Stainless Steel 1.4849 vs ZG1Cr18Ni9
Stainless Steel · grade comparison
Stainless Steel 1.4849 and ZG1Cr18Ni9 are both stainless steel grades. ZG1Cr18Ni9 is the stronger of the two: tensile strength 520 MPa (75.4 ksi) against 490 MPa (71.1 ksi) for 1.4849, about 6% more. ZG1Cr18Ni9 is the more ductile: elongation 55% versus 10% for 1.4849, and 1.4849 is harder (180 HB vs 140 HB). ZG1Cr18Ni9 is stiffer (193 GPa vs 170 GPa) and 1.4849 runs hotter in service (1,050°C vs 760°C continuous). On the shop floor, ZG1Cr18Ni9 machines more easily (fair vs poor), ZG1Cr18Ni9 welds better (excellent vs good), and ZG1Cr18Ni9 sits in a lower cost tier (premium, $$$) than 1.4849 (high, $$$$).

ZG1Cr18Ni9Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4849 vs ZG1Cr18Ni9: 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.
