The document discusses Fine Tubes' production of medical-grade stainless steel and titanium alloy tubing. It provides details on: 1) Their size range of 0.3mm to 50.8mm outer diameter tubing that can achieve tolerances of 0.0127mm. 2) Their quality control process which controls parameters like surface finish, inclusion levels, and grain size to stringent levels. 3) The advantages of their tubing including refined inner surface finish, low defect levels, and tight tolerances.

The demand for high performance stainless steel and titanium alloys that can offer excellent strength-to-weight
medical
ratios is constantly increasing. This in combination with high levels of microbiological corrosion resistance and fatigue
life properties is the challenge which has been exceeded by our tubular medical pre-materials.
Our high levels of ID and OD surface finish, tolerance and ovality controls yield a product which is cost competitive
against the existing gun drilled technology. At the same time it can offer the further benefits of consistency and
typically 10ft (3m) lengths.
Applications
Size Range
Our size range for medical products is based upon manufacture of cold drawn tubing from 0.30 mm (0.012") to
50.8mm (2") OD. Tolerances: OD and ID up to 0.0127mm (0.0005") are achievable.

The process for quality control within Fine Tubes is critical in respect of consistently achieving the highest level of
specification requirements.
Reduction control through pilgering and drawing is specific to each product dimension and specification
requirements. This is the driver for tolerance control, OD and ID surface finish control, inclusion levels and final
grain size.
ID surface finish is further refined by passivation, polishing or electropolishing processes.
OD surfaces are finished down to 0.1μm (0.25μ"), ID down to 0.2μm (0.5μ").
Grain size is based upon ASTM E112. Our process control enables grain size control to obtain levels ≥8.
Typical Manufacturing Standards
● ASTM F2063-00 - NiTi Shape Memory Alloy ● 21Cr 10Ni 3Mn 2.5 Mo
● ASTM F136 1996 Ti6/4 ELI ● ISO 5832-11 1994 BS7252: Part 11 - Ti 6Al 7Nb
● ASTM F138-00 316L/316LVM ● ISO 5832-9 1993 BS7252: Part 9

Tube Advantages
ID Surface Finish: Refineed by centreless grinding and/or ID electropolishing to acheive 0.2 μm (0.5 μ”).
ID Defect Levels: UT tested to levels down to 20 microns (0.02mm/ 0.0008”).
Fatigue life: Control of texture combined with extra low levels of interstitual impurities leads to higher fatigue
performance than equivalent drilled bars.
Tolerances: In-house control to ISO 286-2 h8.
