About silicomanganese
Silicomanganese is an alloy of manganese, silicon and iron. It adds manganese to steel and removes oxygen at the same time, which makes it the main manganese alloy for rebar and other long products.
Grades are named by their manganese and silicon content. SiMn 65/16 has about 65% manganese and 16% silicon.
Frequently asked questions
What does 65/16 mean?
The minimum manganese and silicon content, 65% and 16%. It is the most widely traded grade.
What sizing should I ask for?
10 to 50 mm suits most ladle additions. Tell us how you add the alloy and we will match the sizing and fines limit.
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.
