Published: November 12, 2025 | Updated: November 12, 2025By Gangsteel Engineering Team – 25+ Years in Stainless Steel Export Excellence

In the specialized domain of stainless steels compliant with ASME SA-479/SA-479M – Type 316Ti and ASTM A479/A479M – Type 316Ti standards, 316Ti bar is a titanium-stabilized austenitic material engineered for superior performance in high-temperature, corrosive, and pressure-containing applications requiring precision machining and durability.

As a premier producer and exporter based in China, Gangsteel has supplied thousands of tons of 316Ti bar, fully compliant with ASME SA-479/SA-479M – Type 316Ti and ASTM A479/A479M – Type 316Ti, to industries like petrochemical, marine, and manufacturing.

If you're sourcing 316Ti bar under ASME SA-479/SA-479M – Type 316Ti 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 bar specifications, properties, and stock availability, based on ASME SA-479/SA-479M – Type 316Ti and ASTM A479/A479M – Type 316Ti standards.

From our production lines, 316Ti bar specs shine: In a 2024 Los Angeles valve manufacturing project, our 316Ti bars under ASME SA-479/SA-479M – Type 316Ti 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 bar's density of 8.00 g/cm³ supports lightweight yet robust designs. Let's explore 316Ti bar — from composition to stock — for your next project.
