According to TU 14-1-4241-87, the chemical composition is presented for steel grade Sv-01X12N6M-VI (ChS48-VI), smelted in vacuum induction furnaces. Deviations from the indicated chemical composition are permissible: for manganese ± 0.10%, for silicon + 0.15%, for molybdenum 0.20%, for nickel ± 0.20%, for sulfur + 0.5050%, for phosphorus +0 , 0050%. Other deviations are allowed upon agreement between the supplier and the customer. As agreed with the customer and controlling organizations, modifying by calculation of yttrium up to 0.10%, zirconium up to 0.10%, tantalum up to 0.10%, titanium up to 0.10%, and their content in steel by chemical analysis is not determined. The content of nitrogen in the steel is determined optionally.

Macrostructure and pollution Macrostructure of steel billets on the other 14-1-4241-87 intended for production of welding rod, check on cross microtemplate taken from a supply profile must not have podnasadochnogo looseness, fistulas, cracks, inclusions of local coarse heterogeneity (elektroprenos), inversion of the crust that are visible without using the magnifying devices. Permitted defects of a macrostructure scales GOST 10243: Central porosity ≤ 1.0 points; - point nonuniformity ≤ 1.0 points; - exudation square ≤ 1.0 points. In the metal the var (vacuum arc remelting) allowed layer-by-layer crystallization and light the path to a score of 3.
