A Quick Guide to Understanding the DIN 17155 19Mn6 Steel Plate Standard

If you're working with pressure vessels or exporting steel components, understanding the DIN 17155 19Mn6 steel plate standard is essential. This European specification covers steel plates used under elevated pressure and temperature—especially in the manufacture of boilers, tanks, and pressure vessels.

DIN 17155 is a German standard specifically for pressure vessel steels. The DIN 17155 19Mn6 steel plate grade under this standard is known for its good weldability, high toughness, and resistance to pressure and temperature fluctuations. It typically contains manganese (Mn), which enhances its strength and toughness.

One key point: DIN 17155 19Mn6 steel plate is normalized—a heat treatment process that improves the steel's microstructure, making it more uniform and reliable under pressure. This makes it a popular choice in critical industries like oil & gas, chemical processing, and energy.

From a technical perspective, DIN 17155 19Mn6 steel plate offers:
- Minimum yield strength: 265 MPa (thickness-dependent)  
- Tensile strength: 440–590 MPa  
- Elongation: ≥22%

In terms of documentation, suppliers usually provide EN 10204 3.1 or 3.2 mill certificates, and the material often complies with PED 2014/68/EU, making it ideal for international markets.

Understanding DIN 17155 19Mn6 steel plate means fewer surprises during inspection, smoother project execution, and better communication with overseas clients.
