Cr15Ni60

Wire subdivides by purpose:

  • for heating elements;
  • for tubular heaters;
  • for resistors;                        
  • for heat resistance elements;
  • by color of surface:              
  • with bright surface;
  • with oxide surface; 

Fields of application:

Used in the high temperatures clectric furnaces, firing furnaces and fire drying furnaces, different electric thermal action apparatus and for producing resistive elements.

Electric heating of the furnaces are for all branches of Industry, household appliances with working temperature 1100-1200 °C. Used in high temperature electric furnaces, firing and fire drying furnaces, different electric heaters having enhanced, creep resistance, ductili­ty, (including after long exploitation), stability of the form and increased term of exploitation. Technical information

Cold drawn wire is produced from the alloy Cr15N»60 grade is produced in soft heat-treated position diameter 0.1-10 mm according to the standard GBT/1234-95.

We can supply shaped and rolled section according to GBT/1234-95, calibrated bar according to GBT/1234-95, strip according to G8T/1234-95 and GBT/1234-95 and wire according to GBT/1234-95. Chemical composition of alloy Cr15Ni60 should be according to GBT/1234-95.
