Alloy 725 is a nickel-chromium alloy with significant additions of molybdenum, niobium and titanium, supplied in the hot worked, annealed and age-hardened condition. It is age-hardened to achieve extremely high strength, approximately twice that of Alloy 625 in the annealed condition, through the precipitation of \u03d2\u201d phase during a controlled heat treatment process. As this high strength is achieved by ageing rather than cold working, it retains excellent ductility and toughness, and this approach is useful for large or non-uniform sections that cannot be strengthened through cold working.<\/p>\n", "specifications": { "united_states": [ "ASTM B637", "UNS N07725" ] }, "features": [ "Suitable for use in highly corrosive sour oil and gas wells, approved under NACE MR 1075", "Excellent corrosion resistance in a wide variety of corrosive environments including seawater and industrial acids", "Age hardened for extremely high strength", "Good ductility and toughness", "Excellent resistance to stress corrosion cracking" ], "applications": [ "Downhole equipment for corrosive\/sour service", "Oil and gas hangers, connectors", "Fasteners, especially in marine applications", "Chemical process equipment", "Agitators", "Valve stems" ], "file": { "composition": { "ID": 16443, "id": 16443, "title": "Alloy 725 - Chem Rev1", "filename": "Alloy-725-Chem-Rev1.xls", "filesize": 26624, "url": "https:\/\/www.langleyalloys.com\/wp-content\/uploads\/2017\/04\/Alloy-725-Chem-Rev1.xls", "link": "https:\/\/www.langleyalloys.com\/us\/products\/alloy-725\/alloy-725-chem-rev1-2\/", "alt": "", "author": "3", "description": "", "caption": "", "name": "alloy-725-chem-rev1-2", "status": "inherit", "uploaded_to": 16336, "date": "2017-04-04 10:30:22", "modified": "2017-04-04 10:30:22", "menu_order": 0, "mime_type": "application\/vnd.ms-excel", "type": "application", "subtype": "vnd.ms-excel", "icon": "https:\/\/www.langleyalloys.com\/wp-includes\/images\/media\/spreadsheet.png" }, "mechanical": { "ID": 16444, "id": 16444, "title": "Alloy 725 - Mech Rev1", "filename": "Alloy-725-Mech-Rev1.xls", "filesize": 27648, "url": "https:\/\/www.langleyalloys.com\/wp-content\/uploads\/2017\/04\/Alloy-725-Mech-Rev1.xls", "link": "https:\/\/www.langleyalloys.com\/us\/products\/alloy-725\/alloy-725-mech-rev1-2\/", "alt": "", "author": "3", "description": "", "caption": "", "name": "alloy-725-mech-rev1-2", "status": "inherit", "uploaded_to": 16336, "date": "2017-04-04 10:30:23", "modified": "2017-04-04 10:30:23", "menu_order": 0, "mime_type": "application\/vnd.ms-excel", "type": "application", "subtype": "vnd.ms-excel", "icon": "https:\/\/www.langleyalloys.com\/wp-includes\/images\/media\/spreadsheet.png" } } }

It can be supplied in the hot worked, annealed and age-hardened condition. It is age-hardened to achieve extremely high strength, approximately twice that of Alloy 625 in the annealed condition, through the precipitation of \u03d2\u201d phase during a controlled heat treatment process. As this high strength is achieved by ageing rather than cold working, it retains excellent ductility and toughness, and this approach is useful for large or non-uniform sections that cannot be strengthened through cold working.\nAlloy 725 has very similar corrosion resistance to Alloy 625, and so is utilised in a wide range of very corrosive environments. The high nickel content ensures resistance to stress corrosion cracking, combined with molybdenum to strongly resist reducing environments such as sulphuric and phosphoric acids, chromium to resist oxidising environments such as nitric acid, titanium to inhibit intergranular corrosion, and overall resistance to pitting and crevice corrosion. The overall combination of alloying elements provides excellent resistance to conditions found in sour oil and gas wells, containing carbon dioxide, chlorides and hydrogen sulphide, and is approved under NACE MR 1075 for such applications.\n","short_description":"Alloy 725 is a nickel-chromium alloy with significant additions of molybdenum, niobium and titanium, supplied in the hot worked, annealed and age-hardened condition.

Nickel

Nickel alloys can offer enhanced corrosion resistance, toughness, strength at high and low temperatures, and interesting magnetic, thermal and electronic properties compared with other metals. Due to their higher nickel content compared with stainless steels, they can be appreciably more expensive, but find uses in more demanding applications from gas turbines to chemical plants and oil & gas industry components.

Nickel-Copper Alloys – Monel®

Nickel – copper alloys such as Alloy 400 and Alloy K-500, also known as Monel K500, (Special Metals Corporation’s family of Nickel-Copper alloys is known as Monel®) are based predominantly on nickel and copper, with smaller additions of manganese and iron. They are used where a higher strength is required compared to pure nickel, and resist corrosion in a wide range of environments. They can be fabricated readily by hot and cold working, machining, and welding. Nickel-Copper alloys find wide application in oil refining and marine applications where long corrosion-free life is required. Due to the good thermal conductivity of the alloys, they are also frequently used for heat exchangers where sea water is one of the fluids concerned.

Nickel-Iron-Chromium Alloys – Incoloy®

Nickel-Iron-Chromium alloys such as Alloy 825, also known as Incoloy 825, (Special Metals Corporation’s family of Nickel-Iron-Chrome alloys is known as Incoloy® ) were developed to provide a more cost-effective solution for applications requiring high-temperature and corrosion resistance – achieved by lowering the nickel content. Selectively alloying with other elements can greatly improve their performance in certain environments. For instance, Alloy 825 also contains molybdenum and copper to improve resistance to strongly reducing environments, such as those containing sulphuric and phosphoric acids.

Nickel-Chromium Super Alloys – Inconel®

Nickel-Chromium super alloys such as Alloy 625, also known as Inconel 625, and Alloy 718, also known as Inconel 718, (Special Metals Corporation’s family of Nickel-Chromium alloys is known as Inconel®) are typically used in high-temperature applications. When heated, they form a thick and stable passivating oxide layer protecting the surface from further attacks. These alloys retain their strength over a wide temperature range, particularly at elevated temperatures where aluminium and steel would otherwise succumb to creep failure. Varying levels of high-temperature strength can be developed by solid solution strengthening or precipitation strengthening (with niobium additions).

Alloy 625:

Alloy 625 is a nickel-chromium-molybdenum-niobium alloy (NiCr22Mo9Nb), supplied in the hot worked and annealed condition. It achieves high-strength levels from the solid solution effects of Molybdenum and Niobium (Colombium) from room temperature up to 800°C.

It is particularly useful in situations where oxidation resistance and avoidance of pitting is required. In the annealed condition, it is fully austenitic and is suitable for machining. It provides excellent corrosion resistance in a wide variety of severe corrosive environments due to its high alloy content.

Alloy K500:

Alloy K500 is a precipitation-hardenable nickel-copper alloy. Although Langley Alloys supply Alloy K500 in all conditions, we predominantly supply material in the Hot Worked and Precipitation Treated condition, which offers the optimum combination of high strength and ductility across the size range. The increased properties are obtained by adding aluminium and titanium to the nickel-copper base, and by heating under controlled conditions so that particles of ‘ϒ’ Ni₃ (Ti, Al) are precipitated throughout the matrix. The thermal processing used to effect precipitation is commonly called age hardening or ageing.
