NHF-716

Specification

AWS Specification: N/A
JIS Specification: N/A
Other Specification: DIN: E10-60C

Description

NHF-716 features high deposition rate, little spatter, minimum diulation with the base metal, and smooth seams
Weld metal deposit is corrosion and wear resistant
Chromium carbides are regularly distributed in the deposit

Application

Surfacing of parts subject to severe abrasion but moderate impact
Sand slides
Converyor screws
Mixing paddles
Bucket edges
Crusher jaws
Digger teeth

Remarks

Preheating is not necessary

Grind weld area

If necessary, preheat at 200-400�C

Manganese steel must not be preheated and should be welded as cold as possible

Apply 2-3 layers to develop full properties of weld deposits

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.
