We have established long-term partnerships with hundreds of factories to ensure that these products are manufactured using high-quality materials and are in sync with various international standards.
What are the excellent performance parameters of Q245R?
q245r is a boiler and pressure vessel steel with a yield point of 245MPa. "Q" represents the yield point of steel, the following number represents the yield point value in MPa, and "R" represents the container. It has special composition and performance and is mainly used as a pressure vessel. Depending on the use, temperature, and corrosion resistance, the material of the container plate that should be selected is also different.

Reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, and liquefied petroleum made with Q245R in the petroleum and petrochemical industry, chemical equipment manufacturing companies, power station construction, boiler and pressure vessel manufacturing and other companies Cylinders and turbine volutes. Due to the harsh conditions of use in petrochemical industry, coal conversion, nuclear power, steam turbine cylinders, thermal power, etc., large equipment with complex corrosive media such as: water washing towers, second conversion furnaces, coke towers, desulfurization tanks, conversion Q245R (Hic) steel plates are widely used in gas waste heat boilers, methanation furnaces, reactors, regenerators, hydrogenation reactors, methanation heaters, reformed gas steam generators and other equipment and component construction projects.
