Stainless Steel 1.4806 vs 1.4837
Stainless Steel · grade comparison
Stainless Steel 1.4806 and 1.4837 are both stainless steel grades. 1.4837 is the stronger of the two: yield strength 265 MPa (38.4 ksi) against 250 MPa (36.3 ksi) for 1.4806, about 6% more; tensile strength follows at 520 MPa (75.4 ksi) vs 470 MPa (68.2 ksi). 1.4837 is the more ductile: elongation 12% versus 10% for 1.4806, and 1.4837 is harder (190 HB vs 180 HB). 1.4837 is lighter (7.7 g/cm³ vs 7.95 g/cm³ for 1.4806) and 1.4837 is stiffer (185 GPa vs 168 GPa). On the shop floor, 1.4837 sits in a lower cost tier (premium, $$$) than 1.4806 (high, $$$$).
1.4837Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4806 vs 1.4837: 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.
