Q355 is a low-alloy high-strength steel known for its significant strength, allowing it to bear substantial loads. Additionally, low-alloy high-strength steel boasts good plasticity and impact resistance, preventing brittle fracture even at lower temperatures.
Q: The initial letter of the pinyin for the Chinese character representing the yield strength of steel.
355: Represents the yield strength value, unit MPa
B: Represents a quality grade of B-level
Q355B square tubes offer excellent weldability and corrosion resistance. Thus, they are suitable for containers used in applications like oil transportation or chemical component protection. Consequently, these tubes can be used in the manufacturing and production of oil storage tanks, high-pressure vessels, boilers, ships, power stations, and various other high-load structural components. These tubes are durable in such environments, with a long service life and resistance to damage from environmental and weather factors.
Q355B square tubes are often used in container manufacturing due to their corrosion resistance. For instance, Q355 is widely employed in the production of shipping containers, waste storage containers, weatherproof containers, marine containers, workshop containers, and toolboxes.
