Stainless Steel Needle TP304 Capillary Needle Tube For Medical Devices

Needle Tubes are normally made from a stainless-steel tube through a process known as tube drawing where the tube is drawn through progressively smaller dies to make the needle. The end is bevelled to create a sharp pointed tip letting the needle tube easily penetrate.

Stainless steel needle or hypodermic tube is a thin-walled grade designed with tight tolerances. A Stainless Steel Needle Tube is small diameter tubes that are utilized for injection under the skin. These tubes are ideal for medical applications where corrosion resistance, uniformity, and strength are of the top echelons. The Stainless Steel Needle Tubes display superior strength and have a tensile strength between 1030mpa to 1370mpa.

These tubes begin as a strip of stainless steel. They're rolled, welded, then plug drawn to its final size. This process gives tubes the appearance of being seamless, as well as holding tight tolerances on both the OD and ID. It’s commonly referred to as needle tubes.

Why are needles tubes made of stainless steel?

Traditional sewing needles are made with nickel-plated iron which tends to be brittle and will snap and break. 100% stainless steel needles never rust and are more flexible under pressure.
