Stainless Steel CE30 HOM-SR vs CE30-ST
Stainless Steel · CE30 temper comparison
CE30 HOM-SR and CE30-ST are two conditions of the same stainless steel grade, CE30: HOM-SR (homogenized / stress relieved) versus ST (solution annealed). The chemistry is identical, so every difference below comes from the condition. CE30 HOM-SR is the stronger of the two: yield strength 400 MPa (58 ksi) against 360 MPa (52.2 ksi) for CE30-ST, about 11% more. In exchange, CE30-ST is the more ductile: elongation 22% versus 16% for CE30 HOM-SR, and CE30 HOM-SR is harder (185 HB vs 175 HB).
CE30 HOM-SRChoose it when strength drives the design.
CE30-STChoose it when the part is bent, formed or impact-loaded.
CE30 HOM-SR vs CE30-ST: 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.

CE30 HOM-SR vs CE30-ST — frequently asked
Is CE30 HOM-SR stronger than CE30-ST?
Yes. CE30 HOM-SR has a typical yield strength of 400 MPa (58 ksi) against 360 MPa (52.2 ksi) for CE30-ST — about 11% more. Tensile strength is 655 MPa (95 ksi) vs 640 MPa (92.8 ksi).
Which condition does FabDigit quote by default, HOM-SR or ST?
F is the default CE30 condition in the FabDigit quote flow (neither HOM-SR nor ST). 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.
When should I choose CE30 HOM-SR over CE30-ST?
Pick CE30 HOM-SR when strength drives the design. Pick CE30-ST when the part is bent, formed or impact-loaded.
