3*80mm Resistohm 80 Strip for Water Heaters Application

Short Description:

Resistohm 80 is an nickel-chromium alloy for use at temperatures up to 1200°C. Heat resistant alloy applied in oxidizing atmospheres such as nitrogen, ammonia, unstable atmospheres containing sulfur and sulfur compounds. Resistohm 80 has higher heat-resisting characteristic than Iron-aluminum alloys.
