Stainless Steel 2304 vs S32562
Stainless Steel · grade comparison
Stainless Steel 2304 and S32562 are both stainless steel grades. S32562 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 460 MPa (66.7 ksi) for 2304, about 35% more; tensile strength follows at 860 MPa (125 ksi) vs 680 MPa (98.6 ksi). S32562 is harder — 265 HB against 240 HB for 2304 — which matters for wear surfaces and threads. On the shop floor, 2304 machines more easily (fair vs poor), 2304 welds better (very good vs good), and 2304 forms better (good vs fair).
2304Choose it when the part is machined in volume, or when it will be welded.
S32562Choose it when strength drives the design, or when surface hardness matters.
2304 vs S32562: 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.
