Stainless steel AISI 316ti / EN 1.4571

✅ General Technical Characteristics

Stainless steel AISI 316Ti (EN 1.4571) is a titanium-stabilized austenitic stainless steel that offers excellent corrosion resistance, particularly in aggressive environments containing chlorides and acids. The addition of titanium enhances resistance to intergranular corrosion, making this steel suitable for high-temperature applications and prolonged exposure to harsh conditions.

Main Characteristics:

• High corrosion resistance, especially in chloride and acidic environments.
• Enhanced resistance to intergranular corrosion due to titanium stabilization.
• Excellent mechanical strength and heat resistance.
• Good weldability without risk of carbide precipitation.
• Suitable for use in high-temperature environments.

🔬 Chemical Composition AISI 316Ti / EN 1.4571 (%):

• Carbon (C): ≤ 0.08
• Silicon (Si): ≤ 1.0
• Manganese (Mn): ≤ 2.0
• Phosphorus (P): ≤ 0.045
• Sulfur (S): ≤ 0.015
• Chromium (Cr): 16.5 – 18.5
• Nickel (Ni): 10.5 – 13.5
• Molybdenum (Mo): 2.0 – 2.5
• Titanium (Ti): ≥ 5 x C

💡 The presence of titanium improves high-temperature performance and prevents intergranular corrosion after welding.
