In the demanding arena of stainless steels compliant with ASTM A240/A240M, ASME SA240/SA240M, EN 10088-2/EN 10095 (1.4571), GB/T 24511 (06Cr17Ni12Mo2Ti), and JIS G4303 (SUS316Ti), 316Ti emerges as a titanium-stabilized austenitic grade whose bolt and fastener stock is optimized for high-temperature and corrosive environments requiring secure, durable connections.
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, marine, and manufacturing.
If you're sourcing 316Ti bolt and fastener stock under ASME SA240/SA240M for components like valve assemblies or structural joints where strength, corrosion resistance, and compliance are critical, understanding its specifications and availability is essential. This article explores 316Ti bolt and fastener stock, properties, and insights, based on ASTM A240/A240M, ASME SA240/SA240M, EN 10088-2/EN 10095 (1.4571), GB/T 24511 (06Cr17Ni12Mo2Ti), and JIS G4303 (SUS316Ti) standards and our mill data.
From our production lines, we've seen 316Ti bolt and fastener stock in action: In a 2024 U.S. offshore platform project, our 316Ti bolts under ASTM A240 /A240M and ASME SA240/SA240M standards, equivalent to EN 10088-2/EN 10095 (1.4571), GB/T 24511 (06Cr17Ni12Mo2Ti), and JIS G4303 (SUS316Ti), withstood 500°C H2S exposure without loosening, enhancing safety and longevity as per client torque tests. Compliant with ASME SA240/SA240M for pressure apps, 316Ti's density of 8.00 g/cm³ supports lightweight yet strong fasteners. Let's delve into the stock details, from composition to sourcing, to guide your procurement.
