What is requirement for surface of JIS SS400 plates

Q420q material is a kind of structural steel plate for bridges, and there are three quality levels Q420qD, Q420qE and Q420qF. When the Q420q plate is required to have the performance in the thickness direction, the symbols Z15, Z25, Z35 representing the performance level in the thickness direction are added after the above-mentioned grades. Namely Q420qDZ15, Q420qDZ25, Q420qDZ35, Q420qEZ15, Q420qEZ25, Q420qEZ35, Q420qFZ15, Q420qFZ25, Q420qFZ35.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The JIS SS400 plates metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other JIS SS400 plates alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary JIS SS400 plates carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.
