Q460NC steel plate use
Q460NC belongs to the bottom box gold high-strength high-structure steel plate, Q460NC steel plate implementation standard for GB/T16270 special technical conditions.
Q460NC Steel plate Introduction:
Q460NC belongs to the bottom box gold high-strength high-structure steel plate, Q460NC steel plate implementation standard for GB/T16270 special technical conditions. Delivery status: The steel plate is delivered under normal condition. The grade means: "Q" : the first letter of the steel plate yield strength "flexion"; "460" : indicates that the steel plate yield strength is greater than 460MPa; "N" : indicates the delivery status of the steel plate; "C" : indicates the quality grade of the steel plate, and the steel plate is impacted at 0℃. Q460NC steel plate thickness detection can be '1 probe, 2 probe, 3 probe' when necessary Q460NC steel plate thickness extension can be 'z15, z25, z35; The N in the Q460NC steel plate grade also represents the meaning of normalizing.
