Detalles
EXCALIBUR® 320LR-16 provides good corrosion resistance in acidic environments and requires low heat input welding procedures be used to prevent solidification cracking.
Características
- Good corrosion resistance in acidic environments
- Low heat input welding procedures should be used to prevent solidification cracking
- Designed to produce a high purity weld deposit which reduces weld metal fissuring - Often encountered in fully austenitic stainless weld metals
