Frequently Asked Questions
Q370R generally has higher yield strength than Q345R. It may suit vessels requiring higher pressure ratings, while retaining the weldability and toughness described for these grades.
Specific grades for low-temperature service are available for applications such as cryogenic transport equipment and pharmaceutical sterile storage tanks. Confirm grade suitability against your operating conditions.
Available services include precision CNC cutting, bending, welding, and punching to help prepare components for assembly.
Packaging includes waterproof paper, inner protective steel rings, protective wood blocks, and heavy-duty metal band strapping to help prevent corrosion and deformation.
These grades are used in energy and power applications, including boiler drums and heat exchangers, as well as 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.
