In the specialized domain of stainless steels compliant with ASTM A240/A240M and ASME SA240/SA240M standards, 316Ti emerges as a titanium-stabilized austenitic grade whose chemical resistance is pivotal for applications in aggressive environments.
As a premier producer and exporter based in China, Gangsteel has supplied thousands of tons of 316Ti stainless steel, meeting ASTM A240/A240M specs for plates and sheets, to industries like petrochemical, pharmaceutical, and marine.
If you're seeking a chemical resistance chart in PDF format under ASME SA240/SA240M where compatibility with acids, bases, and solvents is critical, this article provides a detailed overview and downloadable insights. We'll explore 316Ti's resistance data, influenced by its unique composition, based on ASTM A240/A240M and ASME SA240/SA240M standards and our mill tests.
From our production lines, we've documented 316Ti's resistance: In a 2024 U.S. chemical plant, our 316Ti components under ASTM A240 /A240M showed excellent compatibility with dilute acids at 80°C, with rates <0.1 mm/year, as per client lab reports. Compliant with ASME SA240/SA240M for pressure apps, 316Ti's density of 8.00 g/cm³ supports stable performance. Let's delve into the chart, from composition to resistance data, with PDF download options, to equip you for informed selections.
316Ti stainless steel, compliant with ASTM A240/A240M and ASME SA240/SA240M, offers excellent chemical resistance with ratings like A (Excellent) for acetic acid and B (Good) for concentrated sulfuric, thanks to Ti stabilization preventing IGC. PREN 23-28 ensures strong pitting resistance in chlorides. Density 8.00 g/cm³, tensile 515 MPa min. Superior to 304 in acids/heat; similar to 316L but better high-temp. Download the PDF chart below for full data; Gangsteel stocks 1-200mm with certs.
The chemical composition of 316Ti, as specified in ASTM A240/A240M and ASME SA240/SA240M, is optimized for chemical resistance, with titanium ensuring stability in corrosives.
