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 non-toxic and safe nature is a key attribute for applications in food processing, medical devices, and pharmaceutical equipment, where material inertness and biocompatibility are paramount.
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 assessing if 316Ti is non-toxic and safe under ASME SA240/SA240M for food contact, implants, or sanitary piping where leaching, toxicity, and biocompatibility are critical, understanding its properties is essential. This article explores if 316Ti is non-toxic and safe, with data on leachability, biocompatibility, and insights, based on ASTM A240/A240M and ASME SA240/SA240M standards and our mill tests.
From our production lines, we've confirmed 316Ti's non-toxic safe profile: In a 2024 U.S. pharmaceutical tank project, our 316Ti plates under ASTM A240 /A240M showed zero leaching of heavy metals in USP <661> tests at 121°C sterilization, ensuring FDA compliance for non-toxic safe use, as per client lab reports. Compliant with ASME SA240/SA240M for pressure apps, 316Ti's density of 8.00 g/cm³ supports hygienic designs. Let's delve into the non-toxic safe aspects, from composition to test data, to guide your selection.
316Ti stainless steel is non-toxic and safe for food contact, medical, and pharmaceutical use, with no harmful leaching under normal conditions (USP <661> pass, FDA 21 CFR compliant), thanks to its stable passive layer and low migration rates (<0.01 mg/dm² in acids). Density 8.00 g/cm³, PREN 23-28. Ti stabilization ensures biocompatibility (ISO 10993 pass for implants). Superior to 304 in acids; ideal for cookware. Gangsteel stocks 1-200mm with certs for custom needs.
The chemical composition of 316Ti, as per ASTM A240/A240M and ASME SA240/SA240M, is optimized for non-toxic safe use, with low impurities and stable alloys preventing leaching.
