Pipe Line Connection Nickel Alloy Hex Nut Alloy 625/825/C276 Fastener With Machining Production

Application:

1. gas-turbine components (blades, rings, discs)

2. bolts

3. tube supports in nuclear generators

4. exhaust valves in internal combustion engines

5. die-casting inserts and cores

6. other applicaiton in marine, aircraft, automotive and electrical

Features:

Alloy 625 has excellent strength at temperatures up to 816℃. At higher temperatures, its strength is generally lower than that of other solid solution strengthened alloys. Alloy 625 has good oxidation resistance at temperatures up to 980℃ and shows good resistance to aqueous corrosion, but is relatively moderate compared to other more capable corrosion resistant alloys.

Alloy 825 has excellent resistance to chloride-ion-induced stress corrosion cracking, reducing environments containing phosphoric and sulfuric acids, oxidizing environments containing nitric acid and nitrates, and pitting, crevice corrosion and intergranular corrosion. It has good mechanical properties at cryogenic temperatures to moderately high temperatures up to 538℃

Alloy C-276 has excellent resistance to localized corrosion, stress corrosion cracking, and to both oxidizing and reducing media, thus making it suitable for a wide variety of chemical process environments, including ferric and cupric chlorides, hot contaminated media (organic and inorganic), formic and acetic acids, seawater and brine solutions. It is one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.

Through more than ten years of research and development, the production of MTSCO Alloy technology and efficiency of various materials have been greatly improved. The enterprise has passed the national quality management system certification of weapons and equipment, obtained more than 24 authorized patents, participated in the revision of 9 national standards and 3 industry standards. MTSCO has actively participated in the civil military integration project, provided high-temperature alloy materials for a PLA unit, provided high-quality special alloy materials for China ordnance industry group, and provided new low expansion alloy materials for China aviation industry. It has been successfully applied to the domestic large aircraft C919, replacing imports with domestic ones, breaking the foreign blockade monopoly and filling the domestic blank.
