Q370R generally offers a higher yield strength compared to Q345R, making it more suitable for vessels requiring higher pressure ratings while maintaining excellent weldability and toughness.
Yes, we provide specific grades designed for low-temperature environments, ideal for cryogenic transport equipment and pharmaceutical sterile storage tanks.
We offer a full suite of processing services including precision CNC cutting, professional bending, welding, and punching to deliver components ready for assembly.
Our plates are packaged with waterproof paper, inner protective steel rings, protective wood blocks, and heavy-duty metal band strapping to prevent corrosion and deformation.
These grades are widely used in the energy and power sectors for boiler drums and heat exchangers, as well as in petrochemical reactors due to their high-temperature strength.
Our minimum order quantity is 1 Ton. To ensure the material meets your project specifications, we provide samples freely upon request.
