Nickel Alloy Hastelloy N-AW vs Hastelloy N Cast

Nickel Alloy · Hastelloy N temper comparison

Hastelloy N-AW and Hastelloy N Cast are two conditions of the same nickel alloy grade, Hastelloy N: AW (as-welded deposit) versus Cast (as cast). The chemistry is identical, so every difference below comes from the condition. Hastelloy N-AW is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 300 MPa (43.5 ksi) for Hastelloy N Cast, about 40% more; tensile strength follows at 760 MPa (110 ksi) vs 550 MPa (79.8 ksi). Hastelloy N-AW is the more ductile: elongation 33% versus 15% for Hastelloy N Cast. On the shop floor, Hastelloy N-AW welds better (very good vs good).
