What are the properties of Q355B low alloy steel?

Q355B steel plate is mainly used for manufacturing bridges, ships, vehicles, boilers, high-pressure vessels, oil and gas pipelines, large steel structures.

Q355B low alloy steel plate performance

1.High strength: generally its yield strength is above 300MPa;
2.High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600 kJ / m to 800 kJ / m. For large welded components, high fracture toughness is also required;
3. Good welding performance and cold forming performance;
4. Low cold brittle transition temperature;
5. Good corrosion resistance.
