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 DIN 17155 HI pressure vessel steel sheet 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℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of DIN 17155 HI pressure vessel steel sheet steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
When using DIN 17155 HI pressure vessel steel sheet, low-alloy high-strength steel, it is desirable to take advantage of its high strength and use a thinner section, not only for saving weight but also for the economy as much as possible. However, the corrosion factor must be fully considered. The thinner the steel section, the more attention should be paid to corrosion protection. Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but in some cases, take appropriate precautions and can even be used without being coated in the atmosphere.
We are specialized in offering hot rolled ASTM A516 steel plate, which are used in various engineering applications and can be availed in various grades like carbon steel DIN 17155 HI pressure vessel steel sheet A516 Grade 60 steel plate , A516 Grade 65 steel plate, A516 Grade 70 boiler steel plate, ASTM A516 GRADE 60 plates Trippled Certified, ASTM A516 GRADE 60 Plates Dual Certified.
