GBT 16270 Q460C Q+T structural steel plates steel plate

GBT 16270 Q460C Q+T structural steel plates are improved in properties based on carbon steel by adding some alloy elements such as Mn, Si, Ni, Ti, V, Nb in smelting. Mn and Si increase the strength of Q460C steel. Ti, V, Nb refines the grain, and increases the toughness of Q460C steel. Adding rare earth elements are to remove S and purify harmful impurities in steel and improve the properties of steel.
