ASTM A519 Seamless carbon and alloy steel mechanical tubing
Dimension: O.D.:6-168mm W.T.:1-15mm L:max12000mm
Applications: for mechinery, mechanical engineer
Produce method:Cold drawn
Special Smoothness Inside Surface,SSIS
this tubing is intended for use where the inside surface is of
prime importance.
Usually we leave maching allowance for both OD and ID tolerance for
further maching purpose.
Mothod of tube forming:
1. Hot-Finished Mechanical Tubing
2. Cold-Worked Mechanical Tubing
3. Rough -Turned Mechanical Tubing
4. Ground Mechanical Tubing
Thermal Treatment:
1) A-Annealed
2) N-Normalized
3) QT-Quenched and Tempered
4) SR-Stress relieved or Finish Anneal
