Galvanic corrosion potential is a measure of how dissimilar metals will corrode when placed against each other in an assembly. Metals close to one another on the chart generally do not have a strong effect on one another, but the farther apart any two metals are separated, the stronger the corroding effect on the one higher in the list.
High-performance age hardenable nickel alloys solve must be corrosion resistant, cost effective, reliable and have the required strength for the well conditions. As these conditions become more severe, material selection changes from carbon steels for sweet wells to duplex (austenitic-ferritic) stainless steels and nickel alloys such as Incoloy® alloys 825 and 925, Inconel®alloys 725HS and 725.
Description. INCOLOY ® 800H / 800HT ®. ASTM B 409, B 408, B 407, B 564 UNS Number N08810/N08811 / N08800. Incoloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure.
Incoloy 825-N08825-2.4858 NiWire Industries Co., Ltd.Incoloy 825 is a nickel-iron-chromium super alloy with addition of molybdenum and copper, resisting wide range of corrosive environments and intergranular sensitization. Incoloy 825 has exceptional resistance to seawater and to reducing chemicals, such as sulfuric and phosphoric acids.
Incoloy Alloy 825 Nickel Alloy Supplier Nickel Alloy INCOLOY alloy 825 (UNS N08825, W.Nr. 2.4858) is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. The nickel content is sufficient for resistance to chloride-ion stress-corrosion cracking.
Nickel Alloy 825 is able to resist stress corrosion cracking and localized corrosion attacks such as intergranular corrosion, pitting corrosion and crevice corrosion cracking. The mechanical properties of the alloy ensure excellent performance under severe conditions at both extremely low cryogenic and moderate high temperatures of up to 1000°C.Ultra range 904L alloy 825 Outokumpu Stainless Steel Outokumpu Ultra range contains corrosion resistant stainless steel products for extremely corrosive environments:904L, 400, alloy. 825, 200, 100.
