How to distinguish hot rolled xar 400 steel material and cold rolled steel by naked eyes
Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and xar 400 steel material heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported xar 400 steel material to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
The strength indexes of xar 400 steel material pipeline steel mainly include tensile strength and yield strength. At the same time, the yield strength ratio (yield strength to tensile strength ratio) of pipeline steel is also required, which is generally in the range of 0.85-0.93. Pipeline steel shall have enough high impact toughness (crack initiation and crack arrest toughness). For the base metal, when the toughness of the xar 400 steel material material meets the requirements of crack arrest, its toughness generally can also meet the requirements of crack prevention.
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 xar 400 steel material 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 xar 400 steel material 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 xar 400 steel material 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.
Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used xar 400 steel material, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.
S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. xar 400 steel material, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
The xar 400 steel material pressure vessel steel plates are our featured products.
