Surfacing Rod ECoCr-A
I. Core Performance and Applications
ECoCr-A surfacing welding electrode rod is specially designed for industrial vulnerable and corrosion-prone parts. With excellent high-temperature stability and mechanical strength, it has become a key material for the maintenance and manufacturing of heavy industrial equipment.
1. Application Scenarios
Impact and wear-resistant parts: Key stress-bearing components of crushers, rail contact surfaces, blade edges of bulldozer buckets
High-temperature corrosion-resistant parts: Sealing surfaces of high-temperature and high-pressure valves, working edges of hot shearing tools under 650°C working conditions
Core functions: Meeting the requirements of wear resistance, corrosion resistance, and high-temperature resistance (650°C) simultaneously to extend the service life of equipment
2. Specification Parameters
