Stainless Steel 1.4848 vs HF
Stainless Steel · grade comparison
Stainless Steel 1.4848 and HF are both stainless steel grades. HF is the stronger of the two: yield strength 310 MPa (45 ksi) against 280 MPa (40.6 ksi) for 1.4848, about 11% more; tensile strength follows at 620 MPa (89.9 ksi) vs 530 MPa (76.9 ksi). HF is the more ductile: elongation 38% versus 14% for 1.4848, and 1.4848 is harder (190 HB vs 165 HB). 1.4848 runs hotter in service (1,100°C vs 870°C continuous) and HF conducts electricity better (2.2 % IACS vs 1.9 % IACS).
1.4848Choose it when the part sees heat.
HFChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4848 vs HF: 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.

1.4848 vs HF — frequently asked
Is HF stronger than 1.4848?
Yes. HF has a typical yield strength of 310 MPa (45 ksi) against 280 MPa (40.6 ksi) for 1.4848 — about 11% more. Tensile strength is 620 MPa (89.9 ksi) vs 530 MPa (76.9 ksi).
Which is cheaper, 1.4848 or HF?
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, 1.4848 or HF?
HF, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for 1.4848; for welding the order is HF first (fair, 50/100) then 1.4848 (fair, 45/100).
