Silicon Manganese
Description:
Silicon Manganese Alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements. It is an iron alloy with wide uses and large output. Manganese-silicon alloy is a commonly used composite deoxidizer in steelmaking, and is also a reducing agent for the production of medium and low carbon ferromanganese and the production of metallic manganese by electrosilicothermal method.

Application:
Manganese and silicon are the main alloying elements used in carbon steel. Manganese is one of the most important deoxidizers in the steelmaking process. Almost all steel types require manganese for deoxidation. Because the oxygen product generated when manganese is used for deoxidation has a low melting point and is easy to float; High Carbon Silico Manganese can also increase the deoxidation effect of strong deoxidizers such as silicon and aluminum.
All industrial steels need to add a small amount of Ferro alloy silicon manganese as a desulfurizer so that the steel can be hot rolled, forged and other processes without breaking. Manganese is also the most important alloying element in various steel types, and 15% is also added to alloy steels. The above manganese increases the structural strength of steel. Silicon is the most important alloying element in pig iron and carbon steel after manganese.
In steel production, silicon is mainly used as a deoxidizer for molten metal or as an alloy additive to increase the strength of steel and improve its properties.
FAQ:
Q:What is silicon manganese used for?
A:Silico Manganese is used as a deoxidizer and an alloying element in steel. The standard grade Ferro Silico Manganese contains 14 to 16% of silicon, 65 to 68% of manganese and 250% of carbon. Special grades with up to 30% Si are used in the manufacture of stainless steel.
Q: What is the effect of silicon manganese?
A: Manganese and silicon have opposing effects on the carbon concentration range where peritectic behavior and shell growth non-uniformity occurs in plain carbon steels containing high levels of Mn and Si.
