It is best to choose stainless steel hinges for your doors, cabinets, or whatever furniture you have that may need a hinge. A hinge on a door or in a cabinet is always being used. The motion of the hinge is simple; it just bends back and forth. In this repetitive motion the hinge will get scratched and scraped over time. When the hinge gets scratched the metal part of the hinge will be exposed to the air and will begin to corrode and rust.
If the hinge is rusty it will be ineffective and hinder the motion of opening and closing a door or worse, it will break apart completely. Having it made from stainless steel will prevent the rust because it has a layer of protection that prevents it from exposure to air and water and also makes it impervious to scratches. Stainless steel hinges will never rust on your furniture.
