Duplex stainless steel fasteners are selected for applications that require a combination of strength and corrosion resistance.Common duplex grades such as 2205 (UNS S31803 / S32205) are used in marine, chemical processing, water treatment and industrial equipment, subject to the design environment. The exact grade, mechanical properties, manufacturing standard and corrosion requirements must be specified for each order. Supply should be confirmed against Canco’s actual sourcing or manufacturing capability. Bulk supply, private-label packaging and made-to-drawing variants may be offered subject to Canco’s actual capability and order agreement. Material test certificates and other documentation should be confirmed before they are stated as available.
