Wire subdivides by purpose:
· for heating elements;
· for tubular heaters;
· for resistors
Fields of application
Used in the high temperatures electric furnaces,annealing and drying furnaces, different electric heating appliances.Used for producing tube electro heatings and household appliances. Having high creep resistance, ductility, stability of the form and increased term of exploitation.
Cold drawn wire is produced from the alloy gradeCr20Ni80 in soft heat treated position diameter 0.1&7.5 mm according to the standard GOST 12766.1&90.Chemical composition of Cr20Ni80 alloy should be according to GOST 10994 74.Physical and mechanical properties of Cr20Ni80 alloy are indicated in the table.
· High temperature of exploitation (1200°c) and corrosion resistance in the air, vacuum, oxide, sulfur,nitric mediums, argon, ammonia, humid air.
· News: working temperature of “Ni Cr 80 20 +” is1500°c, guarantee 10000 hours. Spiral coiling production. We produce spiral coiling“in cool”, without heating, from diameter0,1–7,5 mm, higher than 7,5 mm spiral coiling is produced “in hot”.
· Have vibration resistance and more stable in chemical&dangerous medium.
