Stainless Steel 1.4825 vs 1.4849
Stainless Steel · grade comparison
Stainless Steel 1.4825 and 1.4849 are both stainless steel grades. 1.4825 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. 1.4825 is the more ductile: elongation 18% versus 10% for 1.4849. 1.4825 is stiffer (185 GPa vs 170 GPa) and 1.4849 runs hotter in service (1,050°C vs 900°C continuous). On the shop floor, 1.4825 machines more easily (32 vs 20 out of 100), 1.4849 welds better (good vs fair), and 1.4825 sits in a lower cost tier (premium, $$$) than 1.4849 (high, $$$$).
1.4825Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4849Choose it when the part sees heat, or when it will be welded.
1.4825 vs 1.4849: 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.
