The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, s460 automotive steel coil welding seamless steel pipes for ships and petroleum cracking s460 automotive steel coil welding steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many s460 automotive steel coil welding products have been exported to the Middle East, India, Southeast Asia and Europe and America.

At present, in the iron and steel manufacturing industry, there are more and more manufacturers of s460 automotive steel coil welding, automobile steel plate, so it is very important for us to find a high-quality automobile steel plate manufacturer for cooperation. In the selection of s460 automotive steel coil welding, automobile steel plate manufacturers and products, it is better to find several companies to compare, and to summarize and select a more suitable automobile steel plate manufacturer to cooperate. We sorted out a few ways to select high-quality s460 automotive steel coil welding, automobile steel plate manufacturers, and hope to help you to purchase!

s460 automotive steel coil welding, Q345B low alloy plate performance:
1) High strength: Generally its yield strength is above 300MPa;
2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required;
3) Good welding performance and cold forming performance;
4) Low cold brittle transition temperature;
5) Good corrosion resistance.

We can cut the large steel plates s460 automotive steel coil welding by your requirements, but to the width and length your demand; we can make the surface of the cut steel plate to be bright by milling and grinding, also can make holes and make angle degrees, and can weld by your drawing. For the s460 automotive steel coil welding product thickness under 30mm, we mainly cut by laser cutting; for thickness over 30mm, mainly OXY-cut, flame cutting. The processing plates conclude cutting the larger plate into the small sizes customer demand, cut by drawing, cut to special sizes, weld the cut parts by drawing.

Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, s460 automotive steel coil welding, and can be used instead of 40CrNi steel.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
