Description
ASTM A519 Seamless Carbon Steel Alloy Mechanical Tubing
ASTM A519 specified several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished.
Alloy grade: ASTM A519 4012,4042,4130,4140,4142
Size range:Hot-rolled: O.D: 51-508mm; W.T:7∼60mm; L: max 16000mm
Cold-drawn: O.D: 10-50; W.T:2∼10; L: max 16000
Method 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
