What diamondspark DCMS MC metal-cored wire is used for

diamondspark DCMS MC is a seamless, creep resistant metal-cored wire alloyed with 1 percent chromium and 0.5 percent molybdenum. It is used in boiler making, on pressure vessels and petrochemical installations.

Base materials include 1.7335, 13CrMo4-5, 1.7262, 15CrMo5, 1.7728, 16CrMoV4 and 1.7218. The seamless construction limits moisture pick-up in the core, and the deposit resists creep at elevated temperature.

  • Classification EN ISO: 17634-A T CrMo1 M M21 1 H5
  • AWS classification: A5.28 / SFA-5.28 E80C-B2H4
  • Shielding gas: M21
  • Diameters: 1.2 / 1.6 mm
  • Approvals: TÜV (07158), CE

Watch the hydrogen level, dry consumables and a preheated groove are your basic protection against cold cracking. Keep the gas cover complete, without a full slag layer the pool is more sensitive to draughts. Check the feed roll pressure, a metal-cored wire is easier to crush than a solid one.
