Q355NH steel plates and sheets with atmospheric corrosion resistance are mainly used for vehicles, bridges, containers, buildings, towers, and other structures. Weather-resistant steel can be used to make bolted, riveted and welded structural parts. We can also slit and sheet Q355NH (Equivalent A588 steel) to any weight and size for immediate delivery. Our A709 grade HPS50W bridge steel plate, Q355NH weathering steel plates are produced with thickness up to 100mm.
The development A709 grade HPS50W bridge steel plate of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with A709 grade HPS50W bridge steel plate high-quality and efficient services, work together for win-win, and create a better tomorrow!
Nickel element is mainly used to form and stabilize the austenite structure, so that the A709 grade HPS50W bridge steel plate steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
A709 grade HPS50W bridge steel plate, Q345B steel is high strength low alloy HSLA steel. Due to the addition of alloy elements, the yield strength of Q345B and so on HSLA steel is 25% - 150% higher than that of carbon structural steel with the same carbon content. Using HSLA structural steel instead of carbon structural steel can reduce the self weight of the structure, save metal materials and extend the service life of the structure.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
