1. Chemical analysis (as per SA516 GR70 and SB443 N06625 Standard )

Cladding Metal—The nickel or nickel-base alloy cladding metal specified shall conform to the requirements as to chemical composition prescribed for the respective metal.

Base Metal—The base metal shall be carbon steel or low-alloy steel conforming to the ASTM specifications for steels for either pressure vessels or general structural applications. The base metal shall conform to the chemical requirements of the specification to which it is ordered.
