S690 steel equivalent grades, Structural steel is a kind of steel which meets the strength of specific specifications. Structural steel can be divided into: alloy structural steel, carbon structural steel, low alloy structural steel, heat-resistant structural steel and so on. According to different uses, structural steel can be divided into construction steel and mechanical steel. Construction steel is used to build boilers, ships, bridges, workshops and other buildings. Mechanical steel is used for manufacturing machinery or mechanical parts. Mechanical steel is often used after carburizing or quenching and tempering.
