RATNA 7016 (AWS A5.1 E7016)

A Hydrogen Controlled Basic Coated Electrode For Welding High and Medium Tensile Steels

Classification:

AWS/SFA-5.1: E 7016 , BS 639 EB5144B24(H)
IS-814: EB 5426H3X , DIN 1913 5144B1026

Characteristics:

A hydrogen controlled basic coated electrode for welding medium and high tensile structures, grey cast iron components, low and medium carbon steels. The deposits are of radiographic quality coupled with excellent mechanical properties.

Application:

  • Suitable for overlaying buffer layer before hardfacing.
  • Joining mild steel to carbon steel.
  • Repairing cast iron components (non-machinable welds permitted).
  • Joining steel girders to rail.
  • Earthmoving machinery.
  • Boilers, offshore drilling rigs and platforms.
  • Pressure vessels and storage tanks.
  • Blast furnace shells.

Re-Dry Condition:

Re-dry the electrode at 250°C for one hour for best results.
