Applications of P355GH Steel Plates

 

P355GH steel plates are widely used in industries requiring high-temperature and high-pressure resistance, such as:

  • Boilers & Pressure Vessels: Shells, drums, and heat-resistant containers.
  • Heat Exchangers & Steam Generators: Process coolers and industrial heaters.
  • Chemical & Petrochemical Equipment: Reactors, distillation columns, and piping systems.
  • High-Pressure Tanks: LPG, gas, and petroleum storage vessels.
  • These plates meet EN 10028-2 standards, ensuring stability and safety in demanding operational conditions.

 

P355GH Steel Equivalent Grades

 

Region Equivalent Grades
Europe P355N, D52-1, D52-2, E52-1, E52-2
Germany 19Mn8, StE355, E355R
Italy Fe510-1-KW
France A510 AP, FP
Sweden SS 21,06,01

Note: P355GH is also comparable to ASTM A516 Grade 70 and ASME SA516 Grade 70 for high-temperature pressure vessel applications.

 

Technical Requirements for P355GH Steel Plates

 

Our P355GH steel plates are processed and tested under strict quality control, with options including:

Heat Treatment: T (Tempered), Q (Quenched), Q+T (Quenched & Tempered)

Application

 

What is P355GH material?

P355GH steel gives optimum performance for pressurised products that must support a creep limit greater than 180N/mm2 at 400ºC. These types of steel are characterised by good weldability. They are used above all for manufacturing boilers, pressure vessels and pipes for the transportation of hot liquids.

 

What is en 10028 P355GH equivalent to?

P355GH pressure vessel steel is an equivalent to ASTM A516 Grade 70 and ASME SA516 Grade 70.

 

What is the difference between P355GH and P355NH?

P355GH: This steel is designed for high-temperature applications and is characterized by high strength at temperatures up to 500 °C. P355NH: This steel is designed for low-temperature applications and is characterized by high toughness at low temperatures.

 

What is P235gh pipe equivalent ASTM material?

P235gh grade is an alloy of European standard EN 10028-2, which is also called the A2885 grade C steel, The P235gh Equivalent Astm Material is the ASTM A285 or the A285M standard.

 

What is the yield strength of P355GH?

Carbon steels that are characterised by a greater resistance to pressure, capable of bearing significant pressure both at high and low temperatures. The yield strength ranges between 315 and 355 MPa, according to the range of thicknesses and its tensile strength goes from 510 to 650 MPa.
