What is Inconel 625 Plate?
While the yield strength of Werkstoff Nr. 2.4856 is 448 Mpa, its Rockwell hardness is B94 and its melting point is between 1290°C to 1350°C. Both specifications covered by the SAE i.e. AMS 5869 and AMS5599 take into consideration this nickel based UNS N06625.
Inconel 625 Plate
Nickel Alloy 625 Sheet
UNS N06625 Coil
The chemistry of this solution heat treated alloy contains 62% Nickel with significant additions of remaining elements such as 21.5% Chromium, 9% Molybdenum as well as 3.7% niobium. While the primary alloyant nickel makes it possible to be used at elevated temperatures, the addition of chromium content in the alloy is what prevents oxidation corrosion. This is seen especially when Alloy 625 has been exposed to air around seawater, by forming a passivated oxide layer on the surface of the plate. Moreover, it is this chemistry that makes the alloy well suited to be used in seawater, as it has immunity against getting attacked in such conditions.
What is ASTM B443 UNS N06625 Sheet?
Covering Inconel 625, the plates, sheets, and strips produced according to ASTM B443 can be produced in two conditions labelled as grade 1 i.e. annealed and grade 2 i.e. solution annealed. Following which these components are to be sampled and tested for their conformance to the dimensions, mechanical and chemical requirement presented here. To avail of the most reasonable price for good quality UNS No 6625 Plates, Sheet, Coil and Strips.
