SA285GrC boiler steel plates are suitable for medium and low tensile strength carbon steel plates for melt welding pressure vessels.
The advantages of SA285GrC steel plate BBN Steel products:
- SA285GrC steel is pure
It has super-high-power electric stove training and perfect outside technology. The extraction rate outside the molten steel furnace reaches 92%, and the vacuum degassing extraction rate reaches 90%.
- Uniform function
Rolling is carried out on a 4200mm wide and heavy plate rolling mill equipped with hydraulic AGC automatic thickness control and laser thickness measurement system, using super-large steel ingots and thick slabs, controlled rolling and low-speed and large-reduction horizontal and horizontal rolling processes to ensure satisfactory compression Compared with the steel plate, the deformation and penetration are complete, the vertical and horizontal functions are uniform, and the internal structure is dense.
- The internal quality of the steel plate is excellent, and the ability to ensure qualified flaw detection is strong
SA285GrC steel plate can be in accordance with the winning standard (JB4730, GB/T2970), American standard (A435 , A577 , A588), Japanese standard (JISG0801, JISG0901), German standard (SEL072), British standard (BS5996), French standard (NFS04-305) And other domestic and foreign inspection standards for production inspection.
SA285GrC plate rolling processRolling system: finishing rolling reduction system: the total reduction rate of the last three passes ≥ 40%, the reduction rate of the finished product pass ≥ 10% (steel width ≥ 2200 mm or thickness ≥ 40 mm or later roll production, the finished product pass reduction is allowed Down rate decreased by 2.0%).
SA285GrC steel plate uses:SA285GrC boiler steel plates are mainly used to make fixed boilers, ship-hull boilers and other important boiler accessories, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes for hydropower stations, turbine volutes and other equipment and components .
