Product Description

 
Product Description

Cr20Ni80 is a resistance thermoelectric alloy with stable microstructure, stable electrical and physical properties, good high-temperature mechanical properties, good cold deformation plasticity, good weldability, and no brittle fracture after long-term use. It is widely used in the manufacture of household appliances and heating elements with working temperatures below 1000ºC, and has a long service life. Due to its high nickel content, it is relatively expensive.

 

Introduction:

 

80Ni-20Cr has high nickel and chromium content and low iron content.  It has good oxidation resistance, thermal strength, and low positive temperature coefficient below 1000 ºC. At room temperature, it has high plasticity, cold stamping, and welding performance. The alloy is a single-phase austenite after solution treatment and has stable microstructure during use.

 

Cr20Ni80 implementation standard: GB/T1234-2012

 

Chemical composition:

 

C ≤0.08%;   Mn ≤0.6%;   P ≤0.02%;   S ≤0.015%;   Si:0.75-1.60%;   Cr:20.0-23.0%;   Ni:balance   Fe ≤ 1.0%   Al≤ 0.5%

 

Maximum operating temperature of the component is 1200ºC. Fast life: not less than 80h. Melting point: 1400ºC.  Density: 8.4g/cm3.  Specific heat capacity: 0.46J/(g.K). Elongation rate: ≥20

 

Tensile strength: not less than 650 Rm/MPa Thermal conductivity: 15 W/(m.K) (20ºC) Linear expansion coefficient: 18 Microstructure: austenite Magnetic: no

 

Metallographic structure of Cr20Ni80:

 

Cr20Ni80 alloy is a single-phase austenite structure

 

The application range of Cr20Ni80 is:

 

As a heating element, it is mainly used in periodic thermal treatment furnaces with a working temperature below 1000°C, such as carburizing furnaces, bell-jar furnaces, ammonia decomposition furnaces, etc.

 

2. Electric heating wire for high-end electric heating tubes and high-end household electric heaters

 

3. Resistance tape used in high-quality resistance boxes

 

It can also be used as high-quality heat-resistant steel structural components, such as high-temperature mesh belts and burners.
