Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of A572 grade 55 ms steel coil circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and A572 grade 55 ms steel coil management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.
Tianjin warehouse mainly stores steel plates and steel pipes. The monthly replenishment is about 12000 tons. Our inventory cycle is short and flexible. Shanghai warehouse mainly stores A572 grade 55 ms steel coil ,steel plate and section steel. The average monthly purchase volume is about 15000 tons. The geographical location of the warehouse has greatly improved our performance in terms of transportation and delivery time.
The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the A572 grade 55 ms steel coil steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the A572 grade 55 ms steel coil steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.
In year 2015, we supplied 950 tons S355J0 angle steel to Egypt government. We have cooperation with local government for more than 3 years. Every year, they would order more than 3000 tons of A572 grade 55 ms steel coil steel from our company.
Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. A572 grade 55 ms steel coil, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
