According to TU 14-1-4241-87, the chemical composition is presented for steel grade Sv-07H22N13G5ST (ChS49), melted in a plasma arc furnace and steel grade Sv-07H22N13G5ST-Sh (CS49-Sh) electroslag remelting. Deviations from the indicated chemical composition are allowed: carbon +0.010%, manganese + 0.50%, silicon +0.30%, titanium +0.10%, sulfur + 0.5050%, phosphorus +0, 0050%. Other deviations are allowed upon agreement between the supplier and the customer. Calcium is applied to steel to 0.10%, yttrium to 0.050%, cerium to 0.20%, boron to 0.040%, the content of which is not determined by chemical analysis. Aluminum is injected into the steel with 2.20% calculated without taking into account the fumes. The aluminum content in the finished metal is not determined and the certificate is not introduced.

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 ESR (electroslag remelting) is allowed layer-by-layer crystallization and light the path to a score of 3.
