Stainless Steel CX As Printed vs CX Stress Relieved
Stainless Steel · CX temper comparison
CX As Printed and CX Stress Relieved are two conditions of the same stainless steel grade, CX: As Printed (as built (as printed)) versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. CX Stress Relieved is the stronger of the two: yield strength 1,300 MPa (189 ksi) against 900 MPa (131 ksi) for CX As Printed, about 44% more; tensile strength follows at 1,450 MPa (210 ksi) vs 1,100 MPa (160 ksi). In exchange, CX As Printed is the more ductile: elongation 11% versus 8% for CX Stress Relieved, and CX Stress Relieved is harder (425 HB vs 310 HB). CX Stress Relieved runs hotter in service (400°C vs 350°C continuous). On the shop floor, CX As Printed welds better (very good vs good).
CX As PrintedChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
CX Stress RelievedChoose it when strength drives the design, or when the part sees heat.
CX As Printed vs CX Stress Relieved: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
