ER 16-8-2 is a specialized stainless steel welding filler metal, an austenitic alloy with approximately 16% Chromium, 8% Nickel, and 2% Molybdenum, offering excellent high-temperature strength, creep resistance, and resistance to hot cracking, making it ideal for thick-sectioned, high-pressure piping and furnace parts in power generation, petrochemical, and chemical industries, bridging properties between 308H and 316H steels for robust service up to 800C.
Key Characteristics:
Composition: Controlled levels of Cr (around 16%), Ni (around 8%), and Mo (around 2%).
Performance: Offers superior high-temperature performance, creep resistance, and thermal embrittlement resistance compared to standard matching grades.
Hot Cracking Resistance: Its controlled ferrite content provides excellent resistance to centerline cracking in restrained welds, notes this article from cancerinstitutewia.in.
Cryogenic Toughness: Also provides good toughness at very low temperatures, enabling use from cryogenic to high-temperature service.
Applications:
Welding heavy-walled stainless steel pipes and components for steam, catalytic crackers, and furnaces.
Ideal for applications in power plants, refineries, and chemical processing.
Used for welding 304H, 316H, and 347H stainless steels, especially in thick sections where matching weld metals struggle.
Why It's Used: ER 16-8-2 acts as a hybrid, combining good high-temperature properties of 316H with improved hot ductility, making it a preferred choice for demanding applications where standard welds might fail due to thermal stress or cracking, according to this document from nickelalloys.com
