The role of molybdenum in steel can be summarized as improving hardenability, improving thermal strength, preventing temper brittleness, improving remanence and coercivity, and corrosion resistance in certain media, and preventing pitting corrosion. Due to the various beneficial effects of molybdenum in steel,it has been widely used in a series of steel grades such as structural steel, spring steel, bearing steel, tool steel, stainless acid-resistant steel, heat-resistant steel (also known as heat-strength steel), and magnetic steel. Molybdenum is very effective in improving strength and toughness in cast iron. When the addition amount is 0.25% to 1.25%, it can also form pearlite matrix structure for castings with medium and large sections. Commonly used in rolls and other wear-resistant castings.
Ferromanganese is an indispensable deoxidizer and desulfurizer in the steelmaking industry. Good Steel needs deoxidation and desulfurization in the smelting process, and the use of deoxidizers will greatly increase its cost, so ferromanganese is a cheap deoxidizer, and desulfurization refers to the removal of harmful substances such as sulfur from steel, and ferromanganese can be very good. To achieve the purpose of desulfurization, effectively reduce the content of harmful elements in the steel, and improve the quality of the steel.
Specifications and particle size: natural block, 10-100mm, powder or customized according to customer requirements.
Packaging: ton bag packaging (1000kg/bag) or customized according to customer requirements
Steel industry: Ferromanganese is an indispensable deoxidizer and desulfurizer in the steelmaking industry. Good steel needs to be deoxidized and desulfurized during smelting, and the use of deoxidizers will greatly increase its cost. Therefore, ferromanganese is a cheap deoxidizer. Desulfurization refers to the removal of harmful substances such as sulfur in steel. ferromanganese can well achieve the purpose of desulfurization, effectively reduce the content of harmful elements in steel, and improve the quality of steel.
Silicon manganese alloy is used for steelmaking. The melting points of the deoxidized products MnSiO₃ and Mn₂SiO₄ are 1270°C and 1327°C respectively. They have the advantages of low melting point, large particle size, easy floating, and good deoxidation effect.
Specifications and particle size: natural block, 10-100mm, powder or customized according to customer requirements.
Packaging: one metric ton in a large bag, or according to customer requirements

Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy smelted in an electric furnace with coke, scrap steel, quartz (or silicon dioxide ) as raw materials. Metallurgical manufacturers provide four grades of ferrosilicon, 75#72#70#65#, with favorable prices, and can provide natural blocks, standard blocks, granules, powders and other processing particle sizes according to customer requirements.
Specifications: 0.1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm or customized
Packaging: Waterproof, woven bag ton packaging (1000KG per bag)
65 Ferrosilicon is mainly an iron alloy composed of iron and silicon. Since silicon and oxygen are easily combined into silicon dioxide, ferrosilicon is often used as a deoxidizer in steelmaking. The oxidation reaction itself is an exothermic reaction. Can increase the temperature of molten steel. At the same time, ferrosilicon can also be used as an alloying element additive, which is widely used in low-alloy structural steel, spring steel, bearing steel and electrical silicon steel. At the same time, ferrosilicon is often used as a reducing agent in ferroalloy production and chemical industry.
Standard block: generally 10-100mm.
Ferrosilicon particles: 1-3mm, 3-8mm, etc.
It is used as an inoculant and a nodularizing agent in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, has excellent casting properties and much better shock resistance than steel. Especially ductile iron, its mechanical properties are comparable or close to steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of ductile iron, ferrosilicon is an important inoculant (helps to precipitate graphite) and nodularizer.
Ferrochrome is an iron alloy composed of chromium and iron. It is an important alloy additive in steelmaking. High carbon ferrochrome is made from chromite and silicon as slag flux. It is a solid solution of chromium, iron and carbon, a complex compound of chromium, iron and carbon.This product is one of the most common ferroalloys and has the characteristics of high strength, corrosion resistance, wear resistance, high temperature resistance and oxidation resistance.
Specifications: 0-10mm, 10-50mm, 10-100mm or customized according to customer requirements.

The addition of chromium to steel can significantly improve the oxidation resistance of steel and increase the corrosion resistance of steel. Chromium is contained in many steels with special physical and chemical properties. Chromium in steel is added with ferrochromium. High carbon ferrochromium is used as alloying agent for ball steel (0.5%～1.45%Cr), tool steel, die steel (5%～12%Cr) and high speed steel (3.8%～4.4%Cr), which can improve the quenching of steel. permeability, increase the wear resistance and hardness of steel.
FeMo is an iron alloy composed of molybdenum and iron, generally containing 50%-70% molybdenum, and is used as an alloying additive in steelmaking. Ferromolybdenum is an alloy of molybdenum and iron. Its main use is as a molybdenum additive in steelmaking. Adding molybdenum to steel can make the steel have a uniform fine grain structure, improve the hardenability of steel, help eliminate temper brittleness, and alloys with special physical properties. Adding molybdenum to cast iron can improve its strength and wear resistance.
