Stainless Steel 416 vs XM-32

Stainless Steel · grade comparison

Stainless Steel 416 and XM-32 are both stainless steel grades. XM-32 is the stronger of the two: yield strength 745 MPa (108 ksi) against 275 MPa (39.9 ksi) for 416, about 171% more; tensile strength follows at 965 MPa (140 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 18% for XM-32, and XM-32 is harder (285 HB vs 155 HB). 416 runs hotter in service (650°C vs 425°C continuous) and 416 conducts heat better (24.9 W/m·K vs 18 W/m·K). On the shop floor, 416 machines more easily (very good vs fair), XM-32 welds better (good vs poor), and 416 sits in a lower cost tier (premium, $$$) than XM-32 (high, $$$$).

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

XM-32Choose it when strength drives the design, or when it will be welded.
