Product Description
ASTM A213 TP316H Stainless Steel Seamless Tube for Heat Exchanger, Superheater
TP316H is a high-temperature grade of stainless steel, specifically formulated for use in boiler, superheater, and heat exchanger tubes. The "H" in TP316H denotes a higher carbon content compared to standard TP316, which enhances the material's strength at elevated temperatures. This makes it suitable for high-temperature applications where TP316 or TP316L may not provide sufficient strength.
TP316H maintains good corrosion resistance in a variety of environments, especially those containing chlorides and acidic substances. The addition of molybdenum enhances its resistance to pitting and crevice corrosion in chloride environments, which is beneficial in high-temperature, corrosive applications.
Chemical Composition
- Chromium (Cr): 16 - 18%
- Nickel (Ni): 10 - 14%
- Molybdenum (Mo): 2 - 3%
- Carbon (C): 0.04 - 0.10% (higher than 316 or 316L for improved high-temperature strength)
- Manganese (Mn): 2% max
- Silicon (Si): 1% max
- Phosphorus (P): 0.045% max
- Sulfur (S): 0.03% max
- Iron (Fe): Balance
