Material Notes:

RoyAlloy™ is a 400 series martensitic stainless steel supplied prehardened. RoyAlloy™ is characterized by excellent machinability, good corrosion resistance, uniform and consistent hardness in all dimensions, good resistance to indentation (compressive strength), excellent ductility, excellent flatness, dimensionally stable, smooth as rolled surfaces, excellent weldability, and good thermal conductivity. RoyAlloy™ is an improved stainless grade designed specifically for plastic molding applications. Chemical composition and thermal treatments provide physical properties and microstructures designed to provide reduced mold maintenance costs, worry free weld repair, dimensional stability, and lower mold production costs due to less cutting tool wear and increased cutting speeds. Applications: plastic and rubber molds, plastic mold bases, plastic mold inserts, constructional parts, plastic extrusionInformation provided by EDRO
