Product Introduction

12CrMoV alloy structural steel is a pearlitic heat-resistant steel, which has high structural stability and thermal strength when used at high temperature for a long time, and is usually used under high temperature normalizing and high temperature tempering.Its chemical composition and mechanical properties are regulated by the Chinese national standard GB/T 3077-1999.  

 

12CrMoV alloy structural steel is equivalent to A335-P11、A369-FP12 ,A199-T11、A213-T11 in the United States, 1.7335 in Germany, and STPA23/ STBA23 in Japan standard. 12CrMoV alloy structural steel carbon content generally does not exceed 0.15%.

 

12CrMoV alloy structural steel has the following general characteristics:

 

 

1)Low carbon Content: 12CrMoV alloy structural steel belongs to the category of alloy structural steel, cold extruded, carburized and hardened steel. The carbon content in 12CrMoV alloy is generally less than 0.15%, making it a low carbon alloy structural steel suitable for forming processes.

 

2)Excellent Plasticity: 12CrMoV alloy structural steel exhibits good plasticity, allowing it to be formed into various shapes and structures without fracturing.

 

3)Excellent properties: 12CrMoV alloy structural steel has high strength, heat resistance, wear resistance, corrosion resistance and fatigue resistance, toughness, sharpness retention, and this structural steel has high plasticity during cold deformation and can be cut.

 

4)Wide application: 12CrMoV alloy structural steel is widely used in general structural and engineering purposes, including construction, engineering, transportation equipment, aviation, aerospace, energy, chemical industry, machinery manufacturing and other industries that require strength and durabili

Application:

12CrMoV alloy structural steel has a wide range of applications in various industries due to its excellent properties and affordability. Some 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.

 

Classification By Size

The length is generally 2440mm, 2000mm, 3050mm, 4000mm, 3000mm, and the thickness is distinguished by cold rolling and hot rolling. Cold rolling mainly has thickness 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm. The main thickness of hot rolling is 3.0mm, 4.0mm, 6.0mm, 8.0mm, 10.0mm, and the width is generally 1000mm, 1219mm, 1500mm.Please contact customer service for general specifications.


Hot-rolled products have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as steel, construction, machinery, boilers, and pressure vessels. Application range: (1) After annealing, it is processed into ordinary cold rolling; (2) The galvanizing unit with pre-annealing treatment device processes galvanizing; (3) Panels that basically do not need to be processed.


Hot-rolled coils (in the form of flat plates or coils) generally have a thickness of 2.0-13.5mm, of which the price of 2.0-3.0mm hot coils gradually decreases from thin to thick; most steel mills have a basic price of 3.1mm-13.5mm Equivalent, the price of 3.1-4.0mm and 9.5mm-13.5mm hot plate coils in some manufacturers and markets may be higher than the price of 4.0mm-9.5mm plates. Hot plate coils represent products with a thickness of 5.5mm. Under normal circumstances, the price of flat plates is slightly higher than the price of coils.
