Structural steel angles (along with other types of steel sections like A36 channels, I-beams, bulb flats and A572 Gr 42 ms steel coil) 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.
Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, A572 Gr 42 ms steel coil based on a high starting point and high technology, the company has vigorously developed various steel products A572 Gr 42 ms steel coil and deep-processed parts, steel structures, precision castings, seamless pipes.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched A572 Gr 42 ms steel coil increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of A572 Gr 42 ms steel coil during tempering, while tempering determines the performance and life of the workpiece.
Corrosion resistance mechanism of A572 Gr 42 ms steel coil, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel A572 Gr 42 ms steel coil plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
