307
Description
Solid wire 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, e.g. crane wheel surfacing where high degree of pressure and dynamical loads exists. 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.
