When sourcing stainless steel for high-temperature corrosive environments, 316Ti (UNS S31635, EN 1.4571) represents a specialized upgrade over standard 316 grades. The key differentiator? Titanium stabilization – a metallurgical enhancement that fundamentally changes how the material performs under thermal stress.
316Ti is an austenitic chromium-nickel-molybdenum stainless steel with titanium added at 5 times the carbon content minimum. This titanium addition serves one critical purpose: it prevents chromium carbide precipitation when the material is exposed to temperatures between 425-815°C (800-1500°F). In plain terms, without titanium, standard 316 stainless can become vulnerable to intergranular corrosion after welding or high-temperature service. 316Ti solves this problem at the atomic level. [1]
- Composition: Cr 16-18%, Ni 10-14%, Mo 2-3%, Ti 5×(C+N) minimum
- Tensile Strength: 620 MPa minimum
- Yield Strength: 248 MPa minimum
- Elongation: 54% minimum
- Hardness: 76 HRB maximum
- Max Service Temperature: 870-900°C intermittent, 925°C continuous
- Pitting Resistance Equivalent (PRE): 23.0 vs 304's PRE of 19.0 [1]
For Southeast Asian exporters selling on Alibaba.com, understanding these specifications is crucial because different buyers have vastly different requirements. A chemical plant operator in the Middle East needs different performance characteristics than a marine hardware distributor in Australia. 316Ti's value proposition centers on three pillars: stabilization advantages, temperature capabilities, and corrosion resistance.
316Ti stainless steel is reinforced with titanium and molybdenum, making it extra resistant to rust, corrosion, and heat. It's a premium upgrade over 304, though heavier and more expensive. [3]
