Understanding ASTM A519 Grade 1040
ASTM A519 is a standard specification covering seamless carbon and alloy steel mechanical tubing. Among the various grades listed under this standard, Grade 1040 is a medium-carbon steel that offers a strong combination of mechanical strength and machinability.
ASTM A519 Grade 1040 tubes are supplied mainly in seamless form, making them suitable for applications that involve pressure, vibration, and repeated stress cycles. Because of this, AISI 1040 ASTM A519 carbon steel seamless tubes are commonly selected for precision-engineered components.
Manufacturing Process of ASTM A519 Gr 1040 Seamless Steel Tubing
As an ASME A519 Gr.1040 seamless hot-finished mechanical tubing manufacturer, we follow proven manufacturing practices that ensure consistency and performance.
Seamless Tube Production
High-quality carbon steel billets are heated and pierced to create hollow tubes without any welding seam. This ensures uniform strength throughout the tube.
Hot-Finished & Cold-Drawn Options
- Hot-finished tubes are ideal for heavy mechanical and structural use
- A519 Grade 1040 CD seamless tubes are preferred where tight tolerances and smooth surface finish are required
Heat Treatment
Depending on the end use, tubes can be heat treated to enhance strength, toughness, or machinability.
