Ferro Molybdenum is an alloy which is formed by combining Iron & Molybdenum. Ferro Moly is a hardening agent & is found in many alloy steels. Molybdenum prevents corrosion in Stainless steel and when mixed with Iron, it also hardens & strengthens into austenite. The alloy is produced by heating/melting a mixture of Molybdenum Oxide & Iron. It can be produced in an Induction/Arc furnace or by aluminothermic reaction. It is added to Molten steel before casting. Ferro Molybdenum comes in many grades, but the Molybdenum content mostly varies between 60 – 75%. It is not classed as a hazardous good for transit.
