This standard establishes definitions, guidelines, and requirements governing materials (e.g., alloy and heat treat condition) allowed for use in chemical process test specimens when requirements call for a generic class of alloy.
AS2390A results from a Five-Year Review and update of this specification which clarifies Application (1.2), clarifies corrosion and HE in Background (1.3.b and 1.3.b), separates austenitic from martensitic, ferritic, and PH grades in Corrosion Resistant Steel (3.2), removed commercial pure aluminum from Aluminum Alloys (3.7), added commercial pure copper to Copper Alloys (3.7), and added commercial pure titanium to Titanium Alloys (3.8).
