A514 Grade Q is a quenched and tempered alloy steel plate that exhibits high yield strength, strong weldability and good toughness at low atmospheric temperatures.
A514 Grade Q is a high-strength alloy steel plate with corrosion resistance and wear resistance. It is widely used in construction engineering, ship manufacturing, bridge construction and other applications. A514 Gr.Q steel plate also has excellent heat resistance and fatigue resistance, can operate at high temperatures, and is used to manufacture equipment and machines that operate under extreme working conditions.
ASTM A514 Gr.Q is designed for a variety of structural uses, as well as industrial machinery and equipment, and has some features:
- Impact resistance
- High strength
- Fair grinding and machining potential
- Corrosion resistance
- Durable
- Long-term economy
- Abrasion resistance
