Our company's A572 Gr 65 high strength steel 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 A572 Gr 65 high strength steel utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
Flat A572 Gr 65 high strength steel steel plate, with a small thickness of the plate. Low carbon equivalent, to adapt to automatic submerged arc welding, plasma welding and other A572 Gr 65 high strength steel welding process requirements.
For a ship, the choice of medium and thick ship plate is very important, it is an important part of the ship frame. The pressure bearing capacity of A572 Gr 65 high strength steel, medium and thick ship plates is very strong. Secondly, because it is a ship plate, it must be driven in water, so of course the corrosion resistance is better, otherwise it will bring danger to buyers. Moreover, the service life of the ship will be increased. Regular inspection of the ship plate can ensure the safety of sailing. You can also know whether the ship plate is defective, so you don't have to worry about water seepage when you sail.
A572 Gr 65 high strength steel, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.
