Stainless Steel CX As Printed vs CX Hardened & Tempered

Stainless Steel · CX temper comparison

CX As Printed and CX Hardened & Tempered are two conditions of the same stainless steel grade, CX: As Printed (as built (as printed)) versus Hardened & Tempered (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. CX Hardened & Tempered is the stronger of the two: yield strength 1,550 MPa (225 ksi) against 900 MPa (131 ksi) for CX As Printed, about 72% more; tensile strength follows at 1,670 MPa (242 ksi) vs 1,100 MPa (160 ksi). In exchange, CX As Printed is the more ductile: elongation 11% versus 5% for CX Hardened & Tempered, and CX Hardened & Tempered is harder (50 HRC vs 33 HRC). CX Hardened & Tempered is stiffer (200 GPa vs 185 GPa) and CX Hardened & Tempered runs hotter in service (400°C vs 350°C continuous). On the shop floor, CX As Printed machines more easily (fair vs poor).

CX As PrintedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

CX Hardened & TemperedChoose it when strength drives the design, or when the part sees heat.
