TP316Ti

Material

  • TP316Ti, UNS S31635, 1.4571, X6CrNiMoTi17-12-2, 06Cr17Ni12Mo2Ti

Overview

TP316Ti is a high performance austenitic stainless steel pipe that incorporates titanium elements. It possesses properties such as resistance to inter-granular corrosion, high temperature resistance, and high strength, and widely used in extreme working conditions in fields like chemical engineering, petroleum, and food processing.

Characteristics

    • TP316Ti is a material that adds titanium (Ti) element to 316L, significantly enhancing its resistance to inter-granular corrosion, and maintaining stable performance even after welding.

      Its key characteristics include:

    • High-temperature resistant: Can work for a long time in high-temperature steam and hot oil media
    • Strong corrosion resistance: Resists acid, alkali, salt and seawater erosion
    • Excellent mechanical properties: Tensile strength ≥ 530 MPa, elongation ≥ 40%
    • Non-toxic and environmentally friendly: Complies with hygiene requirements in the food and medical fields

Typical Application

Chemical/Pharmaceutical: Suitable for transporting strong acids and organic solvents, in compliance with GMP standards.
Petroleum and natural gas: Oil well casings, refining equipment, resistant to high pressure and corrosion.
Food processing: Milk products, beverage conveying pipelines, non-toxic and easy to clean.
Marine engineering: Offshore platforms, submarine pipelines, resistant to seawater corrosion
