In addition to grade-specific features, all Cromgard® grades offer the following additional benefits:
Cromgard® is a “cost stable” stainless steel, which means it is not subject to erratic price fluctuations because it does not depend upon expensive alloying elements like nickel and molybdenum. It has therefore maintained a consistently lower cost advantage compared to other corrosion-resisting materials. Cromgard® also helps to reduce costs by eliminating the need for protective treatments and material corrosion allowances.
Cromgard® provides good weldability and formability, making it capable of fabrication by conventional techniques. The substantially austenitic microstructure at elevated temperatures also restricts grain growth during welding, which leads to a tough duplex martensitic/ferritic heat affected zone.
In service, Cromgard® generates savings in maintenance, improved productivity and longer service life. In a wide variety of applications, it has been extremely successful in displacing coated carbon steel, Corten and aluminum. In every case, Cromgard® demonstrates a realistic performance or economical advantage, often both.
Cromgard® has several notable characteristics at elevated temperatures: reasonable mechanical properties; good scaling and oxidation resistance, including resistance to sulphur-bearing atmospheres; negligible embrittlement after extended exposure to temperatures between 842°F and 1022°F; and resistance to many hot gases and fumes generated in industrial processes.
The Cromgard® Family of Stainless Steels was created to impact the total life cycle cost of equipment. While these metals are certainly cost effective on the front end, their benefit is even more impressive on the back end helping to reduce future cost such as maintenance, raw materials, labor and downtime (or removal of the equipment from service).
