ST 52-3 Channel Steel Characteristic and Unique Application

St52-3 Channel Steel is most normal used among all kinds of low alloy steel grades. It is equal to Chinese steel grade Q345B, low alloy high strength steel plate. With its low carbon equivalent, it possesses good cold-forming properties. The ST 52-3is supplied in normalized or control-rolled condition.

ST 52-3 steel equivalent grade:
