Dual Phase Low Alloy (DPLA) Steels

• Based on Mn and Si additions

  • micro structure islands of Martensite in ferrite

• Excellent mechanical properties

  • High strength (300-350MPa)
  • No yield point
  • Rapid work hardening - yield stress in formed article can be 500MPa
  • Low springback

• The high UTS/yield stress ratio means good energy absorption

  • DPLA steels used for front and rear structural members
