Medical Stainless Steel Tubing - Small Diameter
Most standard small diameter medical stainless steel tubing falls into a range of 3/8" OD or less. Navigating to the hypodermic, fractional or metric charts or the master chart (a combination of all 3 charts) using the links on the left hand side of the page will give you lists of standard welded and drawn stock sizes that Vita Needle carries. |
 |
| Below you will find a brief comparison of the two processes. Please click on "welded and drawn ss tubing" or "seamless stainless tubing" links to learn more about the capabilities of each process. Or you can call us for guidance---we have hundreds of years of combined experience working with tubing and we routinely run custom tubing to specifications for customers. | |
| *Faster lead times *High quality using modern methods *Can hold closer tolerances *Better concentricity *Usually more economical than seamless |
*Ideal for very heavy walls *Preferred for some specialty application needs *Typically longer lead times and higher minimums *No welding, fabricated from forged hollow bar *Historical favorite of many engineers |
ALLOY SELECTIONS |
|
| 304 / 304 L: The most common 300 stainless series alloy, good corrosion resistance, cold working characteristics and relative cost effectiveness make this our most popular alloy. | 316 / 316 L: The addition of molybdenum to the base metal improves corrosion resistance for use in medical / food service and other demanding tubing applications. |
| 17-7: The addition of aluminum in this alloy provides improved tube strength and hardness while maintaining good corrosion resistance. | Alloy 52 and 600: Often used for specialty applications requiring corrosion resistance at high temperatures, these alloys have a much higher nickel content compared to stainless steel. |
| 302: Very similar corrosion resistance to stainless 304, but higher strength due to carbon content. Typically not available in tubing, wire/solid only. | 303: An ideal stainless steel alloy for machining parts due to the addition of elements which reduce tool wear / expense. Available for machined parts only, not offered as tubing. |
| 321: Increased strength and corrosion resistance, especially at higher temperatures are characteristics of this alloy due to the addition of titanium to the base metal. | 347: Characteristics are similar to 321, but the addition of several alloys allows tubing to withstand high temperatures for longer periods. |
| Other Alloys: We also work with a variety of tubing in non-stainless alloys such as brass 260, various copper alloys and aluminum. If you've got a special tubing requirement, give us a call. | |
