Q460GJC steel meaning: Q stands for the initials of Chinese Pinyin for yielding. The value of yield strength is 460MPa. GJ stands for the Chinese Pinyin Gaojian initials of high-performance building structural steel. C represents the quality level, B, C, D, E, such as Q460GJB, Q460GJC, Q460GJD, Q460GJE.
For the thickness direction performance steel plate, add the thickness direction performance level (Z15, Z25, Z35) after the quality level, such as: Q460GJC-Z15, Q460GJC-Z25, Q460GJC-Z35, etc. Q460GJC steel plate is a low-alloy high-strength steel, which belongs to the steel plate for building structure, referred to as high construction steel. Q460GJC is suitable for manufacturing high-rise building structures, large-span structures and other important building structures with a thickness of 6-100mm steel plate.
Delivery status: TMCP, hot rolling, normalizing, normalizing rolling, normalizing + tempering, quenching and tempering, etc. delivery status.
Q460GJC low-alloy high-strength steel plate is used to make steel for high-rise and important building structures. It is required to have high impact toughness, satisfactory strength, outstanding welding function, certain yield ratio, and thickness direction function when necessary.
