Principle of surface pretreatment of EN steel grade S275J2 material

The company has EN steel grade S275J2 material advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience EN steel grade S275J2 material, we have accumulated a large number of customers at home and abroad, and won unanimous praise.

S45C steel plate chemical composition: C 0.42~0.48, Si 0.15~0.35, Mn 0.60~0.90, P≤0.030, S≤0.035, Cu≤0.30, Ni≤0.20, Cr≤0.20Mechanical properties of EN steel grade S275J2 material productTensile strength>686MPaYield strength>490MPaElongation δ5>17%Shrinkage ψ>45%Impact toughness value>78J/cm2The hardness is 201~269HB.

EN steel grade S275J2 material, Alloy plate is a steel plate with multiple uses because it has the following characteristics. First, better abrasion resistance. Alloy plate is more wear-resistant than ordinary steel plate. It does not scratch or wear, and has applications such as floor steel plate laying, steel plate wall and so on. Second, the alloy plate has higher strength. Third, the alloy plate is more resistant to high and low temperatures. Fourth, the alloy plate has outstanding corrosion resistance. As the steel laid on the ground, it must have good corrosion resistance. Because it will suffer from wind and rain for a long time, it must be very resistant, otherwise it will be damaged once it is corroded.

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 EN steel grade S275J2 material, alloy wear-resistant steel plate is significantly improved.
