| Product name：KH-50 |
| Classification：- |
  |
- Weld metal is martensite structure with13%Cr.
- Due to the high hardness of the weld metal, preheat and stress relieving is required to prevent cracks.
- It provides excellent corrosion resistance; acid resistance and impact wear resistance at high temperature.
- It is suitable for repairing conveyers, crane wheels, drive tumblers and chemical conveying screws.
