Alloy 400
UNS N04400 · Nickel-copper alloy
A nickel-copper alloy evaluated for selected reducing environments, alkalis, marine duties, and process streams where its specific corrosion profile is beneficial.
Alloy 600
UNS N06600 · Nickel-chromium alloy
A nickel-chromium alloy considered for oxidation resistance and selected high-temperature or corrosive environments.
Alloy 625
UNS N06625 · Nickel-chromium-molybdenum-niobium
A nickel alloy combining useful strength with broad corrosion resistance for demanding process, offshore, and high-temperature applications.
Alloy 800 / 800H
UNS N08800 / N08810 · Nickel-iron-chromium
Alloy 800 is used for oxidation and carburization resistance, while 800H uses controlled chemistry and heat treatment for elevated-temperature creep and rupture properties.
Alloy 825
UNS N08825 · Nickel-iron-chromium-molybdenum-copper
A nickel-iron-chromium alloy with molybdenum and copper, evaluated for selected acid, chloride, and pollution-control environments.
Alloy C276
UNS N10276 · Nickel-molybdenum-chromium-tungsten
A highly alloyed nickel material considered for aggressive chemical process environments involving mixed contaminants and localized-corrosion risk.
Alloy 400 is a nickel-copper route; 600 is a nickel-chromium alloy; 625 adds molybdenum and niobium; 800/800H targets oxidation and elevated-temperature strength; 825 adds molybdenum and copper for selected corrosive media; C276 is a nickel-molybdenum-chromium alloy for severe chemical service.
Procurement comparison
Translate the material name into order data.
The same commercial alloy name can map to different forging, fitting, and casting designations. State the complete material and product-form specification.
| Grade | Selection cue | Typical project context | Procurement control |
|---|---|---|---|
| Alloy 400 | Nickel-copper service | Marine systems, caustic service, salt production, hydrofluoric-acid-related duties, and selected chemical processing. | Confirm UNS N04400, product-form specification, fabrication route, and compatibility with the exact oxidizing or reducing conditions. |
| Alloy 600 | Oxidation and heat | Thermal processing, furnace equipment, chemical equipment, and selected high-temperature chloride duties. | State UNS N06600, solution condition, design temperature, product standard, and required testing. |
| Alloy 625 | Strength plus corrosion | Offshore and subsea systems, chemical processing, pollution control, and selected sour or chloride-bearing service. | Define the required heat-treated condition, service temperature, product form, NDE, and project-specific corrosion tests. |
| Alloy 800 / 800H | Elevated-temperature duty | Heat exchangers, furnace components, petrochemical heaters, and high-temperature process equipment. | Do not interchange 800 and 800H without checking design temperature, allowable stress, grain-size requirements, and code listing. |
| Alloy 825 | Acid and process corrosion | Acid processing, pickling equipment, pollution control, oil and gas, and chemical process piping. | Document the acid concentration, contaminants, temperature, welding route, and required corrosion evidence. |
| Alloy C276 | Severe chemical service | Chemical processing, pollution control, waste treatment, acid production, and demanding reactor or transfer systems. | Confirm UNS N10276, product specification, heat treatment, welding controls, PMI, and any corrosion-test acceptance criteria. |

What is Nickel Alloy?
Nickel alloys are selected when a process environment exceeds the practical corrosion or temperature capability of common steels. Alloy chemistry, product form, heat treatment, fabrication, and the exact media all matter; trade names alone are not a complete specification.
How do I choose between the listed Nickel Alloy grades?
Alloy 400 is a nickel-copper route; 600 is a nickel-chromium alloy; 625 adds molybdenum and niobium; 800/800H targets oxidation and elevated-temperature strength; 825 adds molybdenum and copper for selected corrosive media; C276 is a nickel-molybdenum-chromium alloy for severe chemical service.
Can the same alloy designation be used for flanges, fittings, and valves?
The same alloy family can be used across a pressure system, but the ASTM grade designation can change with product form and manufacturing route. Confirm the forging, wrought-fitting, or casting specification together with the dimensional standard and pressure rating.
What should a Nickel Alloy RFQ include?
Include component type, exact grade and UNS where applicable, ASTM product specification, size, schedule or bore, pressure class, facing or end connection, quantity, service conditions, heat treatment, testing, certification, marking, and inspection requirements.
Does the material standard also define flange, fitting, or valve dimensions?
Usually not. The purchase specification normally combines a material standard with a dimensional or pressure-rating standard such as ASME B16.5, B16.9, B16.11, B16.34, an EN or DIN standard, or a project-specific specification.
