AWS Specification: none
JIS Specification:

DFCr-A-700-B

Other Specification:

I. DESCRIPTION:

Good for heavy abrasion, NHF-32CRS can reach more than 700 Hv. The weld metal consists of 30% Cr. Machining is not possible due to the high amount of Chrome. Preheating should be used roughly 300 deg C. To prevent disbanding and cracking, an underlayer should be applied as well.

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.
