Service

Manufacturing facilities of JSC “IOMZ” provide different types of long-length products metalworking

• Thermal processing of bars

  Thermal processing of bars: hardening, tempering, normalizing, annealing.

  — Ø12-45 mm.
  — length is 2800-11000 mm.
  

  Thermal processing — hardening and tempering:

  — of hardware made of structural steel grades and high-nickel alloys; 
  — of parts made of structural carbon and alloy steel grades.
• Centerless bars turning

  Centerless turning of bars or thick-walled round billet:
