Aisi And Astm Type 347 Stainless Steel Sheet Coil

347 stainless steel properties

347 stainless steel 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.

# Product Transportation

The steel strips supplied according to the standard are usually applied with common rustproof oil film, which can be swept away with alkali solution. The supplier guarantees that the oiled products will be free from rust under normal packing, transportation, loading and storage conditions within 6 Months, the approved delivery date. However, product without oil coating can also be subject subject to statement in the contract reached after discussion between the user and the supplier.
