Stainless Steel ZG1Cr18Ni12Mo2Ti CENT-ST vs ZG1Cr18Ni12Mo2Ti-ST
Stainless Steel · ZG1Cr18Ni12Mo2Ti temper comparison
ZG1Cr18Ni12Mo2Ti CENT-ST and ZG1Cr18Ni12Mo2Ti-ST are two conditions of the same stainless steel grade, ZG1Cr18Ni12Mo2Ti: CENT-ST (centrifugally cast, solution treated) versus ST (solution annealed). The chemistry is identical, so every difference below comes from the condition. ZG1Cr18Ni12Mo2Ti CENT-ST is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 245 MPa (35.5 ksi) for ZG1Cr18Ni12Mo2Ti-ST, about 6% more; tensile strength follows at 550 MPa (79.8 ksi) vs 520 MPa (75.4 ksi).

ZG1Cr18Ni12Mo2Ti CENT-ST vs ZG1Cr18Ni12Mo2Ti-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.
