Nickel Alloy Fasteners

The nickel content gives it excellent resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance to alkaline solutions.

In strong oxidizing solutions like hot, concentrated nitric acid, 600 has poor resistance.

Alloy 600 is non-magnetic, has excellent mechanical properties and a combination of high strength and good workability and is readily weldable.

It is resistant to a wide range of corrosive media. The chromium content gives better resistance than Alloy 200 and 201 under oxidizing conditions, at the same time the high nickel gives good resistance to reducing conditions.

It is virtually immune to chlorine ion stress corrosion cracking. Demonstrates adequate resistance to organic acids such as acetic, formic and stearic. Excellent resistance to high purity water used in primary and secondary circuits of pressurized nuclear reactors.

It has little or no attack occurs at room and elevated temperatures in dry gases, such as chlorine or hydrogen chloride. At temperatures up to 550C in these media, this alloy has been shown to be one of the most resistant of the common alloys.

At elevated temperatures the annealed and solution annealed alloy shows good resistance to scaling and has high strength. The alloy also resists ammonia bearing atmospheres, as well as nitrogen and carburizing gases.

Under alternating oxidizing and reducing conditions the alloy may suffer from selective oxidation.

It is usually used in Thermocouple sheaths. Ethylene dichloride (EDC) cracking tubes.

Nickel Alloy 600, also sold under the brand name Inconel 600.

INCONEL 625 is a nickel-chromium alloy with an addition of molybdenum and niobium. These additions give the alloy better mechanical properties and better corrosion resistance without having to harden the material.

Alloy 625 is a popular nickel-chromium alloy that offers users a high level of strength and ease of fabrication.

INCONEL 625 is used in offshore and aerospace industries, but also in pollution control equipment.

Because of its versatility, a number of industries utilize alloy 625 including nuclear power production, marine/boating/undersea, and aerospace.

Inconel 625 alloy is used for heat shields, furnace hardware, gas turbine engine ducting, combustion liners and spray bars, chemical plant hardware and special seawater applications.

Inconel 625 also has resistance to various aqueous media causing localized corrosion, stress corrosion cracking and other forms of attack.

For high temperature applications up to 1,000 ¡ãC (1,832 ¡ãF), the solution treated variant (grade 2) acc. to ASME Code for Pressure Vessels is used.

Within in these critical industries you can find Nickel Alloy 625 and Inconel 625 in various applications including:Nuclear reactor-cores and control-rod components, Wire rope for cables and blades on Naval crafts such as gunboats and subs, and Oceanographic equipment etc.

High solution anneal, a treatment at 2000/2200oF (1095/1205oC) for a time depending upon section size, but soaking for a maximum of one hour, and cooling in air or a faster medium.

Its outstanding strength and toughness in temperature ranges from cryogenic temperatures to high temperature up to 2000¡ã F (1093¡ã C) are derived primarily from the solid solution effects of the refractory metals Columbium and molybdenum in a nickel-chromium matrix.

Nickel chromium alloy 625 has excellent resistance to pitting and crevice corrosion, high corrosion-fatigue strength, high tensile strength as well as resistance to stress corrosion cracking to chloride ions ¡ª making it an excellent choice for sea-water applications.

Inconel is used in aerospace applications as well as marine applications. Common applications for this alloy are springs, seals, bellows for submerged controls, electrical cable connectors, fasteners, flexure devices, and oceanographic instrument components.

Alloy 625 has excellent weldability and is frequently used to weld AL-6XN? alloy. Matching filler metals are also used to join dissimilar metals.

Alloy 625 is a nickel-chromium alloy known and used for corrosion and oxidation resistance, and its high strength and fabricability.

The chromium content of this alloy results in superior resistance to oxidizing environments. The high molybdenum content makes alloy 625 very resistant to pitting and crevice corrosion.

Material examination indicated no crack and minor porosity were detected through and along the interface of two materials and the following as-deposited In625.

Inconel 625 is a nickel-based super alloy with high strength properties and resistance to corrosion, including H2S and CO2, and elevated temperatures.

The alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion. Used in chemical processing, aerospace and marine engineering, pollution-control equipment, and nuclear reactors.

The results reveal that Inconel 625 is excellent in resist the corrosion attack in seawater. However, at increasing temperature, the corrosion resistance of this metal decrease.

Inconel 625 is a solid solution strengthened Ni-base superalloy, which has high strength at high temperatures.
