Stainless Steel ZG0Cr18Ni12Mo2Ti-F vs ZG0Cr18Ni12Mo2Ti-ST
Stainless Steel · ZG0Cr18Ni12Mo2Ti temper comparison
ZG0Cr18Ni12Mo2Ti-F and ZG0Cr18Ni12Mo2Ti-ST are two conditions of the same stainless steel grade, ZG0Cr18Ni12Mo2Ti: F (as fabricated) versus ST (solution annealed). The chemistry is identical, so every difference below comes from the condition. ZG0Cr18Ni12Mo2Ti-ST is the stronger of the two: tensile strength 520 MPa (75.4 ksi) against 480 MPa (69.6 ksi) for ZG0Cr18Ni12Mo2Ti-F, about 8% more. ZG0Cr18Ni12Mo2Ti-ST is the more ductile: elongation 40% versus 25% for ZG0Cr18Ni12Mo2Ti-F, and ZG0Cr18Ni12Mo2Ti-F is harder (163 HB vs 150 HB).
ZG0Cr18Ni12Mo2Ti-STChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
ZG0Cr18Ni12Mo2Ti-F vs ZG0Cr18Ni12Mo2Ti-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.
