APPLICATIONS
Used for cast iron application same as VC-100 but where higher tensile and harder deposit is welded.
CHARACTERISTIC
A counterpart of VC-100 with higher strength hardness fue to addition of Fe
NOTES ON USAGE
1.) Clean base metal before welding.
2.) If there is a possibility that cracking spreads, make the stopholes at both ends of repairing part.
3.) Keep bead length less than 50mm to disperse welding heat. Adopt back step, stepping stone or symmetry method by turns.
4.) Hot peen in every pass.
5.) 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.
