TM121 Hard Chrome
In short, TM121 is a crack-free, chromium deposit offering good corrosion resistance. Comparatively, standard hard chrome has approximately 200 to 400 cracks per linear inch — allowing corrosive material through to attack the base metal.
To clarify, TM121 crack-free, hard chrome is a barrier coating — depositing somewhat in a softer and more ductile manner than standard industrial 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
- MPR 1059 Nickel Chrome: (NAVAIR/NAVSEA/NAWCAD)
