HH-808 hardfacing FCW welding wire for Crusher
Charateristics
HH-808 is a high-performance flux cored welding wire, it produces an overlay resistant to abrasion and impact. The weld deposit cannot be machined. The weld material exhibits cracks。
Microstructure: High-chrome-high-carbon complex carbide alloy: C – Cr – Mo – V – Nb – Ni – Fe.
Machinability: Grinding only
Cutting: Not suited for flame-cutting
Cutting: Multi layers.
Application
Perfectly suited for parts subjected to combined impact and abrasive stresses, e.g. cone crushers, pick hammers, dredger teeth, crusher roll and guide rails. The application temperatures should not exceed 450℃.
