SS 304 seamless tubes are a type of austenitic stainless steel tube that is manufactured without welding. Being seamless, these tubes offer uniform mechanical properties, excellent strength, and resistance to corrosion.
The composition of SS 304 includes chromium (18-20%) and nickel (8-10.5%), providing resistance to oxidation and corrosion in a variety of environments. Unlike welded tubes, seamless tubes do not have a seam, eliminating weak points and enhancing performance under high pressure or high temperature.
Applications include pipelines, heat exchangers, condensers, chemical reactors, pharmaceutical equipment, and food processing systems. Their versatility and long service life make them a vital component in industries requiring durable and reliable tubing solutions.
