EN10028-2 Alloy Steel Plate P265GH
Products Description
P265GH is one of a commonly used European and German standard grade, this steel has replaced the BS1501 and DIN17155/DIN1639 specification. P265GH is a weldable pressure vessel and boiler steel grade suited for elevated temperature service, is commonly found in the power generation, oil & gas, petrochemical and chemical industry. The number "265" represents the minimum yield strength in normalized dondition. It is available in sheet, pipe or even forging.

Other mechanical properties of P265GH
Cold bending performance: P265GH steel plates have excellent cold bending performance, which can be bent at room temperature without being easily broken.
Weldability: P265GH steel plates have good weldability and can meet various complex welding requirements.
Corrosion resistance: After special treatment, P265GH steel plates also have good corrosion resistance and can operate stably for a long time in harsh environments.
Production Process of P265GH Steel
The production process of P265GH steel mainly includes steps such as steelmaking, continuous casting, rolling, and heat treatment.
During the steelmaking process, it is necessary to control the chemical composition and temperature to ensure the purity and quality of the steel.
In the continuous casting process, the solidification rate and temperature of the steel need to be controlled to obtain good billet quality.
In the rolling process, parameters such as rolling temperature, rolling speed, and reduction need to be controlled to achieve the required size and performance of the steel.
Finally, the mechanical properties and corrosion resistance of the steel can be further improved through heat treatment processes.
Application Fields
Due to its high strength, good weldability and corrosion resistance, P265GH steel plates are widely used in the manufacture of various structures and mechanical components. Specific application fields include but are not limited to:
Pressure vessel manufacturing: Such as boilers, storage tanks, petrochemical equipment, etc., which can maintain structural stability under high temperature and high pressure.
Heat exchangers: Can be used to manufacture the shells and tube bundles of heat exchangers, playing a key role in heat energy transfer and regulation processes.
Boiler pipelines: Suitable for manufacturing various types of boiler pipeline systems, including fuel supply pipelines, water cooling pipelines, etc.
Oil and gas industry: Widely used in the manufacture of equipment in the fields of oil and gas exploration, transportation and processing, such as oil pipelines, gas storage tanks and oil drilling platforms.
Power industry: Can be used in the manufacture of boilers and pressure vessels in power plants, which are used to generate high-temperature and high-pressure steam to drive steam turbines for power generation.
