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.
