355NL1steel under EN10028-3:2003 is a common boilerplateproduct. It is a normalised, fine-grained steel grade. It is commonly used in the fabrication of pressure vessels and boilers.P355NL1 tensile strength Rm630-450MPa, yield strength: 355-295MPa, elongation after fracture 21-22%
P355NL1 steel plates mechanical properties:
P355N tensile strength (σb / MPa): 490-630
P355N yield point (σs / MPa): ≧ 355
P355N elongation after breaking (δ5 /%): ≧ 22
P355N Impact work Akv (J): -20 ≥ 30
Evaluation of P355NL1 steel resistance to hydrogen-induced cracking:
The P355NL1 steel plate resistance to hydrogen-induced cracking assessment test shall be performed in accordance with EN10229. A test solution (PH 3) or B test solution (PH 5) and the corresponding acceptance standard can be selected.
HIC test acceptance level: The acceptance level is divided into level I, level II, level III, CLR% crack length ratio, CTR% crack thickness ratio, and CSR% crack sensitivity ratio.
Main uses of P355NL1 steel plate:
P355NL1 steel plate is used in chemical, power station, boiler and other industries for making reactors, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes for hydropower stations, and turbines Equipment and components such as volutes.
