Stainless Steel 1.4848 vs 10Kh18N9L
Stainless Steel · grade comparison
Stainless Steel 1.4848 and 10Kh18N9L are both stainless steel grades. 1.4848 is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 225 MPa (32.6 ksi) for 10Kh18N9L, about 24% more; tensile strength follows at 530 MPa (76.9 ksi) vs 500 MPa (72.5 ksi). In exchange, 10Kh18N9L is the more ductile: elongation 40% versus 14% for 1.4848, and 1.4848 is harder (190 HB vs 145 HB). 1.4848 runs hotter in service (1,100°C vs 650°C continuous) and 10Kh18N9L conducts electricity better (2.4 % IACS vs 1.9 % IACS). On the shop floor, 10Kh18N9L machines more easily (fair vs poor) and 10Kh18N9L welds better (excellent vs fair).
1.4848Choose it when strength drives the design, or when the part sees heat.
10Kh18N9LChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
1.4848 vs 10Kh18N9L: 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.
