S460QL high strength steel
S460QL quenched and tempered high strength steel plate grade introduction:
In the S460QL high strength low alloy steel plate grade, "S" means that the steel is structural steel, "460" means yield strength, "Q" means that the steel is delivered in a quenched and tempered state, and "L" means that the minimum impact energy of the steel is specified to be no less than -40℃.
During the use of S460QL high strength low alloy structural steel, its strength and hardness ensure that it will not easily break or bend, which makes S460QL high tensile steel an important material for manufacturing structural parts that need to withstand heavy loads and impacts.
