Manganese Steel ASTM A128 GR B-3 Mechanical Property
No Mechanical Property required in ASTM A128 standard.
Manganese Steel ASTM A128 GR B-3 Heat Treatment Requirement
Grade B3 shall be suitably heat treated to achieve toughness and ductility. This heat treatment shall consist of uniformly heating the castings to a temperature applicable for grade of steel produced, at least 1800°F [1000°C], and holding until the temperature is uniform throughout and quenching in an applicable medium, normally water.
For further machining, anneal is recommended at the temperature from 900 to 1100°F [500 to 600°C].
ASTM A128 Grade B-3 WELDABILITY
Manganese steel do not have good welding performance. No preheat required and control the temperature in 300 °C to avoid brittle, welded after quenching.
Manganese Steel ASTM A128 GR B-3 Application
the material is mainly used as wear-resistant steel castings, such as impact curtain, crushing chamber, crushers, blow bars, impact plates, side liners
Manganese steel Machinability:
Bad. Must be operated with high quality ceramic cutting tools
