Vacuum melted H-11 and 440C stainless for bearings and special applications.

  1. Conditions: Cold drawn coil, cold drawn bar, centerless ground bars, precision ground blanks.
    1. CDC: Cold drawn coil.
      Drawing – Annealing – Drawing – Inspection = Black finish.
    2. CDB: Cold drawn bar.
      Drawing – Annealing – Straighten & Cut – Inspection = Black finish.
    3. CGB: Centerless ground bar
      Drawing – Annealing – Straighten & Cut – Centerless grinding – Inspection = Ground finish.
    4. Precision Ground Blanks
      Bar – cut to short lengths – precision grind +/- .0002”
  2. Size: Maximum = .520” CDB, .515” CGB (max. 12 ft. lengths).
