Nickel Alloy Hastelloy C-22 CAST-CX2MW vs Hastelloy C-22-CD

Nickel Alloy · Hastelloy C-22 temper comparison

Hastelloy C-22 CAST-CX2MW and Hastelloy C-22-CD are two conditions of the same nickel alloy grade, Hastelloy C-22: CAST-CX2MW (cast equivalent (ASTM A494 CX-2MW), solution annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Hastelloy C-22-CD is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 320 MPa (46.4 ksi) for Hastelloy C-22 CAST-CX2MW, about 103% more; tensile strength follows at 950 MPa (138 ksi) vs 580 MPa (84.1 ksi). Hastelloy C-22-CD is the more ductile: elongation 32% versus 25% for Hastelloy C-22 CAST-CX2MW, and Hastelloy C-22-CD is harder (250 HB vs 190 HB). Hastelloy C-22 CAST-CX2MW runs hotter in service (1,000°C vs 480°C continuous).

Hastelloy C-22 CAST-CX2MW vs Hastelloy C-22-CD — frequently asked

Is Hastelloy C-22-CD stronger than Hastelloy C-22 CAST-CX2MW?

Yes. Hastelloy C-22-CD has a typical yield strength of 650 MPa (94.3 ksi) against 320 MPa (46.4 ksi) for Hastelloy C-22 CAST-CX2MW — about 103% more. Tensile strength is 950 MPa (138 ksi) vs 580 MPa (84.1 ksi).

Which condition does FabDigit quote by default, CAST-CX2MW or CD?

SA is the default Hastelloy C-22 condition in the FabDigit quote flow (neither CAST-CX2MW nor CD). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, Hastelloy C-22 CAST-CX2MW or Hastelloy C-22-CD?

Hastelloy C-22-CD, by a small margin. Both rate poor for machinability — 24/100 against 18/100 for Hastelloy C-22 CAST-CX2MW; for welding the order is Hastelloy C-22-CD first (very good, 78/100) then Hastelloy C-22 CAST-CX2MW (very good, 70/100).
