2Cr12NiMoWV heat-resistant steel rod

1 Introduction

Heat-resistant steel bar D2Cr12NiMoWV is a new energy saving material. Compared with ordinary steel, it has excellent properties such as high strength and high temperature property. In particular, its excellent high temperature oxidation resistance and wear resistance can be applied to steel structures with complex shapes and complex operating conditions.

2 Outstanding features

The heat-resistant steel bar D2Cr12NiMoWV contains chromium, molybdenum, nickel and vanadium, which perform differently and together form an outstanding heat-resistant performance.

⁃ Chromium can form an oxidized protective film on the surface to isolate oxygen in the atmosphere.

⁃ Molybdenum increases the strength, oxidation resistance and wear resistance of steel.

⁃ Nickel can increase the strength and toughness of steel.

⁃ Vanadium can improve the hardenability, abrasion resistance and corrosion resistance of steel.

In addition, its high nitrogen content contributes to the strength and improves the inhibitor performance of stainless steel.

3 Production technology

As a new energy-saving material, heat-resistant steel bar D2Cr12NiMoWV needs to go through complex processes from smelting to finishing before entering the market. The production process of this steel bar mainly includes smelting and casting, forging, and surface treatment. The smelting and casting process mainly forms chromium and molybdenum into a stable state. During the forging process, the hot and cold deformation of the steel bar is carried out to change its size, shape, and performance. The surface treatment process can protect the surface from corrosion and rust.

4 Application

Heat-resistant steel bar D2Cr12NiMoWV has excellent properties such as high temperature oxidation resistance and wear resistance which are suitable for many occasions. Its application scenarios include petrochemical industry, power industry, metallurgical industry and more, such as supercritical pressure boiler, ultra-supercritical pressure boiler, cryogenic liquefied gas tank and more.

5 Conclusion

Heat-resistant steel bar D2Cr12NiMoWV is a kind of new energy-saving material with excellent properties and excellent performance, which is widely used in hot environment and can greatly improve the safety and reliability of steel structures. Therefore, it is very suitable for the production of many types of equipment.

Inox 2Cr12NiMoWV is a stainless steel bar commonly used in high temperature equipment due to its excellent heat resistance.

This high temperature alloy is derived from the 12%, 12.5 chromium and 1.0 % nickel containing stainless steel. Through high temperature heat treatment, 2Cr12NiMoWV has excellent resistance to oxidation, carburization, thermal shock and embrittlement, making it suitablefor long time continuous work under 550℃. In addition to performance advantages, 2Cr12NiMoWV also features a good wear resistance and good corrosion resistance, which further increase its application scope.

Inox 2Cr12NiMoWV is mainly used in petroleum and petrochemical industries, such as fired heaters, processing pipes and gas turbines. In heat treatment processes, Inox 2Cr12NiMoWV can be applied to the processing of various kinds of furnace door liner and furnace belt. In metallurgical industries, this stainless steel rod can be used for smelting and hot working equipment, such as ladles, pressure vessels and so on.

At present, the material of 2Cr12NiMoWV stainless steel bar is produced from chrome nickel iron and Germanium atom, which is well known for its good performance in heat resistance. Besides, the bars are strictly inspected by magnetic power detector and eddy current flaw detector to meet the requirement of high quality. The final product is available in the form of hot rolled and cold rolled status.
