Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to materials and properties. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, A709 grade HPS50W bridge steel plate, welding gas cylinder and pressure vessel steel, pipeline steel, etc. We adhere to the tenet of "customer first, quality assurance and good reputation", and always provides high-quality products for our customers.
The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy A709 grade HPS50W bridge 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 A709 grade HPS50W bridge 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.
Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel A709 grade HPS50W bridge steel plate. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect. The CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting of medium and thick plates. Compared with other similar thermal cutting methods, the CNC flame cutting machine has the characteristics of high cutting quality, good cutting surface perpendicularity, and large cutting thickness.
For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In A709 grade HPS50W bridge steel plate, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.
The company's after-sales service team is a high-quality professional team. Most after-sales employees have rich service experience and have reached the level of after-sales engineer. The after-sales department implements the after-sales personnel responsibility system and a 24-hour response mechanism. The company's advanced customer relationship management system provides customers with "standardized and streamlined services". A sound customer relationship maintenance system, and a "one-stop" customer satisfaction tracking system, all reflect our strong after-sales service guarantee.
