BÖHLER EMS 2 CrMo is a submerged arc (SAW) wire for welding creep-resistant CrMo steels. It works in power plant, on superheaters, headers and pressure pipework in chromium molybdenum steels.
The wire joins grades such as S275N, S460N, S275M, S460M, P235GH, P355GH and P355N, along with related materials. It handles pipeline welding including fill passes, and it is used on boilers and pressure vessels under statutory inspection.
- Classification EN ISO: S S CrMo1 FB
- AWS classification: F8P2-EB2-B2
- Shielding: flux matched to the wire, no shielding gas
- Diameters: 1.0 / 2.0 / 2.5 / 3.0 / 4.0 mm
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. Watch the wire stick-out and the position of the head against the weld centre line, under a flux you cannot see the pool and a mistake shows only after the slag is chipped off.
