Small Diameter Tubes, Stainless Steel 304, are precision-made for use in applications that call for superior corrosion resistance, high strength and dimensional accuracy. They have a high chromium and nickel content of about 18-20% and 8-10.5% respectively and are made of SS 304 (UNS S30400) which offers exceptional resistance to oxidation, good formability and excellent weldability. Can be supplied seamless and welded, and cold worked to increase tensile strength without compromising performance in severe service conditions. They are smooth and have tight tolerances, which can be used in precision fluid transfer and instrumentation systems. The low carbon 304L is also offered to promote weldability and corrosion resistance after welding. USA Piping Solution is a reliable, trusted, and quality small diameter stainless steel tubes manufacturer and supplier that offers tubes with custom sizes and reliable performance to meet various industrial needs and requirements.

Frequently Asked Questions
What are Stainless Steel 304 Small Diameter Tubes?
Stainless Steel 304 Small Diameter Tubes are precision tubes with small outside diameters, offering good corrosion resistance, strength, and excellent formability for compact industrial systems.
What is considered a small diameter stainless steel tube?
A small diameter stainless steel tube typically has an outside diameter of less than 25.4 mm (1 inch) and is used where space is limited or precise fluid flow is required.
What is the difference between SS 304 small diameter tubes and SS 316 small diameter tubes?
SS 304 tubes are suitable for general corrosion-resistant applications, while SS 316 tubes contain molybdenum, providing better resistance to chlorides, chemicals, and marine environments.
What is the smallest diameter available in SS 304 tubing?
Depending on the manufacturer, SS 304 tubing can be produced with outside diameters as small as 0.2 mm to 0.3 mm for precision applications.
Can SS 304 Small Diameter Tubes be used for food and pharmaceutical applications?
Yes. SS 304 Small Diameter Tubes are widely used in food processing and pharmaceutical equipment because of their corrosion resistance, hygienic surface, and ease of cleaning.
