Stainless Steel 1.4826 vs 1.4837
Stainless Steel · grade comparison
Stainless Steel 1.4826 and 1.4837 are both stainless steel grades. Both yield at about 260 MPa — strength does not separate them. 1.4837 is the more ductile: elongation 12% versus 10% for 1.4826.
1.4837Choose it when the part is bent, formed or impact-loaded.
1.4826 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.
