbon variant of the alloy, enabling enhanced creep resistance and for higher strength at temperatures above 537°C.
Stainless steel Grade 347 is similar to grade 321, but with slightly improved corrosion resistance in strongly oxidizing environments. Stainless steel 347 is essentially non-magnetic in the annealed condition and can only be hardened by cold working.
