This standard applies to steel and wrought iron-Nickel alloys and Nickel-based, designed for use in corrosive environments and at high temperatures.

For high-alloy steels conventionally classified as alloys, the mass fraction of iron in which more than 45%, and the total mass fraction of alloying elements of at least 10%, considering the upper limit for the mass concentration of one of the elements not less than 8% at the lower limit.

To have iron-Nickel alloys related alloy, the main structure which is a solid solution of chromium and other alloying elements in iron-based (amount of Nickel and iron over 65% at an approximate ratio of Nickel to iron of 1:1.5).

The Nickel-based alloys include alloys the basic structure which is a solid solution of chromium and other alloying elements in Nickel-based (Nickel content not less than 50%).

The standard was developed based on the requirements of international standards ISO 683−13, ISO 683−15, ISO 683−16, ISO 4955.

1. CLASSIFICATION

1.1. Depending on the basic properties of steel and alloys are divided into groups:

I — corrosion-resistant (stainless) steel and alloys, have resistance to electrochemical and chemical corrosion (atmospheric, soil, alkali, acid, salt), intergranular corrosion, stress corrosion, etc.;

II — heat-resistant (okolnostima) steels and alloys, have resistance to chemical destruction of the surface in gaseous media at temperatures above 550 °C, working in the unloaded or lightly condition;

III — heat resisting steels and alloys, able to work under load at high temperatures for a certain period of time and thus having sufficient resistance.

1.2. Depending on the structure become divided into classes:

martensitic steel with the main structure of martensite;

martensitic-ferritic steel containing in the structure other than martensite, and not less than 10% ferrite;

ferritic — steel, having a ferrite structure (without ГОСТ 5632-72 Стали высоколегированные и сплавы коррозионно-стойкие, жаростойкие и жаропрочные. Марки (с Изменениями N 1, 2, 3, 4, 5)transformations);

austenite-martensitic — steel, having a structure of austenite and martensite, the amount of which can be changed within wide limits;

austenite-ferritic — steel, having a structure of austenite and ferrite (ferrite is more than 10%);

austenitic steel having an austenite structure.

Division of steels into classes according to structural features is conventional and is produced depending on the primary structure, obtained by cooling the steel in air after high-temperature heating. Therefore, structural deviations cause zabrakovanie to serve can’t.

1.3. Depending on the chemical composition of the alloys are divided into classes according to the main constituent element:

iron-Nickel alloys;

the Nickel-based alloys.

2. BRAND AND CHEMICAL COMPOSITION

2.1. Brand and chemical composition of steels and alloys shall be as specified in table.1. The composition of steels and alloys with the use of special methods of melting and remelting must conform to the standards table.1 if the mass fraction of other elements not specified in the standards or technical conditions of steel products. Names of special methods of melting and remelting are given in note 7 of the table.1.
