TBT 09cupcrni-a steel Vs 301 Stainless Steel

EN10025-3 S275N steel is a normalized or normalized rolled weldable fine grain structural steel grade. S275N plates shall be under normalized delivery condition and be done low temperature impacting test at -20℃when rolling. If customers request the limited for some chemical compositions, such as P and S,our mill also can satisfy this strict request when processing owning to our highest technical. For the available thickness, TBT 09cupcrni-a steel, S275N plate is supplied up to 250mm.

The wear-resistant plate TBT 09cupcrni-a steel shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and TBT 09cupcrni-a steel hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

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 TBT 09cupcrni-a 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 TBT 09cupcrni-a 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.

We have a professional production team and high-quality production equipment, and we also have a great TBT 09cupcrni-a steel advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the TBT 09cupcrni-a steel production of high-quality steel plates, steel pipes and other products that meet customer requirements.

Our company will accept the product quality objection registration record, pass it to the TBT 09cupcrni-a steel production unit and relevant departments, and timely coordinate the supervision of product TBT 09cupcrni-a steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
