Structural steel angles (along with other types of steel sections like A36 channels, I-beams, bulb flats and A514 Gr E quenched and tempered steel) are widely used in construction as a rigid reinforcing material for concrete monolithic elements of high-rise framed buildings, as well as for critical and wide-span support elements in industrial and civil applications. Angle steel bars are also used for door and window framing, arches and other architectural elements. Steel angles are also used for room decoration, as well as in the heavy machine building and furniture industries.
20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for A514 Gr E quenched and tempered steel steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.
Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous A514 Gr E quenched and tempered steel process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.
