Description
Supratherme-Ni(Spl)H4R is a basic coated, low hydrogen, moisture resistant, iron powder type electrode yielding a weld metal containing 1.5Mn and 0.7Ni. Excellent quality welds for welding heavy sections of fine-grained high strength steels with particular reference to low temperature service down to minus 50°C. Typical applications include welding of fine grained Q&T steels for pressure vessels, tanks, penstocks, where high strength and sub-zero temperature toughness properties are of importance.
