Description

Field of applications

Used in the high temperatures electric furnaces, firingfurnaces and fire drying furnaces, different electricthermal action apparatus and for producing resistiveelements. Chemical composition, typical mechanicaland physical properties are in the table.

Advantages

• Price is lower in 3&4 times than nichrome. 
• Higher temperature of exploitation — till ***0 °Ð¡,against ***0 °Ð¡ for Cr*0Ni*0; 
• Higher fusion temperature — ***0 °Ð¡, against***0 °Ð¡ for Cr*0Ni*0; 
• Higher (1.5&2 times) term of employment at equaltemperatures in comparison with nichrome; Less density — 7.*1 g/cm3 against 8.4 g/cm3 forCr*0Ni*0, that let economize about *6% on theweight; 
• The best corrosion resistance in the air, vacuum,argon, sulfur content and carbon medium, watersteam. 
• Higher electrical resistivity — 1.*9 Оm•mm2/magainst 1.*2 for Cr*0Ni*0.

Disadvantages

• For the avoidance of micro cracks at the winding ofthe heaters technical process must be taken at tem&perature for the wire up to 3.0mm — **0 °Ð¡, for thewire 3.0&*0.0 mm — **0 °Ð¡ by diameter. 
• In the presence of vibration can be destroyed.
