Nickel Chrome Wire
Nickel Chrome Wire has the following characteristics:
70ni-30cr has high nickel and chromium content, low iron content, good oxidation resistance, thermal strength and low positive temperature coefficient under 1050℃. At room temperature, it has high plasticity, cold stamping and welding properties. After solid solution treatment, the alloy is monophasic austenite.
Metallographic structure of Cr30Ni70:
Cr30Ni70 alloy is single phase austenite structure
Application scope of Nickel Chrome Wire
1. As a heating element, it is mainly used in periodic heat treatment furnace with the temperature below 1050℃, such as carburizing furnace and bell jar furnace, etc. However, it is rarely selected
2. It can also be used as high quality heat-resistant steel structural parts, such as shaft type and burning frame for furnace
