What elements does medium carbon ferromanganese contain?
Medium carbon ferromanganese is an alloy iron that usually contains the following elements:
1. Iron (Fe): It is the main component of medium carbon ferromanganese, usually with a content of more than 70%.
2. Carbon (C): The carbon content in medium carbon ferromanganese is relatively high, usually between 1.7% and 2.2%. Carbon is one of the main alloying elements in medium carbon ferromanganese. It can improve the hardness and strength of the alloy, and also has a certain effect on oxidation resistance and wear resistance.
3. Manganese (Mn): The manganese content in medium carbon ferromanganese is usually between 6% and 8%, and it is one of the main alloying elements of medium carbon ferromanganese. Manganese can improve the hardness, toughness and wear resistance of the alloy, and can also improve the hot working performance and corrosion resistance.
4. Silicon (Si): The silicon content in medium carbon ferromanganese is usually between 0.15% and 0.3%. Silicon has a certain effect on the grain refinement of medium carbon ferromanganese, and can also improve the strength, hardness and wear resistance of the alloy.
5. Phosphorus (P): The phosphorus content in medium carbon ferromanganese is usually below 0.1%. Phosphorus is an impurity element in medium carbon ferromanganese, which will affect the toughness and cold brittleness of the alloy.
6. Sulfur (S): The sulfur content in medium carbon ferromanganese is usually below 0.04%. Sulfur is an impurity element in medium carbon ferromanganese, which will affect the processing performance and hot working performance of the alloy.
7. Chromium (Cr), molybdenum (Mo), nickel (Ni), etc.: Under some special production conditions, medium carbon ferromanganese may also contain a small amount of chromium, molybdenum, nickel and other elements to achieve specific performance requirements.

In general, medium carbon ferromanganese usually contains the main elements such as iron, carbon, and manganese, and may also contain a small amount of silicon, phosphorus, sulfur and other alloying elements. Medium carbon ferromanganese with different compositions is suitable for different production needs and process requirements.
