ASTM A269 Stainless Steel Seamless Tube For Aerospace / Mechanical Structure





Cold drawn or cold-rolled precision seamless steel tube (GB3639-2000) is used for precision mechanical structure, hydraulic equipment and high surface finish of cold drawn or cold-rolled precision seamless steel tubes.


Pipe Ends: Beveled or plain

Surface: Acid wash and Annealing

Packing Woven bags About 2ton for each bundle
Dimension OD Size 1/8 - 32 inch

XS STD sch5 sch10 sch20 sch30

sch40 sch80 sch160

Length 5 - 5.8m, 6m,double random length





In order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing method must be used or combined. Cold usually in two roller mill, rolling ring groove tapered plug pipe in variable cross section circular slot and the composition of the. Cold drawing was usually in the 0.5 ~ 100T single chain or double chain drawbench.
