diamondspark DMO MC is a seamless metal-cored wire for creep-resistant CrMo steels. It works in power plant, on superheaters, headers and pressure pipework in chromium molybdenum steels.
Base materials include S235JR, S355JR, S235JO, S355JO, S450JO, S235J2 and S355J2. The seamless sheath protects the core against moisture even after long storage, and the wire is used in boiler making, on pressure vessels and petrochemical installations.

Watch the hydrogen level, dry consumables and a preheated groove are your basic protection against cold cracking. Check the feed roll pressure, a metal-cored wire is easier to crush than a solid one. Set the parameters for spray arc, in the short arc range a metal-cored wire loses its deposition advantage. Thinner diameters suit root runs and thin sheet, thicker ones suit filling.
