Factory supply 1/4 S235J2 carbon steel material 4x8 size

The company formulates appropriate S235J2 carbon steel material product internal control components, strictly controls the fluctuation range of chemical components, and ensures the stability of steel plate performance. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel. It adopts controlled heating to ensure heating time and temperature, and measures such as controlled rolling to ensure the inherent quality of the steel plate.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the S235J2 carbon steel material, alloy wear-resistant steel plate is significantly improved.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld S235J2 carbon steel material steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for S235J2 carbon steel material manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

Our company will accept the product quality objection registration record, pass it to the S235J2 carbon steel material production unit and relevant departments, and timely coordinate the supervision of product S235J2 carbon steel material quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
