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 Covered Electrodes MTC MT-312
Corrosion-resistant similar steel and cast steel, e.g., 1.4762 (X10 CrAl 24), 1.4085 (G-X 70 Cr 29); difficult-to-weld steel, e.g., high-strength structural steel, manganese hard steel and connections with high-alloy steel; repairs and wear-resistant overlays.
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 residual stresses in dissimilar joints and increases resistance to hot cracking.
