Frequently Asked Questions
What are Stainless Steel 304 Small Diameter Tubes?
SS 304 Small Diameter Tubes are precision tubes with a small outside diameter, designed for applications requiring accurate dimensions, tight tolerances, and reliable fluid or gas transfer.
What is the minimum diameter of SS 304 Small Diameter Tubes?
SS 304 Small Diameter Tubes can be manufactured from 0.007 inches OD (approximately 0.18 mm), depending on the manufacturing process, wall thickness, and customer requirements. The available OD range is 0.007 inches to 1.25 inches.
What is the difference between SS 304 and SS 304L Small Diameter Tubes?
SS 304L has a lower carbon content than SS 304, providing better resistance to sensitization after welding. SS 304 generally offers slightly higher strength.
Are SS 304 Small Diameter Tubes corrosion resistant?
Yes. SS 304 provides good corrosion resistance against moisture, atmospheric conditions, and many mild chemicals.
Can SS 304 Small Diameter Tubes be welded?
Yes. SS 304 Small Diameter Tubes have good weldability and can be welded using suitable processes while maintaining proper heat control.
