GB713 14Cr1MoR for heat exchanger
Products Description
14Cr1MoR is a type of Cr-Mo hydrogen-resistant alloy structural steel, which implements the GB713-2008 standard.
In its name, "14" represents a carbon content of approximately 0.14%, "Cr" and "Mo" refer to the elements chromium and molybdenum respectively, and "R" indicates a steel plate for pressure vessels.
The delivery state is pre-quenched and tempered, with a hardness range of 270-340HB. This steel grade controls the content of impurities such as Sn and Sb through processes like vacuum degassing and temperature-controlled rolling. Its thickness can cover 8-120mm, and the maximum width reaches 3900mm.

Key Characteristics of 14Cr1MoR
High-temperature resistance: Chromium and molybdenum elements enhance high-temperature strength and creep resistance, enabling long-term stable operation in high-temperature environments.
Corrosion resistance: It has good resistance to hydrogen corrosion and high-temperature sulfide corrosion, making it suitable for scenarios in contact with hydrogen or hydrogen-mixed media.
Weldability: Under the condition of strictly controlling the welding process, it is not easy to produce cracks and pores, and the welded joint has high strength.
Production Process
The production process of 14Cr1MoR steel plate includes steps such as electric furnace steelmaking, LF/VD refining, rolling, and heat treatment. Among them, the heat treatment process has an important impact on the performance of the steel plate, including steps like quenching and tempering, so as to obtain the required mechanical properties and processing performance.
Cutting and Processing
14Cr1MoR steel plate has good processability and can undergo processing operations such as cutting, bending, and rolling. Common cutting methods include laser cutting, plasma cutting, flame cutting, and water jet cutting, etc. The specific selection depends on the thickness of the steel plate and the cutting requirements.
Main Application Fields of 14Cr1MoR
Due to its performance advantages, 14Cr1MoR steel plates are widely used in the following fields:
Petrochemical industry: Equipment such as reactors, distillation towers, heat exchangers, and storage tanks, which need to withstand high-temperature, high-pressure, and strong corrosive environments.
Power industry: Key components such as boilers, steam turbines, and generators, which are adapted to high-temperature and high-pressure working conditions.
Nuclear power field: Large pressure vessels and structural parts, which require long-term stability and safety of materials.
Shipbuilding and marine engineering: Hull structures and marine engineering equipment, which can adapt to complex corrosive environments at sea.
