Q370R Steel Description

Q370R boiler and pressure vessel steel comply with the GB/T713 standard, "Q" means yield strength, "370" means yield value (MPa), and R means container steel. Q370R pressure vessel steel has very high strength, good toughness, wear resistance, impact resistance, fatigue resistance and easy welding and processing properties. It is generally used in the manufacture of boilers and pressure vessel manufacturing, such as petroleum equipment, gas cylinders, Liquefied gas tanks, chemical equipment, pressure vessels, gas tanks, heat exchangers, reactors, spherical tanks and other large containers.

GB/T713 Q370R boiler and pressure vessel plates are delivered in hot rolling, controlled rolling, normalizing and other states. They are all medium and high temperature pressure vessel steel plates with grades Q345R, 15CrMoR, 14Cr1MoR, 12Cr2Mo1R, Q420R, 121Cr1MoVR and other grades, all produced in accordance with GB/T713 standards Carbon steel container plate. BBN Steel can provide Q370R boiler plate steel of different sizes, and can provide cutting and deep processing services according to customer needs.
