Stainless Steel 302 Pipes & Tubes (UNS S30200) offer the classic 18-8 austenitic stainless profile with a slightly higher carbon content than 304. This makes them a practical option where good strength, formability and general corrosion resistance are required, especially in light-to-medium duty service, decorative piping, instrumentation lines and fabricated tube assemblies.

Applications of Stainless Steel 302 Pipes & Tubes
SS 302 Pipes & Tubes are chosen for good forming behavior and general corrosion resistance. Here are the typical application of Stainless steel 302 tubes and Stainless steel 302 pipes:
- Food & beverage utilities, wash lines, guards, rails, and tubing accessories: Used for non-pressure utility runs, spray bars, drip lines, machine guards, and handrails in washdown zones. Cleanability and polish options suit hygienic areas, and easy forming helps with bends and custom fittings.
- Springs, clamps, and fastener components integrated with tube assemblies: 302’s work-hardening supports spring clips, saddle clamps, banding, and quick-release hardware on tube frames. Parts can be stamped and cold-formed to high strength; qualify any welding near formed areas to protect performance.
- General engineering, automotive brackets, supports, and conduits: Suitable for conduits, guides, sensor stands, brackets, and trim tubing that need neat bends and a clean finish. Provides reliable corrosion resistance for indoor or mild outdoor service; use 316 where chlorides or road salts are present.
FAQ’s about Stainless Steel 302 Pipes & Tubes
What is the difference between 302 and 304 for pipes and tubes?
Both are 18-8 austenitic grades. 302 has slightly higher carbon than 304, which can give higher strength after cold work but a greater tendency to carbide precipitation in the heat-affected zone. For weld-heavy service, many buyers prefer 304L.
Can SS 302 be welded for pressure pipework?
Yes, but select procedures and filler carefully. Common filler choices include ER308 or ER312. If intergranular corrosion is a concern, post-weld heat treatment or choosing a low-carbon grade like 304L may be advisable. Always qualify procedures to the job standard.
Which standards cover Stainless Steel 302 Pipes & Stainless Steel 302 Tubes?
Suppliers commonly offer SS 302 against ASTM A312 (pipes) and A213/A269/A249 (tubes). Confirm TP302 availability with the mill or stockist because coverage varies by producer and region.
Is 302 magnetic?
In the annealed state it is essentially non-magnetic. Cold work increases strength and can make it slightly magnetic.
What affects the price of SS 302 Pipes & Tubes?
Price depends on outer diameter and wall thickness, schedules, seamless vs welded route, finish, testing, and order quantity. Market nickel surcharges also move the final price. Many suppliers quote 302 alongside 304/316 with separate ranges per route.
What documentation do you provide as a Manufacturer, Supplier and Exporter?
Standard pack includes EN 10204 3.1 MTC with heat chemistry and mechanicals, dimensional reports, and NDT as ordered. Export packing lists and country-of-origin certificates are issued on request.
