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

Mechanical Properties:

Physical Properties:

Applications:

• High-Temperature and High-Pressure Environments such as boilers, heat exchangers, superheater tubes, and furnace parts where elevated temperature strength is required
• Petrochemical and Chemical Processing where resistance to acidic and chloride-containing environments is needed along with high-temperature capabilities
• Nuclear Power Plants which require high-temperature performance and resistance to corrosive cooling agents
• Oil and Gas Industry where equipment is subject to corrosive substances, high temperatures, and high pressures.
• Heat Exchangers which handle corrosive fluids at elevated temperatures
• Furnace Parts and Equipment used in incinerators, burners, and heating elements that operate at elevated temperatures
