Stainless Steel 1.4848 vs HP
Stainless Steel · grade comparison
Stainless Steel 1.4848 and HP are both stainless steel grades. Both yield at about 280 MPa — strength does not separate them. 1.4848 is the more ductile: elongation 14% versus 10% for HP. 1.4848 conducts heat better (14 W/m·K vs 12.5 W/m·K). On the shop floor, 1.4848 sits in a lower cost tier (premium, $$$) than HP (high, $$$$).

1.4848 vs HP: 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.
