Sheets in steel grade 1.4571/316Ti

Sheets in steel grade 1.4571 (commonly known as 316Ti) are titanium‑stabilised austenitic stainless steel sheets offered for applications that require good general corrosion resistance together with enhanced stability at elevated temperatures. This grade is widely used where welding or heat exposure could otherwise cause sensitisation (grain‑boundary carbide precipitation) in standard 316 grades.

What is 1.4571 / 316Ti?

1.4571 is the European EN designation for the stainless steel grade more frequently referred to as 316Ti (US/ASTM reference: AISI 316Ti / UNS S31635). It has the same basic alloying balance as 316 (chromium, nickel and molybdenum) but contains titanium as a stabiliser. The titanium ties up carbon and reduces the risk of intergranular corrosion after exposure to temperatures common in welding or some high‑temperature services. In plain terms: it behaves like 316 in many corrosive environments but withstands certain heat exposures better.

Key properties and advantages

• Corrosion resistance: Good resistance to a wide range of corrosive media typical for 300‑series stainless steels (chloride-containing environments, many chemical processes, food environments).
• High‑temperature stability: Titanium stabilisation reduces sensitisation, making 316Ti suitable for components exposed to elevated temperatures during fabrication or in service.
• Weldability and formability: Like other austenitic grades, 316Ti is readily weldable and cold‑formable. Post‑weld cleaning and passivation are recommended for maximum corrosion performance.
• Versatility: Available in a variety of surface finishes used for industrial, architectural and sanitary applications.

Where and how 316Ti sheets are used

Sheets in 1.4571/316Ti are used across a broad range of sectors — from small workshop and garage projects to heavy industry. Typical applications include:

• Chemical and petrochemical plant equipment (linings, tanks, piping components where intermittent high temperatures occur)
• Heat exchangers, boilers and furnace components exposed to elevated temperatures
• Offshore and marine components where chloride resistance is needed alongside thermal stability
• Food processing and beverage equipment where corrosion resistance and cleanable surfaces are required
• Architectural cladding, façades and decorative panels that may be welded on site
• Automotive exhaust components and industrial ducting
• Pressure vessels and welded constructions where post‑weld stability is desirable

Who buys 1.4571 / 316Ti sheets?

• Fabricators and welders needing sheets that tolerate welding cycles without loss of corrosion resistance
• Engineers and procurement teams in chemical, offshore, food and pharmaceutical industries
• Architects and contractors specifying durable cladding and sanitary surfaces
• Hobbyists and small businesses requiring cut‑to‑size corrosion‑resistant sheet for bespoke projects

Selecting the right sheet: finishes, thickness and certification

When choosing 316Ti sheets consider:

• Surface finish: common finishes include cold‑rolled (2B), brushed (No.4) and mirror (BA) — select depending on aesthetic and cleaning needs.
• Thickness: choose according to mechanical requirements and forming/welding methods; thinner gauges are easier to form, thicker gauges give greater stiffness and wear resistance.
• Edge and cut options: specify sheared, mill‑trimmed or laser/plasma cut edges when ordering processed sheets.
• Certification: for critical or regulated applications request mill test certificates (for example EN 10204 3.1) and traceability to relevant standards (EN designations such as 1.4571 / EN 10088 are commonly referenced).
• Post‑fabrication care: welded and heated surfaces should be cleaned and, where necessary, passivated to restore full corrosion resistance.

Standards and equivalent designations

Common ways of referring to this material are: EN 1.4571, 316Ti, AISI 316Ti and UNS S31635. Relevant European stainless steel standards include the EN 10088 series; for certifiable supply ask the supplier for specific standard references and the appropriate mill test documentation.

Ordering tips

If you are unsure which grade or finish you need, consider these steps before ordering: identify the operating environment (chemicals, temperature, chloride exposure), define mechanical and aesthetic requirements (thickness, finish), and decide whether you need certified material for regulatory compliance. For welded structures or components that will see elevated temperatures, 1.4571/316Ti is often the preferred choice over unstabilised 316. If in doubt, contact a technical advisor with details of the application so you receive the correct sheet specification.
