       ASTM 4119 is equivalent to 12CrMo. This alloy steel is mainly used to produce small-diameter seamless steel pipes and hot-rolled materials. In boilers and steam turbines, ASTM 4119 steel can be used to manufacture main steam pipes, which can withstand steam parameters up to 510°C, and superheated pipes with tube wall temperatures up to 540°C. In addition, after quenching and tempering treatment, ASTM 4119 steel can also be used to manufacture various elastic components that work in high-temperature environments.

ASTM 4119 steel has outstanding properties and has high strength and high-temperature strength. It can maintain good mechanical properties in high-temperature environments, ensuring reliability and stability of work. Whether at high temperatures or room temperature, ASTM 4119 steel can meet various project requirements

Common applications of 12CrMoV alloy structural steel include:

1)Common applications: It is used as the main pipe with steam parameters up to 540°C, steering vane ring, steam turbine diaphragm, diaphragm outer ring, and various superheater pipes, pipes, and corresponding forgings with pipe wall temperature <570°C. It is widely used in aerospace, aviation, energy, chemical, machinery manufacturing, and other fields.

2)Storage Tanks: 12CrMoV alloy structural steel is sometimes employed in the construction of storage tanks for storing liquids or gases. Its weldability and strength make it suitable for this application.

3)General Fabrication: 12CrMoV alloy structural steel is widely utilized in general fabrication processes where low-carbon alloy steel with good mechanical properties is required. It can be formed, welded, and machined to create various structures and components.

Production Process


 Production Process

Choose appropriate raw materials, usually alloy materials composed of iron, carbon, chromium, molybdenum, manganese, and other elements. Raw material preparation-smelting-casting-heat treatment-hot rolling-cutting and trimming-inspection and quality control

The raw materials are put into a high-temperature furnace for smelting to completely melt them. Pour the molten alloy liquid into the casting mold and wait for it to cool and solidify to form a cast slab. Heat treatment is performed on the cast blank, usually including annealing, normalizing, quenching, and other processes to improve the mechanical properties and organizational structure of the material. The heat-treated billet is fed into the hot rolling mill, and after multiple passes of rolling and stretching, the thickness of the plate is gradually reduced to form the required alloy plate. The hot-rolled alloy plate is cut to the required size and trimmed to obtain a smooth surface and edges.

Inspect the produced alloy plates, including appearance quality, dimensional accuracy, mechanical properties, etc., to ensure that the products meet the requirements of ASTM 4119 standards.
