15CrMo alloy angle steel is a low-alloy structural steel containing chromium (Cr) and molybdenum (Mo) as its main alloying elements. It features excellent high-temperature strength, oxidation resistance, and corrosion resistance, making it well-suited for high-temperature, high-pressure, and corrosive environments. Below is an overview of its major application fields:
1. Petrochemical Industry
(a) High-temperature and high-pressure equipment:
15CrMo alloy angle steel is widely used in the manufacture of reactors, heat exchangers, towers, and other petrochemical equipment that operate under extreme conditions. Its superior creep resistance and corrosion resistance ensure safe and long-term operation.
(b) Pipeline systems:
In petrochemical transport pipelines, 15CrMo alloy angle steel is used for high-pressure and high-temperature transmission lines, providing reliable performance for transporting corrosive or high-energy media.
2. Power Generation Industry
(a) Boiler components:
Commonly used in superheaters, reheaters, water-cooled walls, and other boiler parts, 15CrMo alloy angle steel maintains high mechanical strength and oxidation stability under continuous exposure to high temperatures and steam pressure.
(b) Steam turbine parts:
In steam turbines, this alloy is utilized in the production of high-temperature steam pipes, valves, and other key components, ensuring durability and dimensional stability under cyclic thermal stress.
3. Fertilizer Industry
Synthetic ammonia equipment:
During ammonia synthesis, equipment must endure high temperature, high pressure, and corrosive media. 15CrMo alloy angle steel is used for reactors, converters, and heat exchangers in synthetic ammonia plants, enhancing both safety and production efficiency.
4. Heat Treatment Equipment
(a) Industrial furnaces:
15CrMo alloy angle steel is suitable for fabricating furnace frames, furnace doors, and thermocouple protection tubes, offering excellent heat resistance and structural stability.
(b) Heat exchangers:
It is also used for tube sheets and tube bundles in high-temperature heat exchangers, providing strong resistance to thermal fatigue and oxidation.
5. Aerospace and Shipbuilding
(a) Aerospace applications:
In aircraft engines, 15CrMo alloy angle steel can be used for non-critical high-temperature components such as combustion chambers and turbine casings. While advanced superalloys are often preferred for critical parts, 15CrMo remains valuable in secondary applications.
(b) Marine engineering:
In shipbuilding, 15CrMo alloy angle steel is applied to boiler structures and steam pipelines, ensuring durable, high-temperature resistance for marine power systems.
6. Other High-Temperature and High-Pressure Equipment
(a) Metallurgical and heat treatment furnaces:
Used to construct furnace bodies, structural supports, and heat-resistant components capable of withstanding prolonged thermal exposure.
(b) Chemical pipelines and valves:
In chemical processing plants, 15CrMo alloy angle steel is commonly used for high-pressure pipelines and control valves, guaranteeing safe transport and operation in aggressive chemical environments.
Summary
15CrMo alloy angle steel integrates strength, toughness, and thermal stability with superior resistance to oxidation and corrosion. Its versatility across the petrochemical, power, fertilizer, aerospace, and shipbuilding industries makes it an essential material for high-temperature, high-pressure structural applications.
