Stainless Steel 1.4588 vs 1.4848
Stainless Steel · grade comparison
Stainless Steel 1.4588 and 1.4848 are both stainless steel grades. 1.4588 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 280 MPa (40.6 ksi) for 1.4848, about 7% more; tensile strength follows at 585 MPa (84.8 ksi) vs 530 MPa (76.9 ksi). 1.4588 is the more ductile: elongation 45% versus 14% for 1.4848, and 1.4848 is harder (190 HB vs 170 HB). 1.4848 is lighter (7.75 g/cm³ vs 8 g/cm³ for 1.4588) and 1.4588 is stiffer (195 GPa vs 185 GPa). On the shop floor, 1.4588 welds better (good vs fair) and 1.4848 sits in a lower cost tier (premium, $$$) than 1.4588 (high, $$$$).
1.4588Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4848Choose it when weight is the constraint, or when the part sees heat.
1.4588 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.
