Stainless Steel Tube Available Grades
Stainless Steel Tubes are available in many grades to suit different temperature, pressure and corrosion requirements. Used across industrial, structural and process piping applications. The following are the SS tube grades provided by Sachiya Steel.
Stainless Steel 304 Tubes
Most common grade.
Works for general industrial and commercial use where the main needs are easy
fabrication and resists corrosion well.
Stainless Steel 304H Tubes
Higher carbon version
of 304, designed for elevated temperature service. Minimum carbon content of 0.04% gives
it better creep resistance at high temperatures.
Stainless Steel 316 Tubes
Similar to 304 but
with molybdenum added. Holds up better in chloride and chemical exposure. Used where 304
tends to fall short.
Stainless Steel 316Ti Tubes
316 grade with
titanium stabilisation. Handles thermal exposure better and reduces weld sensitisation
risk. Used in high-temperature process environments.
Stainless Steel 321H Tubes
High carbon version
of 321. Performs well under sustained high heat. Common in furnace components, thermal
processing, and aerospace applications.
Stainless Steel 904L Tubes
High-alloy grade.
Strong resistance to sulfuric acid and chloride-heavy environments. Used mainly in
aggressive chemical processing conditions.
Types of Stainless Steel Tube
Stainless steel tubes come in several types, depending on how they are made and what shape they are. The right type is chosen based on the needed strength, surface finish, and application requirements.
Welded (ERW) Tube
Seamless Tube
Polished Tube
Stainless Steel Round Tube
Stainless Steel Square Tube
Stainless Steel Rectangular Tube
Stainless Steel Tube Price
Stainless steel tube in India, prices are about ₹180 to ₹425 per kg. In the US, prices run from about $3 to $4 per kg. Prices depend on shape, size, grade, wall thickness, finish and order quantity. Grade 304 stainless steel tube is usually 15 to 20% lesser than grade 316. Seamless tubes cost more than welded tubes. Full 20 ft lengths offer the lowest price per foot.

Industrial Applications of Stainless Steel Tube
Stainless steel tubes serve 4 primary application areas that demand corrosion resistance, structural integrity and hygienic surfaces.
Heat Exchangers & Fluid Transfer
Seamless stainless steel tube per ASTM A213 is the standard for shell-and-tube heat exchangers and condensers. Grade 316 is specified where chloride exposure presents a corrosion risk.
Architectural & Structural
Welded SS square tube and stainless steel rectangular tube are common in handrails, balustrades, and structural framing.
Food Processing & Marine
Grade 316L stainless steel tubing is preferred for dairy equipment, pharmaceutical lines, and marine structures. It's 2.00-3.00% molybdenum content resists pitting from salt water and cleaning agents.
Industrial & Fabrication
Grade 304 SS tube provides a practical balance of corrosion resistance, formability, and cost for exhaust systems, instrumentation, and furniture manufacturing. Grade 321 is specified for continuous service above 500°C.
