Ferro Alloy

DB Metal's Manganese Ferroalloy

The manganese ferroalloy of DB Metal is divided into FeMn and SiMn. Depending on the amount of carbon, it is also classified into High Carbon / Medium Carbon/Low Carbon FeMn and general /Low carbon silicomanganese.

※Recently, we have succeeded in developing ultra-low phosphorus carbon (ULPC) ferromanganese, low boron (LB), and low nitrogen (LN) products with extremely low phosphorus (P) and carbon components and are currently producing them.

Ferroalloy Spec

  • High carbon ferromanganese (HC FeMn)
    • As an alloy with high carbon content, it has been widely used in a steel maker.
      • To remove oxygen & sulfur and add manganese
      • To manufacture general steel plates
      • For the addition of manganese components
      • Most commonly used ferroalloy
  • Medium/low carbon ferromanganese (MC/LC FeMn)
    • This refined alloy is advantageous in carbon management due to relatively low carbon content. It is usually used in the manufacture of high-grade steel (ex: automobile, ship, etc.)
      • To remove oxygen and add manganese
      • To manufacture high-grade steel for automobile and ship
      • DB Metal has the No.1 production capacity for this alloy with advanced manufacturing technology
      • Essential in producing high-grade steel / a high demand from steel makers.

  • SiMn
    • It is commonly used by electric furnace steel makers in order to add silicon and manganese to steel.
      • To remove oxygen and sulfur/ add silicon and manganese
      • To produce section steel and reinforcing bar
  • LC SiMn
    • Containing low carbon contents, it is used to remove oxygen and add components.
      • Developed and used by DB Metal
      • To produce stainless steel and steel rods such as welding rod
      • Commonly used in making the steel which requires silicon

  • ULPC FeMn
    • ULPC FeMn is an alternative alloy of Manganese metal. It is used to make highly light but strong steel.
      • Light but strong alloy with no impurities/the highest value-added product
      • Flexible due to low carbon content
      • Good for automobile steel and the steel which is targeted to reduce noise and vibration
      • Makes a car lighter and stronger / a cost-efficient and environment-friendly product
      • Good for Oil Country Tubular Goods (OCTG) which is used in developing an oil well (petroleum or natural gas)

  • Low Nitrogen Medium / Low Carbon Ferromanganese (LN MC/LC FeMn)
    • A product with low nitrogen content
      • Nitrogen causes mechanical defects such as crack during rolling so this low nitrogen alloy has been used for decreasing defects. Rolling: A process of making reinforcing bar and sheet steel
      • Products of DB Metal
      • Increasing of high quality steel production needs more high purity manganese ferroalloy
  • Low Boron Silicomanganese (LB SiMn)
    • SiMn product lowered Boron
      • Because boron reduces weldability and creates crack, this low boron alloy has been developed for decreasing those disadvantage.
      • It is also expected that the demand for this product will increase as well as LN product
