Stainless Steel 1.4807 vs 1.4837
Stainless Steel · grade comparison
Stainless Steel 1.4807 and 1.4837 are both stainless steel grades. 1.4837 is the stronger of the two: yield strength 265 MPa (38.4 ksi) against 240 MPa (34.8 ksi) for 1.4807, about 10% 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 9% for 1.4807. 1.4837 is stiffer (185 GPa vs 165 GPa) and 1.4837 conducts heat better (14.5 W/m·K vs 13 W/m·K). On the shop floor, 1.4837 sits in a lower cost tier (premium, $$$) than 1.4807 (high, $$$$).
1.4837Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4807 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.
