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 renowned for its balanced material properties, making it ideal for corrosive and high-temperature 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 evaluating 316Ti for a welded tank or exhaust system under ASME SA240/SA240M where properties like strength, corrosion resistance, and thermal stability are critical, this overview provides comprehensive data. We'll explore its key material properties, 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 observed 316Ti's property excellence: In a 2024 U.S. chemical facility, our 316Ti components under ASTM A240 /A240M exhibited superior IGC resistance at 600°C, maintaining properties for extended service, as per client evaluations. Compliant with ASME SA240/SA240M for pressure apps, 316Ti's density of 8.00 g/cm³ supports efficient designs. Let's delve into the overview, from composition to applications, to equip you for informed selections.
316Ti stainless steel, compliant with ASTM A240/A240M and ASME SA240/SA240M, offers tensile strength 515 MPa min, yield 205 MPa min, elongation 40% min, hardness 95 HRB max, and thermal conductivity 14.6 W/m·K, with Ti stabilization preventing IGC at 425-815°C. Density 8.00 g/cm³, PREN 23-28 for pitting resistance. Superior to 316 in high-temp durability, it's weldable and formable. Ideal for chemical reactors and marine; Gangsteel stocks 1-200mm with certs.
The chemical composition of 316Ti, as specified in ASTM A240/A240M and ASME SA240/SA240M, is optimized for material properties, with titanium ensuring stability against carbide formation.
