Nickel Alloy Haynes 214 vs Inconel 625

Nickel Alloy · grade comparison

Nickel Alloy Haynes 214 and Inconel 625 are both nickel alloy grades. Haynes 214 is the stronger of the two: yield strength 565 MPa (81.9 ksi) against 490 MPa (71.1 ksi) for Inconel 625, about 15% more. In exchange, Inconel 625 is the more ductile: elongation 45% versus 38% for Haynes 214, and Haynes 214 is harder (200 HB vs 190 HB). Haynes 214 is lighter (8.05 g/cm³ vs 8.44 g/cm³ for Inconel 625) and Haynes 214 runs hotter in service (1,200°C vs 650°C continuous). On the shop floor, Inconel 625 welds better (excellent vs good) and Inconel 625 sits in a lower cost tier (premium, $$$) than Haynes 214 (high, $$$$).

Haynes 214Choose it when strength drives the design, or when weight is the constraint.

Inconel 625Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
