Hot Rolled Steel Plate 1/2" x 8" x 8" Q345NQR2 tempered steel Carbon Steel

ASTM A387 steel plate is suitable for temperature range (316-593). It's high temperature performance is still the focus of attention, even if the current trend is for applications with high CVN toughness requirements. ASTM A387 steel Q345NQR2 tempered steel tends to be fin-shaped, low-silicon, low-sulfur, calcium treatment, and occasionally produced Q&T to provide the highest level of toughness.

Since it was established in 2000. Based on the domestic rich Q345NQR2 tempered steel product resources and the great steel demand of the international market, our Q345NQR2 tempered steel service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

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 Q345NQR2 tempered steel 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 Q345NQR2 tempered steel 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.

Stainless steel plate and other plates are like smelting, refining, casting, rolling, hot rolling and cold rolling is the final process steps in the manufacture of stainless steel. At present most of the world's Q345NQR2 tempered steel stainless steel factory use the AOD furnace furnace ldpe-g-nvp stainless steel production, its production accounted for about 70% of the world's stainless steel output, a VOD furnace a converter three-step method is used to produce stainless steel, its production accounted for about 20% of the world's Q345NQR2 tempered steel stainless steel production, production of stainless steel with other methods, its production accounted for about 10% of the world's production of stainless steel.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
