Selecting Welding Materials for Mn13 High Manganese Wear-Resistant Plates
Welding Rods
For welding Mn13 high manganese wear-resistant plates, a low carbon steel welding core is used. Alloying elements are added to the coating to give the deposited metal the chemical composition and mechanical properties of the Mn13 plate.
There are two types of welding rods commonly used:
- High Manganese Steel Type Rods:
- D256 (EDMn-A-16) and EDMn-B-16: These rods are primarily used for surfacing parts exposed to severe impact and abrasive wear, such as crusher jaws.
- Cr-Mn Type Rods:
- D276 (EDCrMo-B-16) and D277 (EDCrMo-B-15): These rods have a surfacing metal in a medium-stable state of high manganese austenite. When subjected to strong impacts, they transform into martensite. They are mainly used for cavitation-resistant surfacing or high manganese steel surfacing, such as turbine blades and excavator bucket teeth.
Welding Wires
Welding wires for Mn13 high manganese wear-resistant plates include several types:
- High Manganese Steel Wires:
- Mn-Ni, Mn-Cr, Mn-Mo, and Mo-Ni-Cr Series: These are high manganese steel welding wires.
- Alloy Steel Wires:
- Cr-Ni and Cr-Ni-Mn Series: These wires offer high corrosion resistance and can harden rapidly under impact loads. They also allow for high dilution when welding high manganese steel with carbon steel or low alloy steel. These wires are suitable as filler materials when welding high manganese steel and carbon steel.
The Cr-Ni series welding wires provide both high corrosion resistance and rapid hardening capabilities, making them ideal for challenging welding conditions. Report this page
