Stainless Steel 1.4825 vs 1.4837
Stainless Steel · grade comparison
Stainless Steel 1.4825 and 1.4837 are both stainless steel grades. Both yield at about 260 MPa — strength does not separate them. 1.4825 is the more ductile: elongation 18% versus 12% for 1.4837, and 1.4837 is harder (190 HB vs 175 HB). 1.4837 runs hotter in service (1,050°C vs 900°C continuous) and 1.4825 conducts electricity better (2.2 % IACS vs 1.9 % IACS). On the shop floor, 1.4825 machines more easily (32 vs 22 out of 100).
1.4825Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
1.4837Choose it when the part sees heat.
1.4825 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.

1.4825 vs 1.4837 — frequently asked
What is the difference between 1.4825 and 1.4837?
Stainless Steel 1.4825 and 1.4837 are both stainless steel grades. Both yield at about 260 MPa — strength does not separate them. 1.4825 is the more ductile: elongation 18% versus 12% for 1.4837, and 1.4837 is harder (190 HB vs 175 HB).
Which is cheaper, 1.4825 or 1.4837?
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 is easier to machine, 1.4825 or 1.4837?
1.4825, by a small margin. Both rate poor for machinability — 32/100 against 22/100 for 1.4837; for welding the order is 1.4825 first (fair, 45/100) then 1.4837 (fair, 40/100).
