diamondspark CM 5 BC is a seamless, creep resistant flux-cored wire of the basic type, alloyed with about 5 % Cr and 0.5 % Mo.
Parent materials are X12CrMo5, GX12CrMo5 and ASTM A 213. The seamless make limits moisture pickup by the core and 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 CrMo5 B M21 3 H5
- AWS classification: A5.29 / SFA-5.29 E80T5-B6M-H4
- Shielding gas: M21
- Diameters: 1.2 mm
- Approvals: CE
Plan the preheating and the post weld heat treatment to the WPS for the grade in hand, CrMo steels harden in the heat affected zone. Take care of degassing and a clean groove, basic slag will not forgive oily edges. Keep the wire in a dry store and use an opened pack promptly, a basic core is sensitive to moisture.
