Stainless Steel 1.4412 vs 1.4837
Stainless Steel · grade comparison
Stainless Steel 1.4412 and 1.4837 are both stainless steel grades. Both yield at about 260 MPa — strength does not separate them. 1.4412 is the more ductile: elongation 38% versus 12% for 1.4837, and 1.4837 is harder (190 HB vs 160 HB). 1.4837 is lighter (7.7 g/cm³ vs 7.95 g/cm³ for 1.4412) and 1.4412 is stiffer (195 GPa vs 185 GPa). On the shop floor, 1.4412 machines more easily (fair vs poor) and 1.4412 welds better (very good vs fair).
1.4412Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
1.4837Choose it when weight is the constraint, or when the part sees heat.
1.4412 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.

1.4412 vs 1.4837 — frequently asked
What is the difference between 1.4412 and 1.4837?
Stainless Steel 1.4412 and 1.4837 are both stainless steel grades. Both yield at about 260 MPa — strength does not separate them. 1.4412 is the more ductile: elongation 38% versus 12% for 1.4837, and 1.4837 is harder (190 HB vs 160 HB).
Which is cheaper, 1.4412 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, 1.4412 or 1.4837?
1.4412. Its machinability rates fair (38/100) against poor (22/100) for 1.4837; for welding the order is 1.4412 first (very good, 75/100) then 1.4837 (fair, 40/100).
