Mn13 고망간 내마모판용 용접 재료 선택

Welding Rods

For welding Mn13 high manganese wear-resistant plates, 저탄소강 용접 코어가 사용됩니다.. 도금된 금속에 Mn13 판의 화학적 조성과 기계적 특성을 부여하기 위해 합금 원소가 코팅에 첨가됩니다..

일반적으로 사용되는 두 가지 유형의 용접 막대가 있습니다:

1. 높은 망간 강철 유형로드:
   • 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.
2. 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:

1. High Manganese Steel Wires:
   • Mn-Ni, Mn-Cr, Mn-Mo, and Mo-Ni-Cr Series: These are high manganese steel welding wires.
2. 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.
