Product Introduction
SS400 steel can be manufactured into various structural steel parts, it is vastly used in many different industries for a variety of applications. it is also used in many bridge construction. Buildings are frequently constructed withQ235B steel because of its high strength and toughness. Further more, SS400 steel is also used in fields of automotive, construction, heavy equipment, and oil and gas industries.Chemical Composition

Product Advantage
SS400belongs to general low carbon steel, steel product with low carbon content less than 0.3%, it is considerably soft for easy forming, machining, welding. Heat treatment has less effect on SS400 steel material. It contains some other elements including alloy element: manganese, sulfur, phosphorus and silicon. Iron and these elements together forms unique mechanical property of SS400, unlike stainless steel with nickel and chromium element, it doesn’t show good corrosion resistance. If you need corrosion resistant property, having it painted with a layer of plating is a good choice.
