We sell 420 MOD in round bar form.

420 Mod is a metal with excellent hot working characteristics, typically supplied in both bar and tube form. Its deep hardening capability and low susceptibility to cracking make it ideal for oil industry equipment and medical equipment. A few of its common uses are:

  • Pressure containing members
  • Dental and surgical instruments, such as scissors, ear pins, and rollers
  • Manufacturing molds

420 Mod steel is hardened and tempered using heat treatments and is used in both standard and CO2 environments. Its corrosion resistance is similar to 410 steel, but its increased strength and toughness make it a good material for both the oil and medical worlds.
