About ferromanganese
Ferromanganese is an alloy of manganese and iron. Steel makers add it to remove oxygen and sulphur and to raise strength and hardness. Almost all steel contains some manganese.
High carbon ferromanganese is the bulk grade. Medium and low carbon grades are used where carbon in the finished steel must be kept low, for example in flat steels.
Frequently asked questions
Which grade of ferromanganese do I need?
High carbon suits most long and general steels. Medium and low carbon grades are for steels with tight carbon limits, and cost more because of the extra refining.
What is the difference between ferromanganese and silicomanganese?
Silicomanganese also contains silicon, so it removes oxygen more effectively. Many mills use both, depending on the steel grade.
How is payment usually made?
By documentary letter of credit from a bank acceptable to the seller, with payment against shipping documents and the inspection certificate.
