Stainless Steel ZG0Cr18Ni12Mo2Ti-ST vs ZG0Cr18Ni12Mo2Ti ST-HIP
Stainless Steel · ZG0Cr18Ni12Mo2Ti temper comparison
ZG0Cr18Ni12Mo2Ti-ST and ZG0Cr18Ni12Mo2Ti ST-HIP are two conditions of the same stainless steel grade, ZG0Cr18Ni12Mo2Ti: ST (solution annealed) versus ST-HIP. The chemistry is identical, so every difference below comes from the condition. ZG0Cr18Ni12Mo2Ti ST-HIP is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 235 MPa (34.1 ksi) for ZG0Cr18Ni12Mo2Ti-ST, about 6% more. ZG0Cr18Ni12Mo2Ti ST-HIP is the more ductile: elongation 46% versus 40% for ZG0Cr18Ni12Mo2Ti-ST.
ZG0Cr18Ni12Mo2Ti ST-HIPChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
ZG0Cr18Ni12Mo2Ti-ST vs ZG0Cr18Ni12Mo2Ti ST-HIP: 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.
