Gosts of steels
Gosts of steels
GOSTs of steels are the main categoryState standards, used since the times of the USSR. They are adopted by the Interstate Council for Standardization, Metrology and Certification. To date, GOSTs are normative non-legal acts.
History of GOSTs
State standards adopted up to1996, were considered normative legal acts, and therefore manufacturers were obliged to apply them in the areas defined by the preamble of a certain standard. However, after 1996, for the documents adopted at that time, normality ceased to be mandatory. Currently, any document acquires the status of a normative legal act only after passing registration at the Ministry of Justice. The most popular classifier of state standards to this day is the so-called " Classifier of State Standards of the USSR ". It is strictly hierarchical, and its alphanumeric code system consists of three to four levels. The first section is 19 letters of the Russian alphabet, while the second level (class) and the third level (group) are digital levels. The fourth level or subgroup can add after the point.Application of GOSTs to steels
Steel rolled products are represented by the following GOSTs: GOST 2590-88 (rolled steel hot-rolled round), GOST 5781-82 (hot-rolled steel for the reinforcement of reinforced concrete structures), GOST 10884-94 (reinforcing steel thermomechanically strengthened for ferro-concrete), GOST 2591-88 (hot-rolled square steel rolling), GOST 8559 -75 (square calibrated), GOST 103-76 (hot-rolled steel strip), GOST 82-70 (rolled steel hot-rolled universal wide-band). Forged steel (square and round), as well as alloys and high-alloy steels go under GOST 1133-71 and GOST 5632-72 respectively. Sheet and rolled steel is represented by the following GOSTs: GOST 19903-74 (hot-rolled steel), GOST 19904-90 (cold rolled steel), GOST 8568-77 (steel sheets with lenticular and rhombic corrugation), GOST 6009-74 (hot rolled steel strip), GOST 16523-97 (rolled sheet of carbon steel for general use), GOST 14918-80 (galvanized sheet), GOST 24045-94 (sheet steel profiled), GOST 19281 (hot-rolled low-alloy sheet ny). Wire rod and wire are represented by GOSTs: GOST 30136-94 (carbon steel wire of ordinary quality), GOST 2246-70 (steel welding wire), GOST 3282-74 (low-carbon steel wire), GOST 6727-80 (cold-drawn steel wire for low-carbon steel reinforced concrete structures), GOST 7348-81 (wire for prestressed reinforced concrete structures), GOST 7372 (wire rope wire), GOST 9389 (carbon steel spring wire).
