First, the angle of the main marine marine angle Product description: harsh working environment of the ship, galvanized angle steel prices, therefore, q345b angle, angle required performance marine materials have good toughness, high strength, good corrosion resistance, weldability and surface properties. The chemical composition of the material is not the same with ordinary angle iron. Its main purpose is: mainly used for the hull and other internal components. The main steel processing method has: rolling: The steels metal blank by a pair of gap (shapes) of rotation of the roll, the roll due to compression of the material cross-section is reduced, increasing the length of the press molding method, galvanized angle, which the production of steel is the most common mode of production, mainly used in the production of steel profiles, sheet, pipe. Minute cold-rolled, hot-rolled. Forged steel: the use of a reciprocating hammer impact force or pressure to press the blank into what we needed to change the shape and size of a pressure-processing methods. Generally divided into free forging and forging, commonly used for the production of large sections, open cross-section billet-foot steel-inch larger material. Pullout steel: is already rolled metal blanks (type, pipe, products, etc.) through the die orifice pull aside a section reduction increase the length of the working methods are mostly used as a cold. Extrusion: is placed in a sealed steel metal squeeze Jane, put pressure Hefei angle, one end of the metal is extruded from a predetermined die hole and get there with the shape and size of the finished product processing method for the production of multi-colored Metal sheet steel q345b angle, exhibition of Commerce Bo, Hefei angle provided by the Hefei exhibition Bo Trading Company. q345b angle, exhibition of Commerce Bo, Hefei angle Hefei Show Bo Trading Company (www.hfzhanbo.com) (www.hfzhanbo.com) this year introduced a new upgrade, the above picture is for reference only, please call or pictures on this page contact telephone number, to obtain the latest information, contact: Mr. Huang.
