316H stainless steel is a type of austenitic stainless steel with the UNS number S31609. It is standardized under AISI and ASTM specifications and is known for its enhanced properties compared to standard 316H Stainless Steel .
Chemical Composition
The chemical composition of 316H Stainless Steel includes:
●
Carbon (C): 0.04~0.10
●
Manganese (Mn): ≤2.00
●
Silicon (Si): ≤0.75
●
Chromium (Cr): 16.0~18.0
●
Nickel (Ni): 10.0~14.0
●
Phosphorus (P): ≤0.045
●
Sulfur (S): ≤0.03
●
Molybdenum (Mo): 2.0~3.0
Key Properties
1.
High Temperature Strength: The higher carbon content in 316H provides improved strength at elevated temperatures, making it suitable for applications requiring high-temperature performance.
2.
Corrosion Resistance: Like other 316 grades, 316H offers excellent resistance to corrosion, particularly in environments with chlorides, making it suitable for marine and chemical processing applications.
3.
Weldability: It possesses good welding properties and can be welded using various standard welding methods. However, due to its higher carbon content, it may require post-weld heat treatment to avoid sensitization and intergranular corrosion.
4.
Austenitic Structure: The austenitic structure of 316H Stainless Steel grants it excellent toughness, even at low temperatures.
Applications
316H Stainless Steel is widely used in industries such as:
●
Petrochemical and natural gas
●
Chemical processing
●
Power generation
●
Paper and pulp production
●
Marine environments
Comparison with 316 and 316L
316H has a higher carbon content compared to 316 and 316L, which enhances its high-temperature strength. However, this also means it is more susceptible to sensitization during welding. 316L, with its lower carbon content, offers better resistance to intergranular corrosion but may not perform as well in high-temperature applications.
Heat Treatment
●
Melting Point: 1375~1450°C
●
Solution Annealing: 1010~1150°C
Standards and Grades
316H Stainless Steel is recognized under various international standards, including:
●
ASTM A959, A240/A240M
●
SAE J405
●
DIN 1.4436 (German standard)
●
EN X3CrNiMO17-13-3 (European standard)
