Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and EN 10025 S420ML steel heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported EN 10025 S420ML steel to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

A572-50 (A572 Grade 50) plate has a higher yield and tensile strength than A36 plate, combined with a lower weight. This steel is a high strength, low alloy steel plate. It offers an optimum combination of strength, weldability and notch toughness. EN 10025 S420ML steel Applications include: bridges, buildings, automotive and truck parts, railroad cars, cargo containers, tote boxes, construction equipment, structural tubing, lighting standards and transmission poles.

Our company provides EN 10025 S420ML steel, A302 gr. B boiler plate for customers all over the world, which is used for pressure vessels, boilers, tanks and heat exchangers in oil and gas projects. The boiler steel plate of ASTM A302 grade B /A302 gr. B can be rolled with a maximum thickness of 300 mm, and the steel performance, including mechanical properties and chemical composition, can be guaranteed to fully comply with ASTM A302 / A302M standard.

Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel, EN 10025 S420ML steel.

EN 10025-2 is standard for hot rolled products of structural steels. EN 10025-2 steel grades are EN 10025 S420ML steel, S235JR, S235J0, S235J2 (S235 series); S275JR, S275J0, S275J2 (S275 series); S355JR, S355J0, S355J2, S355K2 (S355 series); and S450J0. The numbers 235, 275, 355, 450 indicates the min. yield strength for thickness ≤16mm. For example, when the thickness ≤16mm, the min. yield strength for S235 series steel is 235Mpa, S275 series steel is 275Mpa, S355 series steel is 355Mpa, and S450J0 steel is 450Mpa.

Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to EN 10025 S420ML steel customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
