EN10025-3 S420N material is a welded low alloy steel grade. Its mateiral number is 1.8902. This steel shall be done low temperature charpy V impacting test under EN10025-3 standard, the temperature shall be -20℃, and the impacting energy shall be min 27J. For RINA FH36 ocean engineering steel, S420N steel plate quality, our company will supply various testing for our clients like size and quantity checking, the chemical analysis, ladle analysis, tensile test, impact test, and ultrasonic testing.
Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional RINA FH36 ocean engineering steel production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of RINA FH36 ocean engineering steel leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick RINA FH36 ocean engineering steel steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.
Oxygen is a harmful element in RINA FH36 ocean engineering steel steel. With the increase of oxygen content, the strength of RINA FH36 ocean engineering steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of RINA FH36 ocean engineering steel steel.
