Nickel Alloy Monel R-405-CD vs Monel R-405-HF

Nickel Alloy · Monel R-405 temper comparison

Monel R-405-CD and Monel R-405-HF are two conditions of the same nickel alloy grade, Monel R-405: CD (cold drawn) versus HF (hot Finished). The chemistry is identical, so every difference below comes from the condition. Monel R-405-CD is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 290 MPa (42.1 ksi) for Monel R-405-HF, about 55% more; tensile strength follows at 620 MPa (89.9 ksi) vs 550 MPa (79.8 ksi). In exchange, Monel R-405-HF is the more ductile: elongation 35% versus 22% for Monel R-405-CD, and Monel R-405-CD is harder (165 HB vs 140 HB).

Monel R-405-CDChoose it when strength drives the design.

Monel R-405-HFChoose it when the part is bent, formed or impact-loaded.
