NIHONWELD NC-50S
AWS Specification: ENi
JIS Specification:

DFC Ni

Other Specification:

DIN ENiG4

I. APPLICATIONS:

For repair of cast iron housing blocks, making and all application of NC-50 where higher tensile and harder deposit is required.

     II. DESCRIPTION: 

     A counterpart of NC-50 with high hardness due to additional of Mn.

     III. NOTES ON USAGE:

  • Clean base metal before welding.

  • If there is a possibility that cracking spreads, make the stopholes at both ends of repairing part.

  • Keep bead length less than 50mm to disperse welding heat.  Adopt back step, stepping stone or symmetry method by turns.

  • Hot peen in every pass.

  • It is not necessary preheating and postheating in general but satisfactory results can be obtained by preheating at 100-200ºC in accordance with kind, shape and size of base metal.

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.
