Stainless Steel 1.4805 vs 1.4837
Stainless Steel · grade comparison
Stainless Steel 1.4805 and 1.4837 are both stainless steel grades. 1.4837 is the stronger of the two: tensile strength 520 MPa (75.4 ksi) against 470 MPa (68.2 ksi) for 1.4805, about 11% more. 1.4837 is harder — 190 HB against 165 HB for 1.4805 — which matters for wear surfaces and threads. 1.4837 conducts heat better (14.5 W/m·K vs 12.5 W/m·K). On the shop floor, 1.4837 sits in a lower cost tier (premium, $$$) than 1.4805 (high, $$$$).
1.4837Choose it when strength drives the design, or when surface hardness matters.
1.4805 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.
