EN 10028 - 3 P275N steel: composition, advantages and applications

EN 10028-3 P275N is a kind of steel with specific properties and a wide range of applications. From the composition, the chemical composition of EN 10028-3 P275N mainly includes carbon (C) ≤ 0.16%, silicon (Si) ≤ 0.40%, manganese (Mn) 0.80%-1.50%, phosphorus (P) ≤ 0.025%, sulfur (S) ≤ 0.015%, etc., but also contains small amounts of chromium (Cr), copper (Cu), molybdenum (Mo), niobium (Nb), nickel (Ni), Titanium (Ti), vanadium (V) and other elements, the reasonable ratio of these elements makes EN 10028-3 P275N has a good overall performance.

EN 10028-3 P275N has many advantages. First of all, it has high strength, yield strength ≥ 275MPa, tensile strength 390MPa-510MPa, can meet a variety of engineering structure on the strength requirements. Secondly, the steel has good toughness and anti-fatigue properties, which can maintain good stability and prolong service life under complex stress conditions. In addition, EN 10028-3 P275N has excellent welding performance and is easy to process and manufacture, which can reduce production costs and construction difficulties and improve production efficiency.

In the field of application, EN 10028-3 P275N is widely used in petroleum, chemical, power station, boiler and other industries, commonly used in the manufacture of single-layer coil-welded containers, multi-layer heat-sleeve coil-welded containers, multi-layer wrapped containers, such as the second and third types of containers and low-temperature pressure vessels and other equipment and components . In addition, EN 10028-3 P275N is also used in the field of building structure and bridge engineering, which can provide reliable support and guarantee for the engineering structure.

In conclusion, EN 10028-3 P275N, with its reasonable composition, significant advantages and wide range of applications, occupies an important position among many steels and provides strong material support for the development of related industries.
