Stainless Steel 1.4848 vs HT
Stainless Steel · grade comparison
Stainless Steel 1.4848 and HT are both stainless steel grades. 1.4848 is the stronger of the two: tensile strength 530 MPa (76.9 ksi) against 485 MPa (70.3 ksi) for HT, about 9% more. 1.4848 is the more ductile: elongation 14% versus 10% for HT, and 1.4848 is harder (190 HB vs 180 HB). 1.4848 is stiffer (185 GPa vs 175 GPa) and 1.4848 conducts heat better (14 W/m·K vs 12.5 W/m·K). On the shop floor, 1.4848 welds better (45 vs 35 out of 100) and 1.4848 sits in a lower cost tier (premium, $$$) than HT (high, $$$$).
1.4848Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4848 vs HT: 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.
