Stainless Steel 1.4552 vs 1.4848
Stainless Steel · grade comparison
Stainless Steel 1.4552 and 1.4848 are both stainless steel grades. 1.4848 is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 250 MPa (36.3 ksi) for 1.4552, about 12% more. In exchange, 1.4552 is the more ductile: elongation 39% versus 14% for 1.4848, and 1.4848 is harder (190 HB vs 149 HB). 1.4848 runs hotter in service (1,100°C vs 815°C continuous) and 1.4552 conducts heat better (16.2 W/m·K vs 14 W/m·K). On the shop floor, 1.4552 machines more easily (fair vs poor) and 1.4552 welds better (very good vs fair).
1.4552Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
1.4848Choose it when strength drives the design, or when the part sees heat.
1.4552 vs 1.4848: 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.

1.4552 vs 1.4848 — frequently asked
Is 1.4848 stronger than 1.4552?
Yes. 1.4848 has a typical yield strength of 280 MPa (40.6 ksi) against 250 MPa (36.3 ksi) for 1.4552 — about 12% more. Tensile strength is 530 MPa (76.9 ksi) vs 530 MPa (76.9 ksi).
Which is cheaper, 1.4552 or 1.4848?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1.4552 or 1.4848?
1.4552. Its machinability rates fair (35/100) against poor (25/100) for 1.4848; for welding the order is 1.4552 first (very good, 78/100) then 1.4848 (fair, 45/100).
