P275NL boiler steel plate Description

P275NL boiler steel plate is a special low-alloy high-strength steel with excellent mechanical properties and corrosion resistance. P275NL boiler and pressure vessel steel has good elongation and impact toughness, and can maintain good performance in low-temperature environments. P275NL pressure vessel steel is widely used in fields such as petroleum, chemical, power, and marine engineering.

The tensile strength range of P275NL steel plate is usually between 450 - 630MPa. Tensile strength is the maximum tensile force that a material can withstand during the stretching process, reflecting its ability to resist tensile failure. The high tensile strength of P275NL pressure vessel steel plate means that it can withstand large tensile forces without breaking, making it suitable for applications that require high tensile strength.

Grade composition:
P：Typically, steel is used for pressure vessels.
275: indicates that the minimum yield strength of the steel is 275MPa.
NL: Among them, "N" represents that the steel has undergone normalizing treatment, and "L" represents that the steel has a lower impact test temperature and is suitable for low-temperature environments.

P275NL boiler steel plate Chemical composition

Grade	The Element Max (%)
Grade	C	Si	Mn	P	S	Ni	Cu	Cr	Mo
P275NL	0.16	0.40	0.8-1.5	0.025	0.008	Max 0.45	0.45	Max 0.45	Max 0.45

The total content of Cr, Cu, Mo and other elements in P275NL steel plate is also subject to certain restrictions. Generally, the total content of these elements should meet the condition of (Cr+Cu+Mo) ≤ 0.45%. The selection and precise control of these chemical compositions are crucial to the mechanical properties of P275NL steel plates

P275NL pressure vessel steel plates also need to meet some specific performance requirements, such as thickness direction performance (Z15, Z25, Z35) and flaw detection requirements (NB/T1 detection, 2 detection, 3 detection; GB/T1 detection, 2 detection, 3 detection). These requirements ensure that steel plates have good reliability and safety during manufacturing and use.
