What is S32168 Stainless Steel shell and tube heat exchanger?
S32168 stainless steel, also known as 06Cr18Ni11Ti (or the old grade 0Cr18Ni11TI), is a austenitic Ni-Cr-Ti stainless steel suitable for heat exchanger tubes due to its high temperature resistance, creep resistance, and wear resistance. It is specified in the Chinese national standard GB/T13296 for shell and tube heat exchangers and is used in various industrial applications, including conveying pipelines, acid containers, and equipment linings.
Key Characteristics
Material Type: Ni-Cr-Ti austenitic stainless steel.
Standards: Corresponds to the Chinese standard GB/T13296.
Properties: Exhibits high resistance to high temperatures and creep, along with good wear resistance.
Applications: Used in shell and tube heat exchangers, conveying pipelines, wear-resistant acid containers, and equipment linings.
Comparison of S32168 and TP316 Heat Exchanger Tubes
S32168 is a Ni-Cr-Ti austenitic stainless steel with high abrasion, high-temperature, and creep resistance, making it suitable for wear-resistant, high-temperature, and high-corrosion applications like specific industrial equipment, whereas TP316 is a molybdenum-bearing austenitic stainless steel (ASTM A249 TP316) excellent for general heat exchanger applications, especially in chloride-containing and pitting-prone environments due to its enhanced molybdenum content. The key difference is S32168's titanium addition for high-temperature stability and abrasion resistance, while TP316 relies on molybdenum for superior pitting resistance in acidic and chloride media.
