Type 304/304L stainless steel, with its chromium-nickel content, is the most versatile and widely used of the austenitic stainless steels. No other grades of stainless steel come in so many forms and finishes or is used with such diverse applications. These grades can be severely deep drawn without intermediate annealing, which has made these grades the industry standard in the manufacture of drawn stainless parts. The lower carbon content in 304L grade increases resistance to intergranular corrosion following welding or stress relieving. These grades of stainless steel are the most economical and readily available.
*304L 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.
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.
