ASTM A519 Seamless Carbon and Alloy Steel Mechanical Tubing

Product Description

A519 Seamless Steel Pipe

ASTM A519 (identical to ASME SA-519) is the standard specification for seamless carbon and alloy steel mechanical tubing. Unlike pressure pipe standards (such as ASTM A106 or A335), ASTM A519 is specifically designed for mechanical applications where precise dimensions, consistent machinability, and reliable mechanical properties are essential.

The standard covers both hot-finished and cold-finished seamless tubing in a wide range of carbon and alloy steel grades. It is widely recognized in industries such as automotive manufacturing, hydraulic systems, precision machinery, and aerospace components .

Current Standard: ASTM A519/A519M-24a (2024 Edition)
