RF40(Grimm Edelstahl) - Chromium stainless steel. Good workability when hot. Used for applications requiring hardness and corrosion and wear resistance. (Corrosion resistance reduced when not heat treated, heat treated and polished resists rust, diluted nitric acid and mild organic acids). Bad weldability. Similar to AISI 420 steel.
