316Ti steel offers excellent solutions for welding and high temperature conditions. Standard stainless steels often face limitations in these areas. This article will explain why 316Ti steel is an ideal material for critical stainless steel pipe and fittings.
What is 316Ti Steel? The Stabilized 316!
316Ti steel (UNS S31635) is a titanium-stabilised version of 316 stainless steel with a similar composition to 316L. However, it has a small amount of titanium added to prevent chromium carbide precipitation. This process occurs during welding or high temperature exposure. It greatly improves intergranular corrosion resistance. As a result, it retains its properties better.
Core Advantages of 316Ti Steel
The titanium in 316Ti steel prevents sensitisation. This means that welds resist intergranular corrosion. Ensuring integrity after fabrication.
It has better mechanical properties and performs well at high temperatures. Compared to 316L, it resists creep and oxidation more effectively. Ensures stability in high temperature applications.
Its stabilized structure makes 316Ti Steel highly durable. It resists degradation over time. This reduces the need for frequent replacements. It minimizes maintenance costs for piping systems.
It is ideal for a variety of industries. These include chemical processing, pulp and paper, and oil and gas. It can handle corrosive media and high temperatures and is highly adaptable.
Despite its enhanced properties, 316Ti steel is easy to fabricate. It can be shaped, machined and welded, simplifying the manufacturing process. Make sure pipes and fittings are produced efficiently.

316Ti Steel in Stainless Steel Pipe and Fittings
316Ti steel is specifically designed for applications that cannot be met by standard 316L stainless steel. Suitable for welded parts exposed to corrosive environments.
Chemical Processing: 316 Ti steel pipe and fittings transport hot, corrosive chemicals. This includes medium concentrations of sulphuric acid.
Pulp and Paper Industry: Digesters and bleaching equipment. Resistant to acidic and chlorinated environments.
Oil and gas industry: heat exchangers and process pipework. Handles hot hydrocarbons and corrosive media.
Exhaust Systems: Automotive and industrial exhaust systems. Resistant to high temperatures and corrosive exhaust gases.
Power Generation: Components in power plants, especially for high temperature steam or corrosive flue gases, require 316Ti steel tubes.
Manufacturing and Sourcing 316Ti Steel Pipes and Fittings
Whilst generally suitable for welding, specific procedures are vital. Argon shielding gas is usually used. Low heat input minimises distortion.
Solution annealing (1010-1120 degrees Celsius followed by rapid cooling) is commonly used. Optimises mechanical properties and also enhances corrosion resistance.
316 Ti steel pipe and fittings conform to standard dimensions. This includes ASME B36.10 pipe and ASME B16.9/B16.11 fittings.
We work with suppliers who are experienced in speciality alloys and who understand the processing of the steel. Be able to guarantee the quality and performance of your products.
Always request material test reports to verify compliance with relevant standards. Include ASTM A312 (pipe) or ASTM A182 (forged fittings).
