CARBON STEEL H BEAM Q690 HW make up the most common component of structural framing systems. They can be used to build bridges, warehouses and other large buildings, and can even be used in machinery or to frame truck beds. Beams can be positioned on their sides or at an angle and connect to columns via bolts, welds, and beam supports.

This paper details an investigation into the effect of martensite–austenite (M–A) constituent on impact toughness of intercritical heat-affected zone (IC HAZ) in CARBON STEEL H BEAM Q690 HW, a low carbon bainitic steel. Large samples with uniform microstructure similar to that of the actual IC HAZ were achieved through combinations of heat treatments. The samples were heated to temperature between 750 and 830 degree for 30 min and then quenched in water.
