Silicon Manganese Chemical Composition
Impurity Elements: Carbon 1.5% - 2.0%, Phosphorus ≤ 0.30%, Sulfur ≤ 0.05%
Products Description
The chemical composition of silicon manganese alloys consists mainly of manganese, silicon, iron and small amounts of carbon and other elements. Silicon-manganese alloys usually have a high content of manganese, typically between 60 and 70 per cent, and a silicon content of between 15 and 25 per cent. In addition, the alloy may contain other elements such as aluminium and calcium. Higher levels of manganese improve the strength and hardness of the alloy, while silicon affects the heat and corrosion resistance of the alloy. Other elements may also assist in improving the properties of the alloy.
