316Ti: A common abbreviation indicating a titanium-containing modification of 316 stainless steel.
S31635: The US UNS number (Unified Numbering System) is the only standard designation for this material.
Type: Austenitic stainless steel.
Core Improvement: Based on standard 316 stainless steel, titanium (Ti) is added (typically ≥5×C%, but ≤0.70%).
The core value of 316Ti (S31635) stainless steel pipe lies in its excellent resistance to intergranular corrosion, imparted by titanium stabilization, especially in the welded state or after moderate heating. While retaining the excellent overall performance of standard 316 stainless steel (general corrosion resistance, pitting corrosion resistance, formability, and weldability), it addresses the key challenges of welding and high-temperature service. This makes it a preferred material for piping systems in the chemical, petrochemical, and energy (boilers, heat exchangers), requiring welded structures and potentially exposed to corrosive media or moderate-to-high-temperature environments.
