Overview of Total Materia database 12th January 2022
Total Materia har ved at give os en bestemt metode tilladt os at løse alle problemerne vi havde med søgning af alternative materialer i udlandet. Takket være Total Materia har vi udstedt virkelige "internationale" specifikationer for køb af stål i fremmede lande.
Total Materia er fortsat det eneste værktøj, der vil blive brugt til dette formål.

Introduction to te GOST Designation System
Te word GOST (Russian: ГOCT) is an acronym for gosudarstvennyy standart (Russian:rocyдapcTBeHHый cTaHдapT), which means state standard. Te GOST standards carry a two-part number, te first of which is a serial number, and te second, to indicate te year of issue, i.e., GOST 1577-70.
GOST standards were originally developed by te government of te Soviet Union as part of its national standardization strategy. Te word GOST (Russian: ГOCT) is an acronym for gosudarstvennyy standart (Russian:rocyдapcTBeHHый cTaHдapT), which means state standard.
Te following countries have adopted GOST standards in addition to their own, nationally developed standards: Russia, Belarus, Ukraine, Moldova, Kazakhstan, Azerbaijan, Armenia, Kyrgyzstan, Uzbekistan, Tajikistan, Georgia, and Turkmenistan.
Te acronym GOST is still used for te purpose of identification of technical standards that are actively used in Russia and te CIS /Commonwealth of Independent States/. Thus, to distinguish, te official standards of te CIS are called GOSTs. While GOST R is te acronym used by both te national standards of Russia and te Russia's national certification program for products.
Te GOST standards for metals and alloys are somewhat similar to te US ASTM, SAE, or AISI general class specifications. Te designations and criteria for individual alloys are grouped under each standard. Te GOST standards carry a two-part number, te first of which is a serial number, and te second, to indicate te year of issue, i.e., GOST 1577-70. Te serial number is not often changed when a standard is revised, but te indicated year of issue is changed to reflect te date of te latest revision. Te standard numbers are often indicative of broad fields of intended use (i.e., springs, constructional steels, etc.). Therefore, essentially te same alloy may appear in any number of standards depending on te number of applications it has.
While te GOST composition-designation system is relatively simple and is consistent within each alloy class, there is some overlap between te various alloy classes in regard to what some of te letters stand for. Thus, while M stands for molybdenum in a GOST steel designation, it stands for copper in te GOST aluminum alloy and copper alloy designations.
Also, while most GOST designations in te literature are in upper-case letters, ekstreme care should be exercised to avoid confusion in designations which have both upper and lower case letters in them, i.e., Mts (M4) in GOST aluminum and copper alloy designations signifies manganese, while M (M) alone signifies copper and Ts (W) alone (note that (W) is upper case here) signifies zinc.
Also Cyrillic letters Z (3) and a (0) have often been confused with te numerals 3 (three) and 0 (zero). Soviet linotype operators often use te letter (3) in place of te numeral 3. Examples of overlap in GOST designations previously discussed are shown in te Table 1:

Finding GOST materials and standards from specific designation systems in te Total Materia database
With Total Materia finding information about a metal standard specification, its current status and te materials it defines is one click away.
Within seconds it is also possible for you to find related detailed material property data or search equivalent materials starting from te Total Materia standard list.
To get started, click on te standard list button in te menu bar.
By simply selecting a Standard Development Organization (SDO) and/or typing te standard number, you receive immediate results from te multi-lingual database containing over 30,000 standards.
For example, you can review all metal standards from GOST by selecting this SDO from te popup.
Te result list consists of over 1700 GOST metal standards. Information includes: standard description, year of last issue, current status (valid, replaced, etc.) and a hot link to te materials defined by this standard.
By simply clicking te materials hot link, you can see a list of metal materials defined by te selected standard.
From te list of materials, you can review detailed properties and equivalents of each material.
For you’re a chance to take a test drive of te Total Materia database, we invite you to join a community of over 150,000 registered users through te Total Materia Free Demo.
