AWS Specification: NONE
JIS Specification:

DF2A-450-R

Other Specification:

DIN 8555: E1-350

I. APPLICATIONS:

Surfacing parts for longer use, of shear blades, hot-punching dies, wobbler ends, large cog-wheels, plough shares, cams, rollers, brake shoe, caterpillar treads, rail ends and crossing, and other steel castings.

 

II. DESCRIPTION:

A rutile coated electrode for surfacing carbon steels subjected to metal to metal wear with resistance to impact and moderate abrasion. Easier to strike with minimal spatter, stable arc and good running properties. Welding in all position.

 

III. NOTES ON USAGE:

  • Preheat at 150ºC and over in general.

  • In the case of multi-layer build-up welding or hardenable steel welding, underlay with low hydrogen type electrode (N-7016 0r N-8016).

  • Dry the electrodes at 300~350ºC for 30~60 minutes before use.

Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
