Application

What diamondspark CM 2 BC flux-cored wire is used for

diamondspark CM 2 BC is a seamless, creep resistant flux-cored wire of the basic type, alloyed with about 2.25 % Cr and 1 % Mo.

Typical parent materials are 16CrMo9-3, 11CrMo9-10, 26CrMo7, G17CrMo9-10, G19CrMo9-10 and ASTM A 182. The seamless make keeps the hydrogen level in the weld low, and the deposit stands up to creep on boilers, steam lines, refinery plant and parts working at elevated temperature.

  • Classification EN ISO: 17634-A T CrMo2 B M21 4 H5
  • AWS classification: A5.29 / SFA-5.29 E90T5-B3M-H4
  • Shielding gas: M21
  • Diameters: 1.2 mm
  • Approvals: CE

Do not break off welding and do not let the joint cool below the interpass temperature before the fill is finished. Hold a short arc, a long one breaks the shielding and raises the hydrogen content in the weld. Take care of degassing and a clean groove, basic slag will not forgive oily edges.
