Stainless Steel Zeron 100 Annealed vs Zeron 100 Cold Drawn
Stainless Steel · Zeron 100 temper comparison
Zeron 100 Annealed and Zeron 100 Cold Drawn are two conditions of the same stainless steel grade, Zeron 100: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. Zeron 100 Cold Drawn is the stronger of the two: yield strength 790 MPa (115 ksi) against 610 MPa (88.5 ksi) for Zeron 100 Annealed, about 30% more; tensile strength follows at 950 MPa (138 ksi) vs 820 MPa (119 ksi). In exchange, Zeron 100 Annealed is the more ductile: elongation 30% versus 20% for Zeron 100 Cold Drawn, and Zeron 100 Cold Drawn is harder (300 HB vs 248 HB).

Zeron 100 Cold DrawnChoose it when strength drives the design.
Zeron 100 Annealed vs Zeron 100 Cold Drawn: 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.
