Properties of 16Mo3 steel

16Mo3 steel is an alloy steel with several key properties that make it an ideal material for specific applications. Its main mechanical and physical properties include:

Heat resistance

16Mo3 material exhibits excellent heat resistance, making it suitable for use in high temperature environments such as boilers, heat exchangers and other thermal systems. Thanks to its ability to withstand temperatures up to 580 °C, it retains its mechanical properties even when exposed to high temperatures for long periods of time.

Resistance to corrosion

The molybdenum content of 16Mo3 steel increases its resistance to corrosion, particularly in environments where chemical reactions occur and acidity is present. This makes it an ideal material for the chemical and petrochemical industries.

Mechanical properties

16Mo3 steel has good strength and toughness. Its minimum yield strength is 275 MPa and its tensile strength is between 440 and 590 MPa. These properties ensure sufficient strength and resistance to mechanical stress and wear.

Weldability

One of the advantages of 16Mo3 steel is its good weldability. This allows easy joining of individual parts without loss of mechanical properties and material integrity. This makes it possible to use it even in demanding constructions and applications.

Chemical composition of 16Mo3 steel

The chemical composition of 16Mo3 steel is a key factor that affects its properties and application. This steel is alloyed, which means that in addition to iron, it contains specific amounts of other elements that improve its performance characteristics.

The main components include:

Carbon (C): 0.12–0.20 %
Manganese (Mn): 0.40–0.90 %
Silicon (Si): 0.35 %
Phosphorus (P): max. 0.025 %
Sulphur (S): max. 0.020 %
Molybdenum (Mo): 0.25–0.35 %
Chromium (Cr): 0.30 %

These elements contribute to excellent heat resistance, mechanical properties and resistance to chemical stresses. The molybdenum content is particularly important for increasing resistance to corrosion and thermal stress.

Applications of 16Mo3 steel

16Mo3 steel is used in many industries due to its specific properties. The main areas of application include:

Energy industry

Due to its high heat resistance, 16Mo3 steel is widely used in the manufacture of boilers, pressure vessels, heat exchangers and other energy system components.
