Q: Is Q345 suitable for outdoor use?
A: Yes, it is. Rust removal, painting, and anti-corrosion treatment are required. It can be used long-term in outdoor engineering structures.
Q: Does Q345 require special welding processes?
A: Conventional electric welding and gas shielded welding are sufficient. Thick plates require preheating. Ordinary welders can operate normally.
Q: How is the high-temperature resistance of Q345?
A: It is stable under normal and medium temperature conditions. It is not suitable for high-temperature boiler applications. High-temperature applications require specialized heat-resistant steel.
Q: Can Q345 be bent, punched, and cut?
A: Absolutely. Bending, plasma cutting, laser cutting, punching, and stamping are all suitable.
Q: Is Q345 carbon steel or alloy steel?
A: It is a low-alloy high-strength carbon steel, containing a small amount of alloying elements to improve strength and toughness.
