DESCRIPTION
The most important use of ferro molybdenum is in alloy steel. Because ferro molybdenum can improve the uniform fine crystal structure of steel, expand the quenching temperature range of steel, thus affecting the hardening depth of steel. Molybdenum is often used in combination with other elements, such as chromium, nickel, vanadium, etc., to give steel a uniform fine crystal structure, improve the strength of steel, elastic limits, wear resistance and impact strength. Molybdenum is widely used in the refining of structural steel, spring bed, bearing steel, tool steel, stainless acid resistant steel, heat resistant steel and magnetic steel and a series of steel.
In addition, molybdenum applied to alloy cast iron can make gray iron grain smaller, and improve the performance of gray iron at high temperature, improve its wear resistance. Molybdenum is added to steel for alloying in the form of clumps of ferric molybdenum or molybdenum oxide.
