INCOLOY®合金 825 is a nickel-iron-chromium alloy with molybdenum, copper and titanium additions. Its chemistry is designed for broad corrosion resistance: nickel supports resistance to chloride-ion stress-corrosion cracking; molybdenum and copper improve resistance in reducing environments such as sulfuric and phosphoric acids; molybdenum also helps resist pitting and crevice corrosion; chromium supports resistance to oxidizing environments. Special Metals lists applications in sulfuric/phosphoric acid, sulfur-containing flue gas, sour oil/gas and seawater environments.

Machining Incoloy 825
825 is often supplied in an annealed condition with good ductility, but its nickel content still makes work hardening and heat concentration important machining concerns. Tooling that rubs instead of shears can harden the next layer. Long stringy chips can also interfere with bores, pockets and turning operations if evacuation is not engineered.
Typical 825 Parts We Machine
Common candidates include valve bodies, bonnets and trim; pump shafts and sleeves; chemical fittings; 流形; heat-exchanger hardware; 法蘭; seawater and marine components; sour-service oilfield parts; 儀器儀表機構; fasteners and custom acid-handling components. In mill-turn work, we frequently focus on concentric bores, 長螺紋, seal grooves and transition radii where tool wear can directly affect function.
825
825 is a corrosion-resistant, primarily solid-solution alloy. If strength requirements are moderate and corrosion is the main driver, 825 is often the simpler material.
925
925 builds on a similar corrosion-resistance concept but adds titanium and aluminum for precipitation hardening, producing much higher strength after aging. If a downhole or pressure component needs both high strength and sour-environment corrosion resistance, 925 may be considered. Use the design specification rather than substituting between them during purchasing.
焊接, Finishing and Inspection
825 has established conventional welding routes, and AlloyAccu can support projects that combine machining with fabrication where appropriate. Final sealing surfaces can be machined after welding to recover flatness/position. 磨削, polishing and electropolishing can be coordinated for functional finish needs. 捷運, 熱量/批次可追溯性, CoC, CMM reports, 粗糙度驗證, PMI/OES and optional NDT are available by project requirement.

鉻鎳鐵合金 825 問題
什麼是英科洛伊合金 825 用於?
It is used in chemical, 海洋, pollution-control and oil-and-gas equipment where resistance to reducing acids, 氯化物, localized corrosion and stress-corrosion cracking is important.
是因科洛伊合金嗎 825 a high-temperature creep alloy?
It has useful mechanical properties over a broad range, but it is not normally used where creep-rupture properties are the primary design factor. 800H/800HT are more directly associated with that duty.
是 825 difficult to machine?
It is machinable with conventional nickel-alloy practice, but work hardening, cutting heat and chip control require more discipline than common stainless steel.
製罐 AlloyAccu 機 Incoloy 825 valve and pump parts?
是的. Valve, pump, fitting, manifold, shaft and sealing-feature geometries are a strong fit for our CNC and inspection capabilities.
Can you provide NACE-related documentation?
We can supply material traceability and documents to the purchase specification. The customer must define the applicable NACE/ISO 15156 material requirements and acceptance criteria for the specific service.
