Applications
DIN17155 17Mn4 pressure vessel steel is primarily used for the production of boilers and pressure vessels. Its high-temperature resistance, excellent mechanical properties, and good weldability make it an ideal material for these applications. It is also used in the manufacturing of heat exchangers, pipelines, and other high-pressure equipment.

Boilers and Pressure Vessels
17Mn4 is widely used in the manufacturing of boilers and pressure vessels. These vessels are used to store and transport fluids under high pressure and temperature. For this reason, the materials used in their construction must be able to withstand high pressure and temperature without distortion or failure. 17Mn4 pressure vessel steel has these properties, making it the ideal material for the construction of boilers and pressure vessels.

Heat Exchangers
Heat exchangers are devices used to transfer heat between two mediums. They are widely used in the chemical, petrochemical, and oil and gas industries. 17Mn4 is used in the manufacturing of heat exchangers due to its high-temperature resistance and excellent mechanical properties.

Pipelines
Pipelines are used to transport fluids such as water, oil, and gas over long distances. These fluids are transported under high pressure, which can cause the pipeline material to deform or fail. To prevent this, materials with high strength, good weldability, and high-temperature resistance are used. 17Mn4 pressure vessel steel has these properties, making it an ideal material for pipelines.

Advantages
The advantages of using 17Mn4 pressure vessel steel are as follows:

Excellent Mechanical Properties
17Mn4 pressure vessel steel has excellent mechanical properties, including high tensile strength, yield strength, and elongation. These properties make it an ideal material for high-pressure applications.

High-Temperature Resistance
17Mn4 pressure vessel steel has high-temperature resistance, making it an ideal material for use in high-temperature applications. It can withstand temperatures up to 600°C without deforming or failing.

Good Weldability
17Mn4 pressure vessel steel is easy to weld, making it an ideal material for the manufacturing of pressure vessels, boilers, and other high-pressure equipment.

Low-Cost
17Mn4 pressure vessel steel is relatively inexpensive compared to other high-pressure materials such as superalloys. This makes it an ideal material for manufacturers looking to reduce their production costs.

Disadvantages
The disadvantages of using 17Mn4 pressure vessel steel are as follows:

Susceptible to Corrosion
17Mn4 boiler and pressure vessel steel is susceptible to corrosion, especially in environments with high humidity, salt, or chemicals. It is, therefore, important to take proper measures to protect the material from corrosion.
