  • Detectable stainless steel needles for meat packing
    Patent number: 6599276
    Abstract: Magnetic stainless steel needles are detectable in processed meat. The previous non magnetic versions, made of 304 stainless steel, aren't. Disposable hypodermic needles made from martensitic and ferritic stainless steel are easily detectable at the smallest size. Needles are conveniently made from 420 martensitic stainless steel or 430 ferritic stainless steel.
