JIS SM490C plates mill with state of the art manufacturing facility

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, JIS SM490C plates, S275N plate is supplied up to 250mm.

The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with JIS SM490C plates good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick JIS SM490C plates steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

After adding a small amount of niobium, vanadium and titanium to JIS SM490C plates etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
