Nihonweld NC-50S description: A counterpart of NC-50 with high hardness due to additional of Mn.
APPLICATIONS:
For repair of cast iron housing blocks, making and all application of NC-50 where higher tensile and harder deposit is required.
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 100-200C in accordance with kind, shape and size of base metal.
