GrabPak 309L Electrodes 0.5kg

Features and Applications

Rutile coated low carbon electrode for use in high strength unalloyed and heat treatable steels, ferritic Cr and austenitic CrNi steels, austenitic Mn steels

Similar type austenitic stainless steels, dissimilar metals, buffer layers on mild and low alloyed steels prior to build up or overlaying with any stainless electrodes, joining of corrosion resistant stainless steel with mild or low alloy steels, clad steels

Good crack resistance with hard to weld steels

The weld metal contains a high ferrite %

Requirement of re-drying for minimum 2 hours at temperatures between 120°C-200°C

Unalloyed tempered steels, tool steels, hard manganese steels and hard to weld steels

Typical Base Material Grades
