Merit
Cr20Ni80 is a high grade austenitic alloy. It has good ductibility and strength at high temperature,In industrial furnace use Cr20Ni80 has many advantages due to its excellent mechanical properties in the hot state. Cr20Ni80 has superior life compared to competitive FeCrAl alloys because of the extremely good adhesion properties of the surface oxide.
Applications
Ironing machines, water heaters, resistors, plastic moulding dies, soldering irons, metal sheathed tubular elements, cartridge elements,etc.
