15Mo3 Steel — Performance, Characteristics and Application Value

15Mo3 is an alloy structural steel, commonly seen in industrial applications related to high-temperature environments. Conceptually, by adding a certain proportion of alloying elements such as molybdenum to the steel, it changes the 组织结构 of the steel, thereby endowing it with special properties.

In terms of characteristics, 15Mo3 is most prominent for its high-temperature oxidation resistance and thermal strength. In a high-temperature environment, it can effectively resist oxidation, delay the loss of the steel surface due to high-temperature oxidation, and prolong the service life. The thermal strength allows it to maintain a certain strength at high temperatures and not quickly soften and deform due to temperature rise, ensuring the structural stability under high-temperature working conditions. At the same time, its welding performance has been optimized. When performing connection operations such as pipeline welding, it can be well fused to ensure the strength and sealing of the joint.

In the application scope, 15Mo3 is mainly used to manufacture components of boilers and pressure vessels, such as the heating surface pipelines of boilers and the cylinder parts of pressure vessels (under the conditions of meeting the design temperature and pressure). In the heat exchange pipelines of some industrial heating equipment, 15Mo3 steel is also used. Utilizing its high-temperature resistance performance, it realizes efficient heat transfer and medium transportation.
