EN10028-2 P265GH is a material grade and designation defined in EN10028-2 standard. It is a non-alloy steel and chrome-molybdenum steel intended for use in pressure vessels, boilers and heat exchangers. The material is used in various forms such as plates and bars, and is well suited for forming and machining.
P265GH is a European specified steel for use in pressure vessels, boilers, and heat exchangers. The composition of this steel makes it ideal for applications where elevated working temperatures are the norm and the material is used by fabricators throughout the oil, gas and petrochemical industry. P265GH is a normalized carbon alloy steel and is available ex-stock from our warehouse with mill certification and stamping. This material is known for its high strength, good ductility and easy weldability, making it a popular choice for use in the fabrication of weldable pressure vessels and boilers.
P265GH is a normalised pressure vessel steel to EN10028-2. The material is designed for use in high temperatures and pressure up to 10-bar normalised. EN10028-2 specifies requirements for flat products for pressure equipment made of weldable non-alloy and alloy steels with specified elevated temperature properties. The material is used across a variety of industries and applications due to its excellent features and properties, such as being heat resistant, fire proof, and corrosion-resistant.
The chemical composition of EN10028-2 P265GH is identical to the BS 1501-3:1990 standard, which specifies the specifications for heat-resistant and corrosion-resistant steel plates. The chemical composition includes elements such as carbon, manganese, phosphorus, sulfur, chromium, nickel, and silicon, as well as trace elements such as aluminum and boron.
All of the elements used in the manufacture of this grade of steel have an important bearing on the mechanical properties of the finished product. The high levels of carbon present give the steel an enhanced strength, making it resistant to temperature and pressure fluctuations, which is a great advantage for its intended use in pressure vessels and heat exchangers.
The mechanical properties of EN10028-2 P265GH are of particular relevance when using this material in a pressure vessel or boiler. When welding the material, special attention should be paid to the weld shrinkage rate, as this is of great importance when pressure and temperature variations occur.
The weldability of EN10028-2 P265GH steel can be improved by careful control and preheating of the material. If a weld is required, particular attention should be paid to the preheating of the material beforehand to an appropriate temperature.
In summary, EN10028-2 P265GH is a well-designed material suitable for pressure vessels, boilers and other high temperature applications due to its excellent strength, toughness, corrosion resistance and weldability. With its high quality and specifications, the material provides outstanding performance in demanding conditions.
