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 1.8mm thickness stock is optimized for thin-sheet applications requiring high-temperature stability and corrosion resistance.
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 sourcing 1.8mm thickness stock under ASME SA240/SA240M for lightweight components or welded structures where thin gauge is key, understanding availability, specs, and properties is essential. This article explores 316Ti 1.8mm stock, properties, and insights, based on ASTM A240/A240M and ASME SA240/SA240M standards and our mill data.
From our production lines, we've seen 1.8mm 316Ti stock in action: In a 2024 U.S. electronics prototype, our 1.8mm sheets under ASTM A240 /A240M provided superior IGC resistance at 200°C post-weld, enabling compact designs without failure, as per client thermal tests. Compliant with ASME SA240/SA240M for pressure apps, 316Ti's density of 8.00 g/cm³ supports thin-stock efficiency. Let's delve into the details, from composition to stock options, to guide your sourcing.
316Ti stainless steel 1.8mm thickness stock under ASTM A240/A240M and ASME SA240/SA240M offers tensile 515 MPa min, yield 205 MPa min, elongation 40% min, and hardness 95 HRB max, with Ti for IGC resistance at 425-815°C. Ideal for thin chemical linings or marine panels; density 8.00 g/cm³, PREN 23-28. Equivalent to EN 1.4571; thinner stock (1.8mm) at $3,500-4,000/ton FOB. Gangsteel stocks 1.8mm sheets with certs for custom needs.
The chemical composition of 316Ti, as specified in ASTM A240/A240M and ASME SA240/SA240M, is optimized for thin 1.8mm stock properties, with titanium ensuring stability.
