Type 316/316L stainless steel, with its chromium-nickel and low carbon content, is a commonly used austenitic stainless steel. This alloy has similar physical properties and fabrication characteristics as Type 304. The addition of molybdenum (versus 304) increases the corrosion resistance in saltwater applications. The biocompatibility of this alloy has been well researched. This grade of stainless is an economical option and typically readily available. The lower carbon content in 316L grade increases resistance to intergranular corrosion following welding or stress relieving.
*316L has a lower carbon content of 0.03% max

Additional tubing specification information can be found in K001-15a Standard Specification for Miniature Laser Welded and Drawn Stainless Steel and Nickel-Chromium Alloy Tubing for General Use on the K-Tube’s website at bit.ly/stainlesssteeltubing
K-Tube has the capability to make tubing with the wall thickness and outside diameter combinations in the table below. Tubing with an OD/Wall ratio lower than 20:1 can be drawn to the final dimensions. Tubing with an OD/Wall ratio between 20:1 and 40:1 must be centerless ground to the final dimensions. K-Tube's capabilities are constantly improving, please inquire if your dimensions are outside of the listed dimensions.
