Cast iron foundry refined magnesium.

According to GOST 4832−95, the content of manganese iron is divided into 3 groups: Group I ≤ 0.30%, Group II 0.30−0.50%, Group III 0.50−1.00%; the content of phosphorus is divided into 2 classes: class, A ≤0,080%, class B ≤ 0.12%; the sulfur content is divided into 2 categories: Category 1 ≤0.0050%, Category 2 ≤0.010%.

For further smelting in iron foundries in the production of castings.
