Stainless Steel 1.4826 vs 1.4849
Stainless Steel · grade comparison
Stainless Steel 1.4826 and 1.4849 are both stainless steel grades. 1.4826 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. 1.4826 is harder — 190 HB against 180 HB for 1.4849 — which matters for wear surfaces and threads. 1.4826 is stiffer (185 GPa vs 170 GPa) and 1.4826 conducts electricity better (2 % IACS vs 1.7 % IACS). On the shop floor, 1.4849 welds better (good vs fair) and 1.4826 sits in a lower cost tier (premium, $$$) than 1.4849 (high, $$$$).
1.4826Choose it when strength drives the design, or when surface hardness matters.
1.4849Choose it when it will be welded.
1.4826 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.
