The CHINA UNITED IRON AND STEEL LIMITED is the well-known firm for the trading of S420N steel plates. We are the leading manufacturers and traders and suppliers of industrial products and structural steel plates. We are providing a substantial supply of S420N steel plates all over the world. We care for the quality concern and time of our precious customers. We provide highly efficient steel plates with large time durability. We are also known for our before time delivery services in all the types of land areas and also in the marine industries.
The S420N steel plates are the large dimension steel plates having higher strength and low alloy structure. This product is having the higher tensile strength and higher yield strength. These plates are also suitable for welding and machining as it ensures the high level of strain. These plates are also heat resistant and can also resist all types of corrosive materials.
These steel plates are having many different features like they have high strength and high performance. These plates are being processed in the quenching process. These plates are good at hot working. This product has Maximized strength and reduced weight. These plates are good at weldability, formability, and fabrication. They are being formulated in the annealed condition which makes it more compatible with the formation and modulation.
They are having good wear and corrosion resistance. They are also having good resistance towards oxidation and atmospheric conditions. They can also resist the effect of moisture, air, and steam. They are also resistive to different chemicals and toxic gases. They can also resist pitting and cracking.
These plates undergo several tests like low temperature impacting test, ultrasonic test, cutting test and welding test, hardness test, flattening test, flaring test and PMI test. They have also certified the third party inspection, 100% high-quality raw material and it is also issued with original mill test certificate.
The china united iron and steel limited never compromises with the quality of their material. They provide the best services to our customers. We are also supplying our products at friendly prices for the satisfaction of our esteemed clients.
