Product Detail

Introduction

ASTM A312 TP316Ti seamless pipes are designed for extreme applications requiring superior resistance to intergranular corrosion and elevated temperatures. With the addition of titanium (Ti) stabilization, this advanced alloy prevents carbide precipitation during welding or prolonged high-heat exposure, ensuring unmatched longevity in aggressive conditions. TP316L is a low-carbon variant of austenitic stainless steel (316L grade) commonly used in tubing and piping systems. It contains 16-18% chromium, 10-14% nickel, 2-3% molybdenum, and a maximum 0.035% carbon, enhancing corrosion resistance—particularly against chlorides and acids.

Key Features

Titanium-Stabilized Durability: Ti minimizes sensitization risks, outperforming standard 316 in welded or cyclic thermal processes (up to 800°C / 1472°F).

Enhanced Corrosion Resistance: 16-18% chromium, 10-14% nickel, and 2-3% molybdenum combat chlorides, sulfuric acid, and marine environments.

High Mechanical Strength: Tensile strength ≥515 MPa, yield strength ≥205 MPa, ideal for high-pressure systems.

Frequently Asked Questions

What is the difference between TP316Ti and standard 316 stainless steel?

TP316Ti is stabilized with titanium (Ti). This addition minimizes sensitization risks and prevents carbide precipitation during welding or prolonged high-heat exposure (up to 800°C / 1472°F), outperforming standard 316 in cyclic thermal processes.

What is the chemical composition of ASTM A312 TP316Ti?

According to standard specifications, TP316Ti contains 16.00-18.00% Chromium, 10.00-14.00% Nickel, and 2.00-3.00% Molybdenum, with a maximum carbon content of 0.08% and titanium stabilization.

What are the mechanical properties of TP316Ti?

It features a minimum tensile strength of 515 MPa, a minimum yield strength of 205 MPa, a minimum elongation of 35%, and a maximum hardness of 90 HRB (Rockwell B) or 187 HB (Brinell).

In which industries are TP316Ti seamless pipes applied?

These pipes are commonly used in aggressive environments including Chemical Industries, Thermal & Nuclear Power Plants, Fertilizer Plants, Aerospace, Food & Dairy Plants, Paper Industries, Oil & Gas Exploration, Desalination Plants, and Pharmaceutical Plants.

What are the equivalent grades of ASTM A312 TP316Ti?

Equivalent global grades include S31635 (UNS/USA), X6CrNiMoTi17-12-2 (ISO/DIN), 1.4571 (EN), SUS 316Ti (JIS), and 06Cr17Ni12Mo2Ti (GB/IS).

What quality inspections do these pipes undergo?

The seamless pipes undergo 100% PMI testing, are certified under EN10204.3.1B Mill Test Certificates, and accept third-party inspections to ensure quality compliance.
