DIN 8555 MF 7-250-KNP
DESCRIPTION
- Hardcored AP is a self-shielded flux-cored wire designed to produces am austenitic high manganese and high chromium weld deposit.
- The fully austenitic weld deposit is corrosion resistant, non-magnetic and has an excellent work-hardening properties.
- It can be use for buffer, build up or joining on new or used components subject to high impact loading (Hàn đắp)
TYPICAL APPLICATIONS: Hammers, welding on Hadfield manganese steel, railroad frogs, jaws and crusher
