The company has A283 grade C mild steel coil advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience A283 grade C mild steel coil, we have accumulated a large number of customers at home and abroad, and won unanimous praise.
API2HGr50 delivery status: steel is usually delivered in hot rolled or hot forged state. It can also be delivered in the state of heat treatment (annealing, normalizing or high temperature tempering). Annealing: The steel A283 grade C mild steel coil is heated to a suitable temperature and slowly cooled according to the heating time of different materials and specifications. Normalizing: Heat the steel plate to a suitable temperature and cool it in the air. Tempering: Keep the steel plate at an appropriate temperature for a long time while keeping it cool.
We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product A283 grade C mild steel coil annual capacity is 200 thousand tons.
S355J2 steel plate A283 grade C mild steel coil rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the A283 grade C mild steel coil single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
