Vincent Metals sells 420F in rod form.

420F is a martensitic stainless steel that stands apart from 420 stainless steel due to its increased sulfur content and improved machinability. 420F stainless steel, also known as chromium steel, is hot worked and annealed. Metal is annealed when it is heated and slowly cooled, a process that prevents cracking. 420F’s carbon content gives it high strength despite its low corrosion resistance, and it is used in a variety of ways:

  • Cutlery
  • Dental and surgical equipment
  • Gears
  • Hand tools
  • Hydraulic press valves
