For fine-grained high-strength steels
Description
Solid wire for welding high-strength steels (up to 700 MPa) used in highly stressed parts of welded structures. The high-strength weld metal is alloyed with NiMnCrMo. Designed for use at temperatures between -20°C and 350°C.

Processing Instructions
Preparation:
- Remove contaminants, cracks, and worn metal from the welding area. Bevel the joints with V-, U-, or X-profiles according to the thickness.
Preheating:
- Preheating depends on the carbon equivalent of the steel as well as the size, thickness, and geometry of the workpiece. Castolin Eutectic recommends:
- CE < 0.2: Preheating not required.
- CE 0.2 - 0.4: Preheating 100-200°C
- CE 0.4 - 0.8: Preheating 200-350°C.
- Note that 12-14% Mn steels should never be preheated and that the workpiece temperature during welding should be kept below 250°C.
Welding:
- Current Type: = (+) [Electrode positive]
- Possible Welding Modes: Short-circuit transfer, axial spray arc welding, pulsed arc welding. To limit heat input, prefer welding in the air-pulsed arc mode. The interpass temperature should not exceed the preheating temperature.
Welding Parameters:
Wire Ø (mm) | Voltage (V) | Current (A) | Wire Feed (m/min) | Gas (l/min)
0.8 | 15-36 | 40-210 | 3-18 | 10
1.0 | 14-37 | 50-300 | 2-15 | 12
1.2 | 14-37 | 60-350 | 1.5-12.5 | 14
