Metrode Chromet-5 description: For elevated temperature service up to 600ºC, with corrosion resistance in superheated steam, hot hydrogen gas and high sulphur crude oils. Used primarily for boiler superheaters, heat exchangers, piping and pressure vessels in oil refineries. This weld metal has also been used successfully for subsequent nitriding, for example in the repair of 3Cr-1Mo-V and 2Cr-Mo-1A1 (BS En40C, En41) steels used for moulds for injection-moulding of plastics.
