Product advantages

High strength, weight reduction, economic

By adding micro-alloying elements such as niobium and vanadium, A572 Gr50 can reduce the structural self-weight by 10-15% at a yield strength of 345 MPa compared to ordinary carbon steel, thereby lowering transportation and construction costs.

Excellent welding and processing performance

The low-carbon equivalent design (Ceq ≤ 0.45) ensures excellent weldability, suitable for various welding processes (SMAW, GMAW, SAW), and is easy to cut, bend and drill.

Outstanding fatigue resistance and impact toughness

Maintains stable impact performance within the temperature range of -20°C to normal temperature, suitable for structural components subjected to dynamic loads, such as crane booms and railway vehicle underframes.

Full-process quality traceability

Each batch of steel plates comes with a factory test certificate (MTC) that complies with EN 10204 3.1 standard, and third-party inspections by SGS, BV, etc. can be arranged.

User Evaluation

The A572 Gr50 steel plate has stable quality, with both yield strength and impact toughness meeting the project requirements. Yuxin's delivery was very timely, and the MTC certificate provided with the goods was complete and clear. The third-party testing was also successfully passed at one go. We have been cooperating on three projects consecutively and it is very reliable.

Purchasing Manager

We mainly use A572 Gr50 for the boom of the excavator. The welding properties and plate shape of this material have very high requirements. The steel plates provided by Yuxin have a smooth surface, and there were no problems with cutting and welding. The after-sales response was also quick, and the overall cooperation was very smooth.

Heavy machinery manufacturing enterprise

For the first time, we purchased A572 Gr50 from Yuxin. The trial order was only 10 tons. They supported small batches and the service was very professional. The communication from inquiry to shipment was efficient, and the packaging and shipping arrangements were all well done. We will increase the purchase volume in the future.
