17Mn4 steel plate applications and mechanical properties

Applications of 17Mn4 steel plate:
- Pressure Vessels: 17Mn4 steel plate is commonly used in the construction of pressure vessels, boilers, and heat exchangers that are subject to moderate pressures and temperatures.
- Tanks and Pipelines: It is also used for tank and pipeline construction, particularly in industries such as petrochemical, power generation, and chemical engineering.

Mechanical Properties:
- Tensile Strength: Typically in the range of 490-640 MPa.
- Yield Strength: Around 250-350 MPa.
- Elongation: Around 22%, depending on the thickness.
- Impact Toughness: Good impact resistance at low temperatures, often tested at -20°C to ensure it meets toughness requirements for pressure vessel use.

17Mn4 steel plate is a steel grade used primarily for pressure vessels and boilers in moderate temperature and pressure environments. Its manganese-alloyed composition gives it good weldability and toughness. While direct equivalents can be found in modern standards like EN 10028 (P265GH) and ASTM standards (A516 Grade 60), the material remains most commonly associated with the DIN 17155 standard.
