Nickel Alloy Hastelloy X As Printed vs Hastelloy X Cold Worked

Nickel Alloy · Hastelloy X temper comparison

Hastelloy X As Printed and Hastelloy X Cold Worked are two conditions of the same nickel alloy grade, Hastelloy X: As Printed (as built (as printed)) versus Cold Worked. The chemistry is identical, so every difference below comes from the condition. Hastelloy X Cold Worked is the stronger of the two: yield strength 800 MPa (116 ksi) against 640 MPa (92.8 ksi) for Hastelloy X As Printed, about 25% more; tensile strength follows at 1,000 MPa (145 ksi) vs 800 MPa (116 ksi). In exchange, Hastelloy X As Printed is the more ductile: elongation 25% versus 12% for Hastelloy X Cold Worked, and Hastelloy X Cold Worked is harder (293 HB vs 195 HB). Hastelloy X Cold Worked is stiffer (206 GPa vs 190 GPa) and Hastelloy X As Printed runs hotter in service (700°C vs 550°C continuous). On the shop floor, Hastelloy X As Printed welds better (excellent vs very good).
