Stainless Steel 416 vs X47Cr14

Stainless Steel · grade comparison

Stainless Steel 416 and X47Cr14 are both stainless steel grades. X47Cr14 is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 275 MPa (39.9 ksi) for 416, about 64% more; tensile strength follows at 740 MPa (107 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 18% for X47Cr14, and X47Cr14 is harder (225 HB vs 155 HB). X47Cr14 is stiffer (215 GPa vs 200 GPa) and 416 runs hotter in service (650°C vs 400°C continuous). On the shop floor, 416 machines more easily (very good vs fair).

416Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

X47Cr14Choose it when strength drives the design.
