Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc, which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields Our steel products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions,A514 grade E QT steel plate.
A514 grade E QT steel plate,We are mainly engaged in corrosion-resistant steel materials and steel processing parts, the varieties include A514 grade E QT steel plate Q355NHB, Q345NS, 09CuPCrNi-A,coten-A/B,S355J0W, Q345qNHB. The application fields involve landscape gardening, outdoor structure, environmental protection equipment, railway carriage, bridge manufacturing and many other industries. The company currently has many steel extension processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment.
45# steel is commonly used medium carbon quenched and tempered structural steel. The steel A514 grade E QT steel plate is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained 45# steel normalizing can improve the cutting performance of roughness less than 160HBS,A514 grade E QT steel plate.
A514 grade E QT steel plate,S355J2 steel plate 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 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℃.
09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.
