SUS304 is just 304 stainless
KanthalAl is FeCrAl
OCr25Al5
0Cr25Al5 is an iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1050°C (1922°F). The alloy with the characteristics of high resistivity, low temperature coefficient of electric resistance, high operating temperature, good oxidation resistance under high temperature. It can equal to FCHW1. It is widely used in industrial electric furnace, household electrical appliance and far infrared ray device.
Ni80Cr20 nichrome
Nickel-chromium alloy, nickel chromium iron alloy with high resistivity, surface oxidation resistance is good, and have higher strength at high temperature, good processability and weldability, which can be widely used in metallurgy, electrical appliances, machinery manufacturing, etc do resistance material heating elements and electrical industry.
