EN steel grade S235JR plates carbon steel elongation

Q355NH steel plates and sheets with atmospheric corrosion resistance are mainly used for vehicles, bridges, containers, buildings, towers, and other structures. Weather-resistant steel can be used to make bolted, riveted and welded structural parts. We can also slit and sheet Q355NH (Equivalent A588 steel) to any weight and size for immediate delivery. Our EN steel grade S235JR plates, Q355NH weathering steel plates are produced with thickness up to 100mm.

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and EN steel grade S235JR plates resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, EN steel grade S235JR plates new materials, and promotes the competition of enterprises Struggle.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the EN steel grade S235JR plates metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between EN steel grade S235JR plates strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the EN steel grade S235JR plates, stainless steel from corrosion.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel EN steel grade S235JR plates products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
