Frequently Asked Questions
Q370R generally has higher yield strength than Q345R. It may suit vessels requiring higher pressure ratings while retaining good weldability and toughness.
Specific grades are available for low-temperature environments, including applications such as cryogenic transport equipment and pharmaceutical sterile storage tanks. Confirm the grade against your design requirements.
Available services include precision CNC cutting, bending, welding, and punching. These processes can prepare components for subsequent assembly.
Packaging uses waterproof paper, inner protective steel rings, protective wood blocks, and heavy-duty metal band strapping to help protect the plates from corrosion and deformation during transit.
P355GH and 15Mo3 are used in energy and power applications such as boiler drums and heat exchangers, as well as in petrochemical reactors where high-temperature strength is required.
The minimum order quantity is 1 Ton. Samples are available free upon request so you can assess the material against your project specifications.
