nm500 grade material Material Specification
Weathering steel is mainly used in railway, vehicles, bridges, towers and other steel structures exposed to the atmosphere for a long time. Weathering steel is used to make structural parts such as containers, railway vehicles, oil derricks, seaport construction, oil production platform and containers containing hydrogen sulfide corrosion medium in chemical petroleum equipment Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, which benefits the weathering steel component manufacturers and users,NM500 grade material.
Just as , the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed,NM500 grade material.
NM500 grade material,The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.NM500 grade material
