Grade: AISI 302
Formula: Fe/Cr 18/Ni 8
Form: Insulated Wire
Material: Stainless Steel
Commodity: Alloys
Conductor Diameter:
0.025mm
Insulation:
Polyesterimide
Insulation Thickness:
0.002mm
Polyesterimide-Insulated AISI 302 Stainless Steel Wire combines the mechanical strength and corrosion resistance of stainless steel with the high thermal stability and dielectric performance of a polyesterimide coating. This combination provides excellent performance in high-temperature, chemically aggressive, and mechanically demanding environments. Industries such as aerospace, automotive, and electronics employ it in high-reliability motor windings, sensor leads, and precision coil windings. Specific applications include high-speed aerospace actuators, downhole drilling sensors, and high-voltage instrumentation. In research, it is used to study conductor insulation performance, high-temperature electromagnetics, and advanced winding designs. The insulated wire format ensures both electrical reliability and mechanical durability in extreme operational conditions.
