Ferromolybdenum (FeMo)
Molybdenum source for strength and elevated-temperature properties in cast iron and steel.
Ferromolybdenum is an alloy with roughly 60-70 percent molybdenum. It is used in alloyed cast iron and steel to increase strength, hardenability and elevated-temperature properties. Molybdenum also reduces temper embrittlement.
Because the alloying element is costly, additions are calculated precisely and are effective at low levels (about 0.2-1.0 percent Mo). Its high melting point means it should be added early in the charge and in a suitable grain size.
Residuals such as sulphur, phosphorus and copper can accumulate in the casting even at small addition rates, so the analysis certificate should be checked.
