Bright Annealed ASTM A269 / A213 TP316 TP316L Stainless Steel Seamless Tube For Industry , ET HT
ASTM A269/A213 TP316/316L Bright Annealed Stainless Steel Seamless Tube is a dual-specification, dual-grade, seamless austenitic stainless steel tube supplied in the bright annealed (BA) condition. Each tube meets the chemical, mechanical, test and dimensional requirements of both standards, and the heat lot is qualified for both TP316 and TP316L(low carbon variant). It is normally cold-drawn / cold-finished seamless, then processed under bright annealed (BA) condition inside a controlled inert atmosphere furnace, producing a clean, oxide-free, lustrous metallic surface without pickling scale. YUHONG GROUP specializes in producing stainless steel seamless tubes for more than 35 years. We can provide different surface finish of ASTM A269/A213 stainless steel tubes, such as bright annealed, pickled and annealed, mechanical polished, and so on.
