Stainless Steel S44635 Annealed vs S44635 Cold Worked
Stainless Steel · S44635 temper comparison
S44635 Annealed and S44635 Cold Worked are two conditions of the same stainless steel grade, S44635: Annealed versus Cold Worked. The chemistry is identical, so every difference below comes from the condition. S44635 Cold Worked is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 500 MPa (72.5 ksi) for S44635 Annealed, about 30% more; tensile strength follows at 790 MPa (115 ksi) vs 680 MPa (98.6 ksi). In exchange, S44635 Annealed is the more ductile: elongation 27% versus 15% for S44635 Cold Worked, and S44635 Cold Worked is harder (250 HB vs 210 HB).

S44635 Annealed vs S44635 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.
