Nickel 825 Nickel 825 Supplier & Features Nickel 825 is one of the toughest metals on the market and a great addition to any field. Its exceptional characteristics and improved strength, particularly compared to Nickel 800, make it a popular choice in various industries.” Stainless Shapes is a proud Nickel Alloy 825 supplier. If you have any questions regarding the metal or the content. Give us a call, and a representative will help you straight away. Common Applications – Chemical Processing, Air Pollution, Processing Metals, Offshore Production, Petroleum Farming, Waste Disposal, and of course, Nuclear Waste handling and Nuclear Fuel Reprocessing. Characteristics of Nickel 825 Chemical Composition – 825 is predominantly composed of nickel, following Iron and chromium, making it strong and durable. Especially when it comes to chemical and nuclear corrosion. Nickel: 38-46, Iron: 22(+), Chromium: 19.5-23.5, Molybdenum: 2.5-3.5, other elements of similar grades. Corrosion Resistance – As is typical of high nickel and high chromium metals, the corrosion resistance is excellent and among the highest in the market. Its exceptional capabilities and durability make the Alloy a frequent choice for use in both nuclear processing and chemical plants. Machinability – With the capability to withstand pitting under stress and stress corrosion cracking, Alloy 825 possesses impressive durability. Forming and machining it can present some difficulties, but its fabrication follows the typical process of nickel-base alloys and can be accomplished through formable and weldable methods.

Call - 800-748-9811 Frequently Asked Questions Is alloy 825 stainless steel? + Yes, Alloy 825 (Incoloy 825, UNS N08825) is classified as a nickel-iron-chromium alloy with molybdenum, copper, and titanium additions -- not a stainless steel. While it contains significant iron and chromium, its high nickel content (38-46%) places it in the nickel alloy family. It significantly outperforms stainless steel in many corrosive environments. What is alloy 825? + Alloy 825 is a nickel-iron-chromium alloy containing nominally 38-46% nickel, 19.5-23.5% chromium, 2.5-3.5% molybdenum, 1.5-3% copper, and a titanium addition for stabilization. Its combination of elements provides resistance to sulfuric acid, phosphoric acid, seawater, and reducing environments. Is alloy steel as good as stainless steel? + Alloy steel provides a different set of properties from stainless steel. Low-alloy steels (4140, 4340) have higher strength than stainless but much lower corrosion resistance. High-alloy steels including stainless offer corrosion resistance that low-alloy steels cannot match. Neither is universally better -- it depends on the application. What is the cheapest stainless steel alloy? + Among the cheapest stainless alloys are 409 and 430 ferritic grades (low nickel). Within the nickel alloy family, Monel 400 is generally the most economical. Alloy 825 is more expensive than stainless due to its high nickel, molybdenum, and copper content. Why is Inconel so expensive? + Inconel is expensive because the alloys contain high concentrations of nickel, chromium, molybdenum, and niobium -- all costly raw materials -- and require sophisticated melting (vacuum induction melting followed by vacuum arc remelting for critical applications) and processing. What are the disadvantages of using Inconel? + The main disadvantages of Inconel alloys include high material and processing cost, difficulty in machining (low thermal conductivity, work-hardening tendency), challenging weldability for some grades, and very long lead times for non-standard sizes. What are the 4 types of stainless steel? + The four types of stainless steel are austenitic, ferritic, martensitic, and precipitation-hardening. Alloy 825 is not a stainless steel -- it is a nickel alloy. Classifying by family: Alloy 825 is a corrosion-resistant nickel alloy. What is the difference between Inconel 925 and 825? + Inconel 925 is an age-hardenable nickel alloy used primarily in oil and gas OCTG applications. Inconel 825 (Alloy 825) does not harden by aging. The 925 designation has higher strength due to its precipitation-hardening capability via titanium and aluminum additions. What is the difference between 925 and 825 silver? + In jewelry, 925 refers to sterling silver (92.5% silver), not related to nickel alloy 825. The two designations are from entirely different numbering systems -- one for precious metal purity, one for industrial alloy UNS identification. What is Inconel 825 used for? + Incoloy 825 (Alloy 825) is used in chemical processing, oil and gas production, offshore pipelines, marine heat exchangers, spent nuclear fuel reprocessing equipment, and phosphoric acid production -- wherever resistance to both oxidizing and reducing corrosive environments is required simultaneously.
