P460NH steel plate is the European standard container steel plate, belongs to the low alloy high-strength pressure vessel steel.P460NH steel is mainly formed by adding carbide and nitride-generating elements (e.g., Cr, Mo, V, and Nb, etc.) on the basis of the C-Mn system, which has high toughness and good welding performance.
Delivery status and execution standard of P460NH steel plate:
Delivery status: Delivered in normalized condition, normalized treatment can make the alloying elements precipitate out from the solid solution with fine compound points, so that the steel plate can obtain good comprehensive performance through the role of precipitation strengthening and fine crystal strengthening. Additional requirements for flaw detection standard and flaw detection grade can be added according to the demand, but it needs to be communicated by both supply and demand sides and specified in the contract.
Execution standard: P460NH steel plate is European standard container plate, and the execution standard is EN10028-3.
Characteristics of P460NH steel plate: In the field of material science, P460NH is a precipitation hardening stainless steel with excellent high temperature performance. Through appropriate heat treatment and alloy composition adjustment, P460NH alloy has high yield strength, tensile strength and creep fracture strength, and at the same time has good low-temperature impact toughness.The manufacturing process of P460NH alloy adopts advanced melting methods, such as vacuum induction melting or electroslag remelting, to ensure the consistency and stability of its composition and organization. At the same time, according to the actual application requirements, different heat treatment processes and alloy composition can be adjusted to obtain the required mechanical properties and corrosion resistance in. Under the high temperature environment, the mechanical properties of P460NH alloy are significantly better than other similar alloys, and its yield strength and tensile strength are significantly higher than other precipitation hardening stainless steels. In addition, P460NH alloy also has good fatigue resistance and stress corrosion resistance, so that it is stable for a long time in the high temperature environment. P460NH alloy in the aerospace, petrochemical, automotive manufacturing and other fields by the use of its wide range of excellent good should be used in high. Temperature performance and good low-temperature impact toughness, P460NH alloy is widely used in the manufacture of high-temperature structural components and key parts, such as engines, gas turbines, petrochemical reactors.
