Component Supply offers a wide selection of 304 stainless steel medical device mandrels, catheter mandrels, and guidewires engineered for catheter development, minimally invasive devices, and medical device R&D.
Our 304 stainless steel wire is spring-tempered, drawn, and straightened with a bright finish, providing consistent chemistry with minimal voids and contaminants. Strong, flexible, and corrosion-resistant, it’s ideal for non-implantable medical devices and supports prototyping and production-scale projects.
All sizes 0.040″ and below carry the V designation, while larger diameters may not carry the V designation.
All wires and mandrels ship in straight lengths, without end forms, with standard lengths of 36″ or 72″. For custom lengths, grinding or end-form fabrication, please complete our Quote Form.

Component Supply wires and mandrels provided as a resource for research and development purposes in a variety of markets.
Medical markets include:
Other markets include:
Potential end-uses include:
Hypodermic tubing is commonly used in catheter assemblies where torque response, pushability, and wall thickness optimization are critical. Thin wall and ultra thin wall tubing can help maximize internal lumen size while maintaining profile constraints.
Stainless steel mandrels are used for support, shaping, forming, and assembly processes in medical device manufacturing. Tight diameter tolerances and surface finish consistency are often critical.
Stylets may utilize stainless hypotube for column strength, steerability, and dimensional consistency in minimally invasive devices.
Guidewire assemblies may incorporate hypotube sections for stiffness transitions, torque transmission, and proximal support.
Introducer systems often rely on precision tubing dimensions and burr-free cut lengths to support smooth assembly integration and device performance.
Hypotubes used in push-pull rod assemblies may require optimized stiffness, tight tolerances, and secondary fabrication such as grinding or drilling.
Hypodermic tubing may be incorporated into guidewire assemblies requiring transitions between flexibility and support.
CS Custom Fab, the fabrication division of Component Supply, provides precision secondary operations for 304V stainless steel medical wire and custom mandrels. Working from customer drawings and specifications, our experienced team manufactures components to meet the tight tolerances and demanding quality standards required for medical device development, prototyping, and production.
Our custom fabrication services include:
Whether you’re developing a new catheter, guidewire, delivery system, or another precision medical device, CS Custom Fab supports every stage of development with low order minimums and responsive manufacturing. Standard shop minimums typically begin at $300, making it easier to prototype, validate designs, and move toward production without committing to high-volume orders.
