Q420q steel material is a kind of structural steel plate for bridges, the grades are Q420qD, Q420qE, Q420qF.Q420q steel chemical composition: C: ≤0.11, Si: ≤0.55, Mn: 1.0-1.7, Nb: 0.01-0.09, V: 0.01-0.08, Ti: 0.006-0.03, Cr: ≤0.50, Ni: ≤0.30, Cu: ≤0.30, N : ≤0.008, Al: 0.01-0.045.Steel delivery status: delivered in the thermomechanical rolling state, and the steel plate should be trimmed for delivery.
Weather-resistant steel plate refers to steel plate that is resistant to weathering and corrosion. A514 Gr E structural steel material, Weather-resistant steel plate can adapt well to the environment and is widely used in construction, bridges, roads and other fields with outstanding performance characteristics. One of the outstanding advantages of weather-resistant steel plate is its ability to adapt to a variety of different environments, whether it is in severe cold areas or tropical areas. The weather-resistant steel plate can better maintain its characteristics in various complex environment.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the A514 Gr E structural steel material steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
There is a silo technology R&D center in our company with many experts. Our technical backbones go abroad to study advanced technologies regularly to make our technology and products leading in the world. We provide our customers with A514 Gr E structural steel material high-quality steel plates, the excellent quality from specialty. With good reputation, high-quality products, strong strength, and low prices, we welcome the clients from the world to come to visit our factory.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
