304 Stainless Steel Tube
304 stainless steel tube is the most widely used austenitic grade. It resists corrosion in air, fresh water, food and many chemicals, welds easily and deep-draws well. We supply it welded (EN 10296-2 / ASTM A269) or seamless (GOST 9941 / ASTM A213), in straight lengths or small-OD coil.
Price: quoted per specification. Stainless prices follow nickel and molybdenum, so each price is confirmed at the time of order.

304 vs 304L
304L has lower carbon, which reduces carbide precipitation at the weld and keeps corrosion resistance after welding. For welded tube we recommend 304L unless the part is not welded.
Compare 316 / 316L stainless steel tube for chloride and marine service.
