UTS of 316L hypodermic needles

[gyroscpe]

I'm trying ot specify a required minimum UTS for 316L full hard hypodermic needles. I'm working specifically with 15RW and smaller. An ASTM number would help.

How about ISO?

ISO 9626 Stainless steel needle tubing for the manufacture of medical devices

Please see FAQ731-376 for tips on how to make the best use of Eng-Tips Fora.

Thanks. I'll have look. I found ASTM A908-03 but was not sure if it applied to 316L also. I did not see the molybdenum in the chem requirement.

Vita Needle states that their hypodermic tubing is full hard giving a 150 ksi min tensile. I have another reference that states the same thing hypodermic tubing, but gives no values.

If you look at 316 wire it will give a little higher values, 185 ksi min TS for full hard.

ASTM A666 give the cold worked properties of SS.
