Cromgard is a low cost stainless steel, which is able to provide benefits of good weldability and formability, making it capable of fabrication by conventional techniques. It provides the benefits of strength, corrosion and abrasion resistance, durability and low maintenance. 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. |
