15CrMo alloy angle steel is a low alloy steel containing chromium (Cr) and molybdenum (Mo) elements. It has excellent high temperature strength, oxidation resistance, and corrosion resistance. It is widely used in engineering fields that need to withstand high temperatures, high pressure, and corrosive environments. The following is its specific application scope:

1. Petrochemical industry
(a) Reactors, heat exchangers, towers, and other equipment: 15CrMo alloy angle steel is often used to manufacture high-temperature and high-pressure equipment in petrochemical plants, such as reactors, heat exchangers, towers, etc. This equipment needs to operate for a long time in high temperatures and corrosive media. The high temperature resistance and corrosion resistance of 15CrMo can meet their use requirements.
(b) Pipeline system: In petrochemical pipelines, 15CrMo alloy angle steel is used to manufacture high temperature and high pressure transmission pipelines to ensure the safe transportation of media.

2. Power industry
(a) Boiler components: 15CrMo alloy angle steel is often used to manufacture superheaters, reheaters, water-cooled walls, and other components of power station boilers. These components need to work under high temperatures and high pressure. The high temperature strength and oxidation resistance of 15CrMo can ensure their long-term stable operation.
(b) Steam turbine components: Among the high temperature components of steam turbines, 15CrMo alloy angle steel is also used to manufacture some key components, such as high temperature steam pipes and valves.

3. Fertilizer industry
Synthetic ammonia unit: During the production of synthetic ammonia, the equipment needs to operate in high temperature, high pressure, and corrosive media. 15CrMo alloy angle steel is used to manufacture key equipment such as reactors and heat exchangers in synthetic ammonia units to ensure production safety and efficiency.

4. Heat treatment equipment
(a) Industrial furnaces: 15CrMo alloy angle steel can be used to manufacture components such as furnace frames, furnace doors, and thermocouple protection tubes of industrial furnaces to withstand high temperatures and thermal stress.
(b) Heat exchangers: In situations where high-temperature heat exchange is required, 15CrMo alloy angle steel is used to manufacture components such as tube sheets and tube bundles of heat exchangers.

5. Aerospace and Shipbuilding
(a) Aircraft engine parts: In the aerospace field, 15CrMo alloy angle steel can be used to manufacture high-temperature parts of aircraft engines, such as combustion chambers, turbine blades, etc. (although more advanced high-temperature alloys are used in more cases, it may still be used in some non-critical parts).
(b) Ship boilers and pipelines: In shipbuilding, 15CrMo alloy angle steel is used to manufacture high-temperature parts and steam pipelines of ship boilers to ensure the reliable operation of ship power systems.

6. Other high-temperature and high-pressure equipment
(a) High-temperature furnaces: Such as metallurgical furnaces, heat treatment furnaces, etc., 15CrMo alloy angle steel can be used to manufacture furnace body structural parts and heat-resistant parts.
(b) Chemical pipelines and valves: In chemical production, 15CrMo alloy angle steel is used to manufacture high-temperature and high-pressure pipelines and valves to ensure the safe transportation and control of media.
