Ultimate-18MET:

ULTIMATE-18MET is an outstanding electrode designed for several stringent applications demanding the best in terms of total weld quality. This unique electrode is capable of yielding welds which are of radiographic quality, combined with exceptionally high impact strength and crack resistance. Thus it is suitable for a very wide range of grain-refined steels having tensile strength in the range 500 to 620 N/mm² as well as difficult steels containing higher carbon or higher levels of sulphur and other impurities.

• features which every welder and welding engineer ULTIMATE-18MET represents a unique combination of look for on shop floor and at erection site
• Ease of operation in all positions.
• Slag detachability with little effort.
• Smooth and stable arc which is easy to strike & restrike, combined with low spatter and with due control on molten pool.
• Finely rippled bead with regular profile.
• Welds of consistent X-ray quality.
• Weld metal which possesses excellent mechanical properties and displays resistance to cracking caused by heavy stresses and /or hydrogen. In particular, it displays remarkable impact resistance at subzero temperatures down to minus 50°C.
• A higher level of metal recovery at 110-115%.
• Resistance to moisture pick-up.
• Weld metal is characterised by resistance to ageing.
• Suitability for prolonged S.R., or Normalising followed by S.R., without embrittlement,
• very low hydrogen content.
• radiographic quality
