Stainless Steel Seamless Tube
Stainless steel seamless tube has no longitudinal weld, which gives a uniform wall and reliable behaviour under pressure and temperature. We cold draw to GOST 9941-2022, ASTM A213 / A269 and EN 10216-5 in austenitic grades 304 / 304L, 316 / 316L, 316Ti and 321.
Price: quoted per specification. Seamless costs more than welded; we quote both so you can choose the right balance.
