A633GrD steel plate is suitable for normalized high-strength low-alloy structural steel plate for tower connection or source bolt connection structure. A633GrD steel plate should be normalized: heat the steel plate to a suitable temperature that can produce austenite structure but does not exceed 1700F [925℃], and keep it at this temperature for a period of time, so that the entire A572 Gr 55 high strength steel plate can be uniformly heated, and then left in the air Cool with medium.
Q235NH corrosion-resistant steel plate full name: atmospheric corrosion-resistant hot continuous rolled steel, also known as Corden steel, widely used in: containers, power plants, chimney and railway engineering, such as large outdoor sculpture steel. The corrosion-resistant steel plate (i.e. atmospheric corrosion resistant steel) is a low-alloy steel series with low price and good quality, which is between ordinary steel such as A572 Gr 55 high strength steel and stainless steel. The corrosion-resistant steel can be continuously developed and innovated after being integrated into modern metallurgical new mechanism, new technology and new process. It is one of the series of steel with world advanced super steel technology.
S355J2 steel plate A572 Gr 55 high strength steel 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 A572 Gr 55 high strength steel 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℃.
