What’s the 15Mo3 material?

15Mo3 is a low-alloy steel material that is commonly used in the construction of boilers, pressure vessels, and piping systems. It is specifically designed for elevated temperature service, making it suitable for applications in power plants, refineries, and other industrial settings where high-temperature and high-pressure conditions are encountered.

Here are some key features and properties of 15Mo3 material:

1. Chemical Composition: The chemical composition of 15Mo3 typically includes carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), chromium (Cr), and molybdenum (Mo). The exact composition may vary depending on the specific manufacturing standards or requirements.

2. Strength and Toughness: 15Mo3 exhibits good strength and toughness properties, allowing it to withstand high temperatures and pressures without significant deformation or failure. It has a minimum yield strength of 270 MPa (megapascals) and a minimum tensile strength of 450-600 MPa.

3. High-Temperature Resistance: One of the primary advantages of 15Mo3 is its excellent resistance to high temperatures. It retains its mechanical properties at elevated temperatures, which is crucial for applications involving steam pipelines, superheaters, and other components in power generation and petrochemical industries.

4. Weldability: 15Mo3 has good weldability, which means it can be easily welded using conventional welding methods. However, it is essential to follow proper welding procedures and select appropriate filler materials to ensure the integrity and strength of the welded joints.

5. Corrosion Resistance: While 15Mo3 offers decent corrosion resistance, it is not specifically designed for highly corrosive environments. For enhanced corrosion resistance, additional protective measures such as coatings or lining systems may be required, depending on the application and operating conditions.

It is important to note that specific properties and performance characteristics of 15Mo3 may vary based on the manufacturing standards and heat treatment processes applied. Therefore, it is advisable to refer to the relevant material specifications or consult with the manufacturer for precise information based on your specific application requirements.

The chemical composition of 15Mo3 material typically includes the following elements:

– Carbon (C): 0.12-0.20%
– Manganese (Mn): 0.40-0.80%
– Silicon (Si): 0.35% max
– Phosphorus (P): 0.025% max
– Sulfur (S): 0.010% max
– Chromium (Cr): 0.25-0.35%
– Molybdenum (Mo): 0.25-0.35%

Please note that these values are approximate and can vary slightly depending on the manufacturing standards or specific requirements of the material. It is always recommended to refer to the relevant material specifications or consult with the manufacturer for precise information.

In China, the equivalent material to 15Mo3 is often referred to as 12Cr1MoV. It is a low-alloy steel that has similar chemical composition and properties to 15Mo3. The Chinese equivalent material is commonly used in the construction of boilers, pressure vessels, and high-temperature piping systems.

However, it’s important to note that while 12Cr1MoV is considered to be equivalent to 15Mo3 in terms of chemical composition and general properties, there may be slight differences in specific manufacturing standards or requirements. Therefore, it’s always recommended to refer to the relevant material specifications or consult with the manufacturer to ensure the precise compatibility and suitability for your specific application.
