Stainless Steel S28200 1/2H vs S28200 Annealed
Stainless Steel · S28200 temper comparison
S28200 1/2H and S28200 Annealed are two conditions of the same stainless steel grade, S28200: 1/2H (half hard) versus Annealed. The chemistry is identical, so every difference below comes from the condition. S28200 1/2H is the stronger of the two: yield strength 760 MPa (110 ksi) against 448 MPa (65 ksi) for S28200 Annealed, about 70% more; tensile strength follows at 1,030 MPa (149 ksi) vs 760 MPa (110 ksi). In exchange, S28200 Annealed is the more ductile: elongation 50% versus 18% for S28200 1/2H, and S28200 1/2H is harder (310 HB vs 210 HB). S28200 Annealed runs hotter in service (815°C vs 425°C continuous). On the shop floor, S28200 Annealed welds better (good vs fair).

S28200 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S28200 1/2H vs S28200 Annealed: 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.
