EN10028-5 is a part of the European standard for steel flat products for pressure vessels, which specifies the requirements for thermomechanically rolled weldable fine-grained steels. Produced through a thermomechanical rolling process, this steel has excellent weldability and a fine-grained structure, giving it excellent mechanical properties in high-pressure and high-temperature environments. The EN10028-5 standard has strict regulations on the chemical composition, mechanical properties, manufacturing process and inspection methods of steel to ensure that its quality and performance meet the manufacturing requirements of pressure vessels and other equipment.

The chemical composition of steel under the EN10028-5 standard is mainly determined by its specific manufacturing process and use. Typically, these steels contain basic elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P) and sulfur (S). In addition, in order to improve certain properties of steel, such as mechanical properties, corrosion resistance or weldability, specific alloying elements may be added, such as chromium (Cr), molybdenum (Mo), nickel (Ni), etc.

The delivery method of EN10028-5 mainly depends on the contractual agreement between the two parties and the specific product requirements. Typically, delivery methods may include the following:

Cut delivery: According to the customer's needs, the steel can be cut into specific sizes and delivered.

Delivery as a whole piece: In some cases, the customer may require delivery of the steel as a whole piece or as a whole plate.

Delivery in heat treatment state: For steel products under the EN10028-5 standard, specific heat treatment may be required before delivery, such as normalizing, quenching and tempering, etc., to improve its mechanical properties or meet specific usage requirements.

Delivery with inspection certificate: Steel products are usually delivered with relevant inspection certificates to prove that they comply with the EN10028-5 standard and other relevant requirements.

The characteristics of EN10028-5 are mainly reflected in the following aspects:

1. EN10028-5 standard steel adopts a thermomechanical rolling process, which can make the steel have a fine-grained structure. The fine-grained structure can significantly improve the strength and toughness of steel, giving it excellent mechanical properties in high-temperature and high-pressure environments.

2.EN10028-5 steel has good weldability. This means that steel can be easily welded during the manufacturing process to meet the manufacturing needs of complex structural parts. At the same time, the quality of the welded joints is high, which can ensure the safety and reliability of the equipment.

3.EN10028-5 steel also has excellent corrosion resistance. This is due to the optimized design of its alloy composition, which enables the steel to resist erosion by various corrosive media and extend the service life of the equipment.

4. The EN10028-5 standard has strict regulations on the chemical composition, mechanical properties and inspection methods of steel. These regulations ensure the quality and performance stability of steel, making EN10028-5 steel an important choice for manufacturing high-pressure and high-temperature equipment.

Steels under the EN10028-5 standard, thermo-mechanically rolled weldable fine-grained steels, have a wide range of applications. Specifically, this steel is often used in the production of boilers, pressure vessels, heat exchangers, pipes, and other similar equipment. In addition, due to its unique thermomechanical rolling process and fine-grained structure, EN10028-5 steel also displays excellent toughness and strength, making it particularly suitable for equipment that needs to work under extreme conditions.
