Stainless Steel 1.3967 vs 1.4837
Stainless Steel · grade comparison
Stainless Steel 1.3967 and 1.4837 are both stainless steel grades. 1.3967 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 265 MPa (38.4 ksi) for 1.4837, about 43% more; tensile strength follows at 690 MPa (100 ksi) vs 520 MPa (75.4 ksi). 1.3967 is the more ductile: elongation 32% versus 12% for 1.4837, and 1.3967 is harder (220 HB vs 190 HB). 1.3967 is stiffer (196 GPa vs 185 GPa) and 1.4837 runs hotter in service (1,050°C vs 550°C continuous). On the shop floor, 1.3967 welds better (good vs fair) and 1.4837 sits in a lower cost tier (premium, $$$) than 1.3967 (high, $$$$).
1.3967Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4837Choose it when the part sees heat, or when cost is the deciding factor.
1.3967 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.
