For stabilization can be used titanium or niobium or zirconium. In accordance with the relative atomic mass of these elements and a mass fraction of carbon and nitrogen should meet the following equality: Nb (mass fraction) = Zr (mass fraction) = Ti (mass fraction). Mass fraction of niobium and zirconium is determined by chemical analysis. Tantalum can replace niobium in equal amounts. Cerium is introduced in the calculation, chemical analysis is not defined in the document quality indicates its estimated value. Note — the Sign „-" means that the mass fraction of the element in the steel is not standardized and not controlled.

7.3.1.1 Elements not listed in tables 3 and DG.1 (Annex DG), does not have to be specifically added to the steel without the consent of the consumer, except in those cases when they are introduced for debugging trunks. Should be taken all precautionary measures to prevent such elements from scrap or other materials used in steelmaking. However, traces of such elements may be present in the steel while ensuring mechanical and operational properties of steel products from it.

7.3.1.2 Limit deviations in the mass fraction of chemical elements in the finished product from the limits specified in tables 3 and DG.1, are shown in table 4.

Designations: «+A» joke; «+at» — treatment on a solid solution. If heat treatment is carried out in a continuous furnace usually prefer the upper part of the target range or even higher. Cooling environment: air, furnace, water. Allowed cooling with the furnace. Sufficiently rapid cooling (use additional means of cooling fan, etc.) The recommended grain size is not larger than the numbers 5 after the heat treatment.

B. 3 Heat

Steel, are shown in table 3, thanks to their composition of the alloying elements have a high resistance to hot gases and combustion products. Such resistance and, therefore, the maximum service temperature of a material is very dependent on the conditions in which it is used. When applying the product in conditions of clean air, when mechanical loads (see table B. 3) does not have a significant impact on its service life, you can be guided by the indicative values of the maximum operating temperature given in the table B. 2.

Note that when using the material in other atmospheres the maximum operating temperature from table B. 2 cannot be applied. In these cases the rate of oxidation of the steel may increase substantially depending on its chemical composition, which will cause a significant reduction in the maximum operating temperature, for example several hundred degrees Celsius lower than the values specified in table B. 2.

Designations: «+A» joke; «+at» — treatment on a solid solution. If heat treatment is carried out in a continuous furnace usually prefer the upper part of the target range or even higher. Cooling environment: air, furnace, water. Allowed cooling with the furnace. Sufficiently rapid cooling. Note — if the products have been subjected to processing at high temperatures, heat treatment not subjected to.
