     Common Low-Alloy Structural Steels in China

     

    16Mn low-alloy high strength steel is the most widely used in China. Strength is better than ordinary carbon structural steel. 

     

    Q235 height of about 20% to 30%, resistance to atmospheric corrosion 20% to 38%.

     

    15MnVN steel is most used medium level intensity steel with high strength and toughness, and good weldability and low temperature toughness, widely used in the manufacturing of bridges, boilers, ships and other large structures.

     

    If intensity level exceeds 500MPa, ferrite and pearlite structure can not meet the requirements, so the low-carbon bainitic steel come into being. With Cr, Mo, Mn, B and other elements in it, which is conducive to obtain bainite under air cooling conditions, so that a higher strength, ductility and weldability are better. The low-carbon bainitic steel is applied to manufacturing of high-pressure boilers and pressure vessels.
