Supply Ferromolybdenum with low price

Submitted by admin on Sat, 12/29/2018 - 09:01


Ferromolybdenum is an iron alloy composed of molybdenum and iron, generally containing 50-60% of molybdenum and used as an alloying additive for steelmaking.

Ferromolybdenum is an alloy of molybdenum and iron, and its main use is as an additive for molybdenum in steel making. The addition of molybdenum in steel allows the steel to have a uniform fine-grained structure and improve the hardenability of the steel, which is beneficial to eliminate temper brittleness.
