Nickel chromium (iron) heating wire/strip is an austenitic nickel chromium (iron) alloy with a maximum operating temperature of 1050-1250 ° C. This alloy has the characteristics of high electrical resistivity, good oxidation resistance, and good morphological stability. Good ductility and weldability after use. Widely used as electric heating elements in household appliances and industrial furnaces. The maximum operating temperature of Cr20Ni80S is 1200 ℃. This alloy has high electrical resistivity, good oxidation resistance, and good deformation resistance. Compared to traditional Cr20Ni80, it has a longer service life. Can be used for heating elements in household appliances and industrial furnaces.
