پودر سوپرآلیاژ پایه نیکل IN825 برای فرآوری شیمیایی، نفت و گاز، مهندسی دریایی و پوششهای مقاوم در برابر خوردگی
مروری بر محصولات
پودر سوپرآلیاژ پایه نیکل GREENSTONE IN825 is a high-performance, corrosion-resistant metal powder developed for components and protective coatings operating in aggressive chemical, marine, oil & gas, and industrial environments.
IN825 is a globally recognized nickel-iron-chromium alloy with molybdenum, copper and titanium additions. Its alloy chemistry provides excellent resistance to reducing and oxidizing acids, stress-corrosion cracking, pitting, crevice corrosion and general corrosion.
With spherical morphology and controlled particle size distribution, GREENSTONE IN825 powder is suitable for thermal spraying, laser cladding, Directed Energy Deposition (DED), surface engineering and compatible metal additive manufacturing processes. It is particularly valuable where long-term corrosion resistance is more important than the very high-temperature strength typically associated with alloys such as IN718.
برنامه های کاربردی معمولی عبارتند از chemical processing equipment, oil and gas components, pipelines, valves, pumps, marine equipment, acid-handling systems and corrosion-resistant industrial coatings.
مقاومت در برابر خوردگی عالی
IN825 is specifically designed for severe corrosive environments. The high nickel content provides resistance to chloride-ion stress-corrosion cracking, while chromium improves resistance to oxidizing environments. Molybdenum contributes to resistance against pitting and crevice corrosion, particularly in reducing environments.
Suitable for Acid-Resistant Industrial Components
The combination of nickel, chromium, molybdenum and copper makes IN825 particularly suitable for components exposed to sulfuric acid, phosphoric acid and other aggressive chemical media under appropriate service conditions.
This makes the alloy highly relevant to chemical reactors, processing equipment, piping systems, valves, pumps and related industrial components.
Optimized for Surface Engineering
GREENSTONE IN825 powder can be used to produce corrosion-resistant surfaces on components where manufacturing the entire part from a nickel alloy may not be economically necessary.
فرآیندهایی مانند laser cladding and DED can metallurgically deposit IN825 onto selected component surfaces, supporting localized protection, repair, dimensional restoration and functional surface enhancement.
Spherical Powder Morphology
The spherical powder morphology provides good flowability and consistent powder feeding, helping maintain stable material delivery during automated processing.
Key powder characteristics include:
- کرویت بالا
- جریان پذیری خوب پودر
- توزیع اندازه ذرات کنترل شده
- تغذیه پودر پایدار
- Consistent deposition behavior
- Customizable particle size ranges for different processes
Strong Performance in Oil & Gas Applications
IN825 is widely applicable to components exposed to corrosive fluids and demanding process environments in the صنعت نفت و گاز, including pipelines, valves, pumps, fittings and other process equipment.
Its combination of corrosion resistance and mechanical stability makes it suitable for protective coatings as well as selected component manufacturing and repair applications.
Marine & Offshore Corrosion Protection
IN825 provides useful resistance in chloride-containing environments, making the alloy suitable for selected marine, offshore and seawater-related equipment where corrosion protection and long service life are important.
کاربردهای پردازش شیمیایی
The alloy is particularly attractive for chemical processing environments involving corrosive media. Typical applications include:
- Chemical reactors and processing equipment
