316Ti Stainless Steel in Chemical Processing | Gangsteel

 

In the demanding world of chemical processing, where equipment faces corrosive chemicals, high temperatures, and intense operational conditions, material selection is critical. 316Ti stainless steel is a top choice for its exceptional corrosion resistance, high-temperature stability, and weldability, making it ideal for reactors, tanks, and piping systems. As a leading supplier, Gangsteel offers high-quality 316Ti stainless steel in forms like sheets, plates, bars, and pipes, compliant with standards such as ASME SA240 and ASTM A240 316Ti. This guide explores why 316Ti stainless steel excels in chemical processing, detailing its properties, applications, and advantages.

 

1. Why 316Ti Stainless Steel for Chemical Processing?

316Ti stainless steel is an austenitic stainless steel alloy, a variant of 316 stainless steel, enhanced with titanium (0.4–0.7%) to prevent intergranular corrosion during welding or exposure to high temperatures (425–815°C). This titanium stabilization, combined with molybdenum’s corrosion resistance, makes 316Ti stainless steel a reliable choice for chemical processing environments, where equipment must withstand aggressive chemicals like acids, chlorides, and solvents.

Gangsteel’s 316Ti products meet standards like ISO TR15510, ensuring performance in harsh conditions.

Key Features for Chemical Processing

  • Corrosion Resistance: Resists pitting and crevice corrosion in chloride-rich and acidic environments.
  • High-Temperature Stability: Maintains integrity up to 900°C, ideal for heated chemical processes.
  • Weldability: Titanium ensures robust welds without sensitization, critical for stainless cutting sheet parts.
  • Durability: Long service life reduces downtime and maintenance costs.
