Cast iron is essentially an alloy of iron and silicon, with properties controlled by regulation of silicon content, this element is present in considerable amount in all cast irons.
Specialty Silicon Briquets
Silicon Metal-99% Si
Carbon and Silicon are the main alloying elements in cast iron with amounts ranging from 2.1 to 4.0 wt % and 1.0 to 3.0 wt % respectively. Iron alloys with less carbon content are known as steel. Carbon is chiefly responsible for the broad range of mechanical properties attainable in cast iron and steel.
Low Sulfur Carbon Raisers
Petroleum Coke Carbon
Special Carbon Blends
Manganese in iron combines with sulfur to produce manganese sulfides. Additional manganese promotes the formation of pearlite and will increase strength and hardness of iron.
Low Carbon Manganese
Chromium is a strong carbide stabilizer in cast iron. Chromium acts to increase strength , hardness, resistance to wear, abrasion, and heat.
Low Carbon Ferrochrome
High Carbon Ferrochrome
Aluminothermic Chrome Metal
Used in cast iron in amounts up to 1%. It increases brinnel hardness without decreasing machinability. Thus, improved tensile strength, toughness or resistance to impact, also resistance to wear and abrasion.
Molybdic Oxide Briquets
The role of the inoculant is to produce nuclei in the liquid iron melt which enhance the graphite nucleation at very small under - coolings. This will, in turn, promote the formation of Type A graphite structure in gray cast irons, and a high number of small graphite nodules in ductile cast iron.
75% Ferrosilicon .50 ca
Superseed 50 or 75
Foundrisil 75 or 50
These products are used in certain cases or with unique casting configurations where conventional inoculants, at normal addition rates, will not work.
Magnesium ferrosilicon is used in the manufacture of ductile iron. The magnesium promotes the formation of graphite nodules giving the iron its strength and elongation.
5% Magnesium Ferrosilicon Cerium based products
Lamet Magnesium Ferrosilicon
Specialty grades of Magnesium Ferrosilicon
TopSeedR1010 Cover Alloy
Used for additional strength, promotes pearlite formations and increases strength of the iron. Also, used in Ni-resist iron applications.
Promotes the formation of pearlite in ductile iron which leads to higher strength with lower elongations.
Up to 0.10% stabilizes the pearlite preventing its decomposition to ferrite and graphite. Thus, it increases hardness and improves both strength and resistance to wear.
Used in small amounts, titanium is a potent graphitizer and grain refiner in cast iron.
