NHF-160MC (rutile)
AWS Specification: NONE
JIS Specification:

NONE

Other Specification:

I. APPLICATIONS:

Joining and Surfacing of 14% Mn steels and most all hard-to-weld steels when high impact resistance and cavitation resistance is required. Buffer layer before depositing.

II. DESCRIPTION:

NHF-160MC is a rutile coated hardsurfacing welding electrode with 140% recovery. Impact resistance is excellent with medium abrasion resistance. Machinability is only possible if not work hardened.

TEST RESULT

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.
