MTC MT-312 1.4337 Stick Electrodes
Rutile-coated MTC MT-312 1.4337 stick electrode for welding dissimilar steels and for hardfacing. Weld metal consists of ferritic-austenitic chrome-nickel steel. Scale-resistant up to +1000°C.
Standard Designation
| EN ISO 3581-A | E 29 9 R 12 |
| Material Number | 1.4337 |
| AWS/ASME SFA-5.4 | ER 312 - 16 |
Important base materials for MTC MT-312 stick electrodes
Corrosion-resistant similar steel and cast steel, e.g., 1.4762 (X10 CrAl 24), 1.4085 (G-X 70 Cr 29); hard-to-weld steel, e.g., high-strength structural steel, manganese hard steel, and joints with high-alloy steel; repairs and wear-resistant hardfacing.
Mechanical properties of the weld metal (typical values)
Heat treatment Test temperature [°C] untreated +20°C (typical values) 0.2% yield strength Rp0.2 MPa 450 Tensile strength Rm MPa 650 Elongation at break A5 [%] 1
Special notes
The favorable coefficient of thermal expansion due to the high delta-ferrite content in the weld metal reduces internal stresses in black-and-white joints and increases safety against hot cracking.
