The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy A514 grade Q QT steel plate products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of A514 grade Q QT steel plate stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.
For the selection of A514 grade Q QT steel plate, automobile steel plate products and manufacturers, we should not only check the material processing quality, but also check how the actual installation and use effect are. The comfort, bearing capacity and other indicators of the auto made of the automobile steel plates should also be considered. In addition, in choosing A514 grade Q QT steel plate, automobile steel plate manufacturers and products, it is better to find a few more companies to compare, and conclude to choose a more suitable automobile steel plate manufacturer.
A514 grade Q QT steel plate, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. A514 grade Q QT steel plate, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. A514 grade Q QT steel plate, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the A514 grade Q QT steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between A514 grade Q QT steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
