Our company's power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
The metal structure of 15CrMo steel is martensite. This material has good oxidation resistance at about 650℃, good thermal strength below 600 ℃, and good shock absorption and thermal conductivity. A514 Gr P quenched and tempered steel, 15CrMo steel is widely used in steam turbines. However, this type of steel has a greater tendency to harden and has poor welding performance. GB/T 3077-2015 15CrMo plates are supplied with 5 to 70MM thick, can be set to roll futures.
Pressure vessel plates A514 Gr P quenched and tempered steel are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing The impact temperature is normal temperature, 0 ° C, -20,A514 Gr P quenched and tempered steel.
In order to improve the corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.A514 Gr P quenched and tempered steel
A514 Gr P quenched and tempered steel,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. S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
