Marking low-alloy structural steel
Electrovek-steel company offers to purchase at affordable prices from the manufacturer sheet and bulk rolling low-carbon low-alloy steels, which are used in the manufacture of welded structures. The supplier guarantees prompt delivery of rolled metal to any point specified by the customer.
Grades of heat-resistant steels of this category
High -temperature low-alloy steels have high technical strength, which persists for a long time at high loads, as well as at elevated temperatures (up to 300… 350 0 С). The heat resistance of steel is estimated from the value of the creep limit.
One of the most popular brands of steels of this type are brands 15ХМА, 15М, 20ХМФЛ, 20ХМА. After welding, the heat treatment of such steels — quenching and tempering — = are mandatory.
Among the steels of this group are also steel grades 12Х2МФСР, 12МХ, 15ХМФКР, 15Х2М2ФБС, 15Х5, 12Х1МФ, 12Х2МФБ, 18Х3МВ, 15Х5ВФ, 15ХМ, 15Х1М1Ф, 16ГНМ, 15Х6СЮ. Some of these steels are manufactured according to the specifications of the metallurgical enterprises.
Buy alloyed low-carbon steel, designed for the production of welded structures, at affordable prices from the manufacturer offers the company Elektrovek-steel. The supplier guarantees timely delivery of rolled metal to any point set by the customer.
Grades of structural steels of this category
Such steels are mainly used in construction. For example, for the construction of high-rise buildings, grades of 14ХГС, 10Г2СД, 12ХГН, НЛ2, 09Г2ДТ, НЛ1, 10ХСНД are used, the carbon content of which does not exceed 0.25%. The steels are supplied mainly in the form of hot-rolled sheet products. Among the components of such steels, which are found most often — copper, nickel, manganese, titanium, chromium. After welding in the steels of this group, the grain sizes increase, so after welding parts and finished structures are subjected to high tempering. Hardening of such steels is carried out with reduced cooling rates.
Steel grades of this group include the following steels: 09G2S, 10G2BD, 10G2B, 10GT, 10HGSN1D, 12G2B, 10X2M1, 10GS2, 12GN2MFUYU, 12X8, 10G2S1D, 15G2SFD, 15G2SF, 08G2S, 14G2, 10HSND, 14HGS, 10HNDP, 12G2SMF, 5G2AFD1, 15ГС, 12ГС, 16ГС, 14Г2АФД, 15ГФД, 16Г2АФД, 15ГФ, 14Г2АФ, 17Г1С, 15ХСНД, 16Г2АФ, 09Г2Д, 06ХГСЮ, 09Г2, 18Г2С, 20Х2Г2СР, 1Х2М1, 27ГС, 16Д, 18Г2АФД, 20ГС2, 20ГС, 18Г2АФ. Some of these steels are smelted according to the technical conditions of the enterprises.
Electrovek-steel company offers to buy low-carbon alloy steels for welded structures at economically favorable prices from the manufacturer. The supplier guarantees the timely delivery of products to any point specified by the consumer.
