Q460GJE steel for building structure

Posted:2021-06-24 09:57:48

Q460GJE is a low-alloy high-strength steel for building structures. Q460GJE steel is pure, with low sulfur and phosphorus content, excellent welding performance, high strength, good toughness, and good surface and internal quality.

Chemical composition of Q460GJE steel plate:
C≤0.18, Si≤0.55, Mn≤1.6, P≤0.02, S≤0.015, Ni≤0.7, Cr≤0.7, Cu≤0.3, Nb: 0.015-0.06, V: 0.02-0.2, Ti: 0.010-0.03, Als≥0.015.
Remarks: Cu is a residual element; Alt can be used instead of Als, at this time Alt≥0.02; to improve performance, one or more of Nb, V, Ti can be added as needed; V+Ti+Nb≤0.22.

Q460GJE steel is suitable for manufacturing high-rise building structures, large-span structures and other important building structures.
