Cannulas, such as those needed for intravenous access, are mass-produced medical devices that are used billions of times a year. Their safe use, however, requires each and every one to be absolutely uniform and free of defects. As a result, this medical product’s multistage manufacturing process places high demands on the material, particularly in terms of its weldability and formability. Stainless precision steel strip from Waelzholz offers the perfect properties for this purpose.
“The production of fine medical cannulas from cold rolled steel strip requires several production steps with different requirements – the most crucial of which are forming and welding the material into tubes, as well as the subsequent drawing process, which reduces the cross-section by up to 80 percent,” explains Ralf Sauer, sales specialist for stainless precision steel strip at Waelzholz.
Our materials meet a wide range of requirements from customers in the medical technology sector:
- Stainless steel material
- Perfect weldability
- Excellent formability
- Flawless surfaces
- Consistently high quality over numerous production batches
