GTAW
- AUSTENITIC STAINLESS STEELS
307
Description
Solid rod for dissimilar joints and buffer layers
Mixed welding applications including the welding of C-Mn, stainless, hardenable and armour steels to themselves or each other. Suitable also for depositing stress relaxing buffer layers on crack sensitive base metals and hardfacing jobs. Weld metal has a high degree of corrosion resistance and resistant to operating temperatures up to 300°C and non-scaling up to 850°C. Resistance to hot cracking is provided by the high manganese content. The increased silicon results in increased weld pool fluidity to give a smooth deposit appearance.
