Features and uses:
- SLH-58 is a 490N/mm grade 2 iron powder ultra-low hydrogen high-tension steel electrode with excellent impact value at low temperatures of -45°C.
- Suitable for large steel frame structures, barrel tanks, power plants and petrochemical industries.
Notes:
- Before welding, the electrode must be dried at 300~350℃ for 60 minutes. When using, take out a small amount and put it into a drying cylinder with a temperature of 100~150℃. The maximum amount of electrodes taken out is the amount of the day.
- To prevent arcing and air holes, please use the backward and forward method.
