Disadvantages of stainless steel:
Cost: Stainless steel has a higher cost relative to some other metallic materials, which may be a consideration in some applications.
Weight: Stainless steel is relatively dense and therefore may not be suitable in some weight-sensitive applications.
Thermal conductivity: Stainless steel has poor thermal conductivity and has a slower heat dissipation effect than materials such as copper.
Magnetism: Most stainless steels are iron-based alloys and therefore possess some degree of magnetism, which may be problematic in some electronic devices and applications.
Difficult to machine: Stainless steel is relatively hard, so more power and more wear-resistant tools may be required during machining and forming.
