Revision of A453/A453M-17 Standard Specification for High-Temperature Bolting, with Expansion Coefficients Comparable to Austenitic Stainless Steels


Currently A453 does not include evaluation of microstructure. While it is true that microstructure evaluation is often not required by the purchaser, it is also true that failures due to incorrect microstructure can occur. This revision adds a supplemental requirement for microstructure.
