Cromgard generally conforms to ASTM A240 UNS S41003. Additionally, it can be certified to European standard EN 10088-2 type 1.4003. It is also included in the specification EN 10028-7 for stainless steels suitable for pressure purposes, which includes minimum specified impact values.
The substantially austenitic microstructure at elevated temperatures also restricts grain growth during welding. This leads to a tough duplex martensitic/ferritic heat affected zone, responsible for good weldability.
