What is ASTM A519 Seamless  Steel Tube?

ASTM A519 is the standard specification for seamless carbon and alloy steel mechanical tubing. Hot-finished or cold-drawn processes manufacture these tubes and are primarily intended for mechanical engineering applications, rather than pressure piping. However, due to their robustness and reliability, they are also used in structural and industrial applications.

Key Features of ASTM A519 Tubes

  • Manufactured in both hot-finished and cold-drawn conditions

  • High dimensional accuracy and smooth surface finish

  • Available in a wide range of OD (Outside Diameter) and Wall Thickness

  • Excellent machinability and weldability

  • Superior resistance to stress, pressure, and load-bearing conditions

Available Grades of ASTM A519 Tubes

Low-Carbon MT Grades

These grades are designed for general mechanical applications, offering good machinability and formability.

  • MT 1015

  • MT X1015

  • MT 1020

  • MT X1020

Carbon Steels

Standard carbon steel grades with varying carbon content, providing different levels of hardness, weldability, and strength.

  • 1018, 1020, 1025, 1026

  • 1035, 1045, 1050

Alloy Steels

These grades include alloying elements such as chromium and molybdenum, giving excellent strength, toughness, and heat resistance.

  • 1330, 1335, 1340

  • 4130 (Chromoly)

  • 4140 (Chromoly)

Resulfurized Carbon Steels

Grades with higher sulfur content, enhancing machinability while retaining adequate strength.

  • 1118, 1137
