In the precision domain of stainless steels compliant with ASTM A276 – Type 316Ti and ASTM A479/A479M – Type 316Ti, 316Ti round bar stands as a titanium-stabilized austenitic material engineered for superior performance in high-temperature, corrosive, and machined applications requiring dimensional accuracy and durability.
As a premier producer and exporter based in China, Gangsteel has supplied thousands of tons of 316Ti round bar, fully compliant with ASTM A276 and ASTM A479/A479M, to industries like petrochemical, marine, and manufacturing.
If you're sourcing 316Ti round bar for valve stems, shafts, or fasteners where strength, corrosion resistance, and machinability are critical, Gangsteel delivers mill-direct stock with full traceability. This article covers 316Ti round bar specifications, properties, and stock availability under ASTM A276 and ASTM A479/A479M.
From our production lines: In a 2024 Los Angeles valve manufacturing project, our 316Ti round bar under ASTM A240 /A240M (complementary to A276) achieved HRC 25 hardness after machining, ensuring tight tolerances for M20 stems without IGC in sour service. With ASME SA240/SA240M approval for related components, 316Ti round bar's density of 8.00 g/cm³ supports lightweight yet robust designs. Let’s explore 316Ti round bar — from composition to stock — for your next project.
