Applications & Selection Guide
Welded round tube in AISI 304 (1.4301) to DIN 11850 and EN 10217-7, sized by outside diameter × wall. 304 is the general-purpose austenitic stainless grade: corrosion resistant in normal indoor and outdoor atmospheres, easy to weld and to bend.
It is used for handrails and balustrades, food and beverage lines, furniture, kitchen equipment, frames and general fabrication. Outside diameters run from Ø14 mm to Ø219.1 mm with walls of 1–4 mm by size.
Stock lengths are commonly 2, 3 and 6 m, with 1 m on some sizes. Send size, wall, length, quantity and destination in a quote request; we confirm stock, price and lead time.
