hardox 400 steel equivalent exporters in Europe

Generally, the production process of seamless steel tube can be divided into cold rolling and hot rolling. The production process of cold-rolled seamless steel tube is generally more complicated than that of hot rolling. The tube blank must be first rolled by three rolls, and then be subject to sizing test and cutting after extrusion. Then enter the annealing process. In appearance, the cold-rolled seamless steel tube is shorter than the hot-rolled seamless steel tube, and the wall thickness of the cold-rolled seamless steel tube is generally smaller than that of the hot-rolled seamless steel tube, but the surface looks brighter than the thick wall seamless steel tube, the surface is not too rough, and the diameter is not too much burr.

Q235 is a kind of carbon steel. , Q235 steel is widely used in steel structure construction because of its good toughness, good plasticity, certain elongation, good welding performance and heating performance Q235A steel plate contains C ≤ 022%, Mn ≤ 14%, Si ≤ 035%, S ≤ 0050, P ≤ 0045 Q235B steel plate contains C ≤ 020%, Mn ≤ 14%, Si ≤ 035%, S ≤ 0045, P ≤ 0045 Q235C steel plate contains C ≤ 017%, Mn ≤ 14%, Si ≤ 035%, S ≤ 0040, P ≤ 0040 Q235D steel plate contains C ≤ 017%, Mn ≤ 14%, Si ≤ 035%, S ≤ 0035, P ≤ 0035,HARDOX 400 steel equivalent.

Both parties shall confirm the material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement.
