Copper-coated wire for MIG welding 1 1/4 CR- 1/2 Mo creep-resisting steel, conforming to the AWS/ASME specification.
Applications
These consumables are designed for prolonged elevated temperature service up to 550°C. The main areas of application are associated with a steam-generating power plant, eg piping, turbine castings, steam chests, valve bodies and boiler superheaters. Some of the consumables will also find service in refineries where they are used for corrosion resistance to sulphur-bearing crude oil at 250-450°C. Some of the consumables will also find applications in the chemical and petrochemical industries where they are used for resistance to hydrogen attack in the fabrication of hydrocrackers, coal liquefaction plants and NH3 pressure vessels operating at up to 450°C. In the as-welded condition, the consumables also provide a useful source of 300HV hardness weld deposit for build-up or hard surfacing to resist metal-to-metal wear and heavy impact.
