Q355GNH weather-resistant steel, that is, atmospheric corrosion-resistant steel, is a low alloy steel series between ordinary steel and stainless steel. ASTM A709 carbon steel plate, Q355GNH alloy steel plate and sheet are mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.
Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel ASTM A709 carbon steel plate not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.
Vanadium mainly exists in the form of carbide in ASTM A709 carbon steel plate and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
