The qualified flat steel has sufficiently high high temperature strength and high temperature plasticity. Therefore, A514 grade E alloy steel plate flat steel is not only required to have high enough normal temperature and instantaneous high temperature tensile strength and plasticity, but also long-term strength and long-term plasticity to ensure long-term safe work at high temperatures, especially under creep leakage conditions. The product thickness is 8-50mm, width 150-625mm, length 5-15m。
The main applications of normalizing are as follows:① For low carbon steel, A514 grade E alloy steel plate. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
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. A514 grade E alloy steel plate, 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.
Our company doesn't need the cheapest quotation to choose international logistics company, but the price performance ratio will be high, the service will be good, and the transportation must be safe and punctual, which will not affect the time when the A514 grade E alloy steel plate goods arrive at the destination, and the logistics situation will be well communicated with customers in advance. Therefore, when we choose international logistics companies, we will have a look at their timeliness and service attitude in advance. It is only important to transport goods according to the requirements of customers for logistics.
It is a modern high-tech professional enterprise integrating scientific research, A514 grade E alloy steel plate production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A514 grade E alloy steel plate process technology development, technology transfer and related technical consulting and technical services.
