What is SMA490CP channel steel equivalent steel in EN standard

After adding a small amount of niobium, vanadium and titanium to SMA490CP channel steel etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

we also provide the SMA490CP channel steel welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful SMA490CP channel steel welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

According to the data of Tianyan Inspection, recently, a series of changes have taken place in the steel e-commerce company Minmetals E-commerce Co., Ltd., and Alibaba's investment entity, Hangzhou Ali Venture Capital Co., Ltd., has withdrawn from its ranks of shareholders. Previously, Alibaba Banner held 44% of the company's shares. Minmetals E-Commerce Co., Ltd.'s business scope includes international ship management; international shipping; domestic water transportation; online trade agents; online operation of computers, metal materials, hardware, etc.

Q355NHD is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and D represents quality grade (A, B, C, D, E) composition. SMA490CP channel steel steel is an atmospheric corrosion-resistant steel plate with the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature and fatigue resistance.
