Stainless Steel Seamless Tube to GOST 9941
Seamless cold drawn stainless steel tube to GOST 9941 in Russian grades 08Х18Н10Т and 12Х18Н10Т (AISI 321), 10Х17Н13М2Т (AISI 316Ti) and AISI 316L. The tube is drawn to a tight tolerance with a clean, uniform surface, ready for machining, instrumentation and corrosive-service lines. Russian-language documents and mill test certificates are standard on every lot.
Price: quoted per specification. Stainless surcharges move with nickel and molybdenum, so each quotation is confirmed at the time of order.
