TM121 Engineered Chrome Finish

TM121 Hard ChromeTM121 is a crack-free, chromium deposit offering a good corrosion resistance. Standard hard chrome has approximately 200 to 400 cracks per linear inch, allowing corrosive material through to attack the base metal.

TM121 crack-free chrome is a barrier coating — depositing somewhat in a softer and more ductile manner than standard hard chrome.

As deposited, it is matte gray but may be polished to a bright finish. It is often used in direct contact with molten glass.

Technical Advantages:

  • Barrier coating, reduces cracks
  • Soft, ductile finish
  • Matte grey finish as deposited, can be polished to a bright finish
