Available test methods include
  • Brinell – General purpose method for ferrous materials.
  • King Brinell – A portable Brinell tester for parts too large for standard hardness test equipment.
  • Rockwell B – For non-ferrous alloys.
  • Rockwell C – Widely-used test method for heat treated steel parts.
  • Rockwell 15N – Superficial method for thin sections.
  • Microhardness – Microhardness surveys using Knoop or Vickers scale are used to determine case depth.
  • Portable Testers – For large parts or parts incompatible with standard test methods.
