HastelloyB3
Material designation: Hastelloy B3
US grade: UNS N10675
I. Overview of Hastelloy B3(N10675):
Hastelloy B3（N10675） is nickel-based superalloy which contain Nickel,molybdenum, cobalt and other elements and its nickel content is about 65 %.Hastelloy B3 (N10675) is a new material improved on the basis of Hastelloy B2,which improves the thermal stability of the material, thereby improving thecorrosion resistance, and improving the hot forming and cold formingproperties. In recent years, it has been increasingly used in the production ofchemical equipment.

III. Features:
Hastelloy B3 (N10675) has mechanical propertiesin the solid solution state: As heating temperature increases, its tensilestrength, yield strength, and elastic modulus decrease, while elongation,thermal expansion coefficient, thermal conductivity, and specific heat increaseslightly High; with the increase of cold deformation rate, its hardness,tensile strength and yield strength increase, elongation decreases.
IV. Specifications and Ex-factory status:
1. Classification: We can supply in form ofHastelloy B3（N10675）seamless pipes, steel plates, roundsteel, forgings, flanges, rings, welded pipes, steel strips, wire andsupporting welding materials.
2. Ex-factory status: Seamless Tube: solidsolution + acid white, length can be fixed; Plate: solid solution, pickling,trimming; Welded Tube: solid solution acid white + RT% flaw detection; Forging:annealing + turning; the bar is delivered in the state of forging, surfacepolishing or lapping; the strip is delivered after cold rolling, solid solutionsoftening, and descaling; the wire is solid-dissolved and pickled in a disc orstraight strip, solid solution straight polished.
