Product Advantage

Q235Bbelongs 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 onQ235B 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 Q235B, 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.
