Stainless Steel 1.4837 vs 1.4848
Stainless Steel · grade comparison
Stainless Steel 1.4837 and 1.4848 are both stainless steel grades. 1.4848 is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 265 MPa (38.4 ksi) for 1.4837, about 6% more. 1.4848 is the more ductile: elongation 14% versus 12% for 1.4837.
1.4848Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4837 vs 1.4848: 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.

1.4837 vs 1.4848 — frequently asked
Is 1.4848 stronger than 1.4837?
Yes. 1.4848 has a typical yield strength of 280 MPa (40.6 ksi) against 265 MPa (38.4 ksi) for 1.4837 — about 6% more. Tensile strength is 530 MPa (76.9 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 1.4837 or 1.4848?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, 1.4837 or 1.4848?
1.4848. Its weldability rates fair (45/100) against fair (40/100) for 1.4837.
