Stainless Steel CX-HIP vs CX Stress Relieved
Stainless Steel · CX temper comparison
CX-HIP and CX Stress Relieved are two conditions of the same stainless steel grade, CX: HIP (hot isostatic pressed) 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 790 MPa (115 ksi) for CX-HIP, about 65% more; tensile strength follows at 1,450 MPa (210 ksi) vs 1,030 MPa (149 ksi). In exchange, CX-HIP is the more ductile: elongation 16% versus 8% for CX Stress Relieved, and CX Stress Relieved is harder (425 HB vs 320 HB). CX Stress Relieved runs hotter in service (400°C vs 350°C continuous). On the shop floor, CX-HIP machines more easily (fair vs poor) and CX-HIP welds better (very good vs good).
CX-HIPChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
CX Stress RelievedChoose it when strength drives the design, or when the part sees heat.
CX-HIP 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.

CX-HIP vs CX Stress Relieved — frequently asked
Is CX Stress Relieved stronger than CX-HIP?
Yes. CX Stress Relieved has a typical yield strength of 1,300 MPa (189 ksi) against 790 MPa (115 ksi) for CX-HIP — about 65% more. Tensile strength is 1,450 MPa (210 ksi) vs 1,030 MPa (149 ksi).
Which condition does FabDigit quote by default, HIP or Stress Relieved?
As Printed is the default CX condition in the FabDigit quote flow (neither HIP nor Stress Relieved). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, CX-HIP or CX Stress Relieved?
CX-HIP. Its machinability rates fair (42/100) against poor (30/100) for CX Stress Relieved; for welding the order is CX-HIP first (very good, 72/100) then CX Stress Relieved (good, 55/100).
