Test5678

Hard facing electrode for moderate wear and heavy impact.

CHARACTERISTICS :

Basic coated, hydrogen controlled, iron powder electrode depositing weld metal containing about 1.4% Mn and 0.70% Ni. The electrode is specially recommended for welding thick sections of fine grained, high tensile low temperature steels. The weld metal gives excellent impact strength down to minus 60°C. Deposited welds ar of radiographic quality.


TYPICAL APPLICATION :

Welding of fine grained, Q&T steels for pressure vessels, tanks, penstocks, where high strength & sub subzero temperature toughness properties are of of importance.For fabrication of LPG bullets, medium tensile like BH 39, BH 47, BH 1027, Aldur 45, Aldur 60 etc.
