Standard for alloy identification

An ASTM committee on steel, stainless steel and related alloys (A01) is developing a proposed standard that will present a fast-screening framework for verifying the alloys in stainless-steel products.

According to ASTM International member David O’Donnell, portable positive material identification (PMI) devices have become a reliable alternative to more costly methods of determining metal or alloy mixes. Testing per the proposed standard (WK69255) can occur after a piece has been fabricated or at other points in the manufacturing process.

‘Stainless and nickel alloys are all highly recycled materials,’ he said. ‘The proposed practice will help standardize product alloy checking efforts.’
