Description

625 INCONEL PLATES When it comes to nickel content, Inconel 625® falls between the 330 and 600 alloys at 58% minimum nickel. At 20-23%, chromium is the next most abundant element in this alloy. The addition of columbium and molybdenum adds to the alloy’s performance at various temperatures—which is why Inconel 600® is noted for having superb strength and toughness in temperatures ranging from -32°F (0°C) to 2,000°F (1,093°C). The alloy is also noted for having a particularly high creep rupture strength, fatigue resistance, and chloride pitting/crevice corrosion resistance. Meanwhile, the metal is remarkably easy to weld compared to other Inconel® alloys. The recommended uses of this metal include jet engine exhausts, flare stacks, seawater equipment, and chemical plant equipment because of its high chemical and temperature resistance qualities. 625’s resistance to oxalic acid is particularly high compared to other materials—in a corrosion test by Rolled Alloys, the material experienced only 6.0 mils/year of corrosion in a 10% boiling oxalic acid solution. For comparison, 316L stainless steel experienced 44.9 mils/year of corrosion in the same solution. However, its sulfuric acid resistance was less impressive, experiencing 37 mils/year of corrosion in a 10% concentration bath. 625 Inconel Plate Chemical Composition Chromium :- 20% To 23% Nickel :- 58% To Balance Molybdenum :- 8% To 10% Cobalt :- 1% Max Columbium + Tantalum :- 3.15 % TO 4.15% Carbon :- 0.10 % Max Titanium :- 0.40% Max Aluminium :- 0.40% Max
