Stainless steel fibers Basics
Ferromagnetic stainless steel fibers, electrical properties, surface treatment, friction coefficient and versatility.
1, stainless steel fibers are ferromagnetic:
As the filament diameter is reduced, its saturation magnetization is increased. As the filament diameter is reduced, increasing the content of martensite phase, characterized in diffraction peak intensity
Also significantly increased, while the grain size is reduced to a certain extent, the exchange coupling between grains make enhanced remanence material, coercivity decreased permeability increase.
Resulting in a weak magnetic austenite fiber may be due to stress-induced phase transformation from the martensitic, austenitic stainless steel fiber is the main component of iron, also may be due to the smaller diameter filament, its organization closer to ferromagnetism of iron space state within a certain range, with smaller wire diameter, magnetic increases.
8? M fiber magnetic than 20? M and 12? M fiber 3-6 times higher, 6? Magnetic m-2U fiber is less than 8? M
2, magnetic stainless steel fibers;
Annealed fibers were paramagnetic pure austenite phase is relatively weak magnetic fiber, fibrous tissue can anneal again into a single austenite.
The martensite diffraction peaks showed diminished or disappeared. Martensitic fiber magnetic strong, its strength over the nickel matrix.
3, stainless steel fiber electrical properties:
Filament diameter becomes smaller, the resistivity increases; reduce its filament diameter axial conductivity of the fibers decreases, resistance increases.
Smaller diameter, causing a phase transition, crystal sequence changes and shifts in the magnetic resistivity change impacts, and the crystals have orientation and texture phenomenon.
4, stainless steel fiber surface treatment:
Stainless steel fiber production process, copper / tie head / wear tube - drawing / annealing - acidic electrolytic separation - cleaning and drying the acid solution separation process, using Mann King DMJ03 system technology to achieve rapid release, dispersion passivation simultaneously, the finished anti- Strong corrosion antioxidant capacity.
5, stainless steel fiber surface friction coefficient:
Filament diameter becomes smaller, the friction coefficient becomes large, the performance of its special fiber functionality more obvious theory noodle spread more evenly, because of its special features, may need to change the space environment and the process of its shop system to process more good material functionality.
6, stainless steel fibers versatility:
Conductive, anti-electromagnetic waves, sound absorption, filtration, antistatic, abrasion, high temperature resistance, cutting.
