Stainless Steel S44800 Annealed vs S44800 Cold Worked
Stainless Steel · S44800 temper comparison
S44800 Annealed and S44800 Cold Worked are two conditions of the same stainless steel grade, S44800: Annealed versus Cold Worked. The chemistry is identical, so every difference below comes from the condition. S44800 Cold Worked is the stronger of the two: yield strength 700 MPa (102 ksi) against 480 MPa (69.6 ksi) for S44800 Annealed, about 46% more; tensile strength follows at 800 MPa (116 ksi) vs 620 MPa (89.9 ksi). In exchange, S44800 Annealed is the more ductile: elongation 25% versus 6% for S44800 Cold Worked, and S44800 Cold Worked is harder (270 HB vs 210 HB). S44800 Annealed runs hotter in service (300°C vs 250°C continuous). On the shop floor, S44800 Annealed welds better (good vs fair).
S44800 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S44800 Cold WorkedChoose it when strength drives the design.
S44800 Annealed vs S44800 Cold Worked: 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.
