Application

What diamondspark CM 2 MC metal-cored wire is used for

diamondspark CM 2 MC is a seamless, creep resistant metal-cored wire alloyed with 2.25 percent chromium and 1 percent molybdenum.

Base materials are 10CrMo9-10, 16CrMo9-3, 11CrMo9-10, 26CrMo7, G17CrMo9-10, G19CrMo9-10 and ASTM A 182. The seamless sheath protects the core against moisture even after long storage, and the deposit resists creep at elevated temperature.

  • Classification EN ISO: 17634-A T CrMo2 M M21 1 H5
  • AWS classification: A5.28 / SFA-5.28 E90C-B3H4
  • Shielding gas: M21
  • Diameters: 1.2 / 1.6 mm
  • Approvals: TÜV (07159), CE

Do not interrupt welding and do not let the joint drop below the interpass temperature before the fill is finished. 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.
