Product Description

Classification :

  • IS : 1395 - 82 : E 55B - GI 29 Fe
  • AWS / A 5.5 : E 8018-G

Description :

A low hydrogen iron powder electrode suitable for welding heavy sections of fine grained high strength steels with particular reference to low temperature service down to minus 60o C. Metal recovery is over 110%.

Applications :

  • Steels containing Nickel up to 1.5%
  • Low alloy steels such as Si - Mn steels.
  • Q & T steels for pressure vessels, tanks and pen stocks, where high strength and subzero temperature toughness properties are of importance.
