Specification
AWS Specification: N/A
JIS Specification: N/A
Other Specification: N/A
Description
  • NHF-13H is a lime type electrode in which Mo is added to the base of 13% Cr steel
  • Weld metal features martensitic structure
  • Excellent resistance to heat, corrosion, and abrasion
  • Remarkable crack resistability
  • Rich surfacing welds can be obtained
  • Designed to prevent the dilution from base metal because of shallow welding penetration
  • Provides weld metal of stable hardness of first-layer welding

NOTE:

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. 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.

  • Pre-heat at 200C to avoid cracking
  • Dry the electrodes at 300-350C for 30-60 minutes before use
  • machining as welded condition is impossible
  • Hard surfacing of punches, hot forging dies, and screw conveyors
