Magnetic stainless steel hypodermic needle for raising livestock to be processed in meat packing plants, is detectable in meat by metal detectors

摘要

Magnetic stainless steel hypodermic needle, detectable in meat, by metal detectors, is new. Magnetic stainless steel hypodermic needle, detectable in meat, by metal detectors, is new. The needle has length of 0.5-1.5 inches and gauge of 14-20. The stainless steel is ferritic stainless steel, preferably ferritic 430 stainless steel, or martensitic stainless steel preferably martensitic 420 stainless steel. The magnetic stainless steel is cold drawn from tubular stock. Independent claims are also included for the following: (a) use of magnetic stainless steel in disposable hypodermic needles; and (b) manufacture of disposable hypodermic needles.
