P275NH high-strength pressure vessels steel P275NH boiler steel

P275NH Boiler and Pressure Vessel steel Description

P275NH pressure vessel steel is a material with excellent properties and wide range of applications. P275NH steel plate is a European standard EN 10028-3 low alloy steel plate for high temperature and high pressure vessels. P275NH boiler steel has high strength and compression resistance at lower temperatures. P275NH pressure vessel steel plate is usually used in structural engineering, storage Tanks, pressure vessels, etc., as well as for industrial applications under high temperature and pressure conditions.

P275NH boiler and pressure vessel steel is a low-alloy high-strength structural steel. It has excellent mechanical properties and good welding performance. The main components of P275NH pressure vessel steel include elements such as carbon, silicon, manganese, phosphorus, sulfur and nitrogen. The content and proportion of these elements determine the physical and mechanical properties of the material.

Performance characteristics of P275NH:

High strength: P275NH steel has high tensile strength (370 MPa to 490 MPa) and yield strength (minimum up to 275 MPa), and can maintain stable mechanical properties in high and low temperature environments.

Low temperature toughness: P275NH can still maintain good toughness in low temperature environments, allowing it to maintain excellent impact resistance in cold operating environments.

Welding performance: P275NH has good welding performance, is easy to perform welding operations, and its strength after welding is equivalent to that of the base material, meeting the manufacturing requirements of various pressure vessels.

Corrosion resistance: P275NH steel contains a certain amount of nitrogen, which can form a dense nitride layer and improve the corrosion resistance of the steel.

Good processing performance: P275NH steel can be cut, bent, formed and drilled, making it easy to manufacture pressure vessels of various shapes and sizes.

P275NH low-alloy high-strength structural steel is widely used in the following fields:

Petrochemical industry: Used to manufacture various pressure vessels, reactors, storage tanks and pipeline systems, etc., suitable for harsh environments in petroleum, chemical, fertilizer and other industries.

Energy field: In the fields of nuclear energy, thermal power generation and natural gas, P275NH is used to manufacture various pressure vessels, pipelines and structural parts, etc., to meet the requirements of high strength, corrosion resistance and low temperature toughness.

Cryogenic engineering: Because P275NH can still maintain good mechanical properties and low-temperature toughness in low-temperature environments, it is widely used in cryogenic engineering fields, such as liquefied natural gas (LNG) storage tanks and transportation equipment.

Machinery manufacturing: In the field of machinery manufacturing, P275NH can be used to manufacture various high-strength structural parts and wear-resistant parts, such as excavators, loaders and mining machinery.

Construction industry: In the construction field, P275NH steel can be used to manufacture structural parts of high-rise buildings, bridges and building supports, etc., to meet high strength and durability requirements.
