ENiCrMo-4  - ISOARC 276   

Descriptions
Isoarc 276 Is an MMA electrode for the manufacture and repair of hot forming tools and for oxidation and corrosion resistant overlays.It is used for the manufacture and repair of drop forging dies, hot forming dies, pump impellers, retorts and valves. Not only can it be used for overlays , but it can be used for joining special alloys such as Hastelloy C276 to itself or to stainless steel.High temperature stability is limited by intermetallic phase formation in addition to fabrication welds in alloy 267, these consumables have good tolerance to dilution by most ferrous and high nickel alloys, and are suitable for surfacing and dissimiliar welds which exploit the corrosion resistance.

Characteristics
Isoarc 276 is a heavily coated electrode with approx. 170% metal recovery. The electrode has excellent welding characteristics and de-slagging properties.

Applications
Applications include pumps, valves, pipework and vessels for use in aggressive environments in Chemical processing plants, Cement processing plants; also in equipment for flue gas desulphurisation and critical equipment in offshore oil and gas production.

Redrying
If moist re-dry for 2 hours at 250degC.
