Fe is the basis.
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.
