Stainless Steel Materials

Discover the complete range of stainless steel grades used in spiral wound gasket manufacturing. Compare corrosion resistance, mechanical properties, operating temperatures, international standards and engineering characteristics before selecting the right material for your sealing application.

Why Stainless Steel?

Stainless steel is the most widely used metallic winding material for spiral wound gaskets because it provides an excellent combination of corrosion resistance, mechanical strength, oxidation resistance and long service life. Different grades are selected depending on process media, operating temperature, pressure and environmental conditions.

Ferrobend provides engineering information for every stainless steel grade commonly used in spiral wound gasket manufacturing. Each grade includes complete chemical composition, mechanical properties, physical properties, operating temperature limits, heat treatment information, international standards and industrial applications.
