Docol PHS 1800M Hot Formed Steel (PHS) Description
Hot-formed steel is a type of steel that changes its structure and properties through thermo-mechanical processing (such as rolling, forging, extrusion, etc.) under high temperature. Hot-formed steel is widely used in automobile, aerospace, shipbuilding and other industries due to their advantages of high strength, good formability, and fatigue resistance. Hot-formed steel is more ductile than cold-formed steel, meaning it can deform under greater bending and tensile conditions and is more difficult to break. Therefore, Docol PHS 1800M hot-formed steel is suitable for material applications such as structural parts that need to withstand bending and deformation in use. Besides, the weldability of hot-formed steel is better than that of cold-formed steel, so Docol PHS 1800M hot-formed steel can be joined and assembled more easily.
