Stainless Steel 1.4527 vs 1.4849
Stainless Steel · grade comparison
Stainless Steel 1.4527 and 1.4849 are both stainless steel grades. 1.4849 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 215 MPa (31.2 ksi) for 1.4527, about 16% more. In exchange, 1.4527 is the more ductile: elongation 45% versus 10% for 1.4849, and 1.4849 is harder (180 HB vs 150 HB). 1.4527 is stiffer (193 GPa vs 170 GPa) and 1.4849 runs hotter in service (1,050°C vs 425°C continuous). On the shop floor, 1.4527 machines more easily (32 vs 20 out of 100) and 1.4527 welds better (very good vs good).
1.4527Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
1.4849Choose it when strength drives the design, or when the part sees heat.
1.4527 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.

1.4527 vs 1.4849 — frequently asked
Is 1.4849 stronger than 1.4527?
Yes. 1.4849 has a typical yield strength of 250 MPa (36.3 ksi) against 215 MPa (31.2 ksi) for 1.4527 — about 16% more. Tensile strength is 490 MPa (71.1 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, 1.4527 or 1.4849?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1.4527 or 1.4849?
1.4527, by a small margin. Both rate poor for machinability — 32/100 against 20/100 for 1.4849; for welding the order is 1.4527 first (very good, 70/100) then 1.4849 (good, 55/100).
