EN10028-2 P355GH is a European material standard for flat products for boiler and pressure vessel fabrication. It specifies requirements for hot rolled steel plates with improved notch toughness, intended for use in the fabrication of pressure vessels and boilers in elevated temperature service.

Chemical Composition:

The chemical composition of P355GH is carefully controlled to ensure the material's mechanical properties and weldability. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.18%

· Silicon (Si): ≤ 0.35%

· Manganese (Mn): ≤ 1.40%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.015%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.08%

· Nickel (Ni): ≤ 0.30%

· Copper (Cu): ≤ 0.30%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.03%

Mechanical Properties:

The mechanical properties of P355GH are as follows:

· Yield Strength: ≥ 355 MPa

· Tensile Strength: 510 - 680 MPa

· Elongation: ≥ 19%

· Impact Energy (Charpy V-notch test at -20°C): ≥ 40 Joules

Heat Treatment:

P355GH plates are normally supplied in the normalized condition. Normalization is a heat treatment process that involves heating the steel to a temperature above its upper critical point and then cooling it in air. This process refines the grain structure and improves the mechanical properties of the steel.

Available Dimensions:

TJC Steel Group offers P355GH plates in a wide range of dimensions to meet the requirements of various applications. The typical available dimensions are:

· Thickness: 6mm - 300mm

· Width: 1500mm - 4020mm

· Length: 3000mm - 18000mm

Low-Temperature Impact Test:

P355GH is suitable for use at low temperatures, and as such, it must meet specific impact energy requirements at -20°C. The material is tested using the Charpy V-notch test, and the minimum value for impact energy is 40 Joules.

Main Applications:

P355GH steel plates are widely used in the fabrication of boilers and pressure vessels due to their excellent mechanical properties and weldability. They are commonly used in industries such as:

· Power generation

· Petrochemical

· Chemical processing

· Oil and gas

· Food processing

· Pharmaceutical
