SEAMLESS BRIGHT ANNEALED TUBE ASTM A213 / ASTM A269 COLD ROLLING

BA (Bright annealed), is a specific surface finish which is produces by the mills for cold-rolled stainless steels.During its production, the stainless steel is annealed in an inert gas atmosphere after cold rolling.

Characteristic: With cold press (mainly cold rolling), the gas protects heat treatment, with high precision:

ID:Ra≤0.4μm,OD:Ra≤0.8μm；Mainly for precision instrument, Hydraulic pressure system, exhaust gas

system etc.

Standard: ASTM/ASME A/SA213, A/SA269, DIN17458/17457, EN10216-5/10217-7. After negotiation, we can

supply pipe with customers’ requirement.

Material Grade: TP304, TP304L, TP316, TP316L, TP316Ti, and TP321 etc also DIN/EN grades available,

other grade can also be provided after consulting with customers.

Size Range:Seamless Tube(OD: Φ6mm-Φ76mm WT: 0.15mm-4.0mm, Length:Max. 500M/pc)

Supplementary Testing : Apart from the above mentioned tests, we also carry out on the manufactured products supplementary testing. The tests conducted under this include:

Application:
Bright annealed stainless steel welded pipe is widely used in making military products, semiconductor, biological medicine, precision instruments and meters, hydraulic parts and many other industrial products.
