NHF-CrMn

Specification

AWS Specification: N/A
JIS Specification: N/A
Other Specification: N/A

Description

NHF-CrMn is a special low hydrogen basic electrode with chrome and manganese
Formulated for surfacing and repair of manganese and carbon steels
Weld metal deposits austenitic structure for improved resistance to abrasion, and cracking for longer use
Easy to control, with stable arc, and easy slag detachment

Application

Worn out parts of mining equipment, earth moving equipment, railway points, crossings, and other parts made of manganese

Remarks

Use as buffer layer prior to hardsurfacing

Weld join on manganese castings to mild steels and other carbon steels where welding is difficult

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.
