DETAILS
Features/Characteristics
Senor SME 312-16 is a rutile based medium coated all position electrode giving 30Cr/10Ni deposit which has excellent oxidation resistance. The weld metal has a two phase structure with substantial amount of ferrite in the austenitic matrix. The deposited weld metal is highly resistant to weld metal cracks and fissures. Gives a quiet and stable arc, low spatter, smooth weld bead and easily detachable slag.
SME 312-16 Welding Rod Uses/Applications
- Welding difficult to weld steels e.g. high carbon hardenable tool, die and spring steels, 13% Mn steels, free cutting Steels, high temperature steels.
- Joining/welding of dissimilar steels, cast steels nickel steels, chrome steels
- Marine, re-conditioning and refurbishment industries
- Welding wrought and cast alloys of similar composition
Welding Positions
