Stainless Steel Zeron 100 Cold Drawn vs Zeron 100 Hot Finished
Stainless Steel · Zeron 100 temper comparison
Zeron 100 Cold Drawn and Zeron 100 Hot Finished are two conditions of the same stainless steel grade, Zeron 100: Cold Drawn versus Hot Finished (hot rolled/hot worked then solution annealed and quenched). 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 600 MPa (87 ksi) for Zeron 100 Hot Finished, about 32% more; tensile strength follows at 950 MPa (138 ksi) vs 800 MPa (116 ksi). In exchange, Zeron 100 Hot Finished is the more ductile: elongation 28% versus 20% for Zeron 100 Cold Drawn, and Zeron 100 Cold Drawn is harder (300 HB vs 245 HB).
Zeron 100 Cold DrawnChoose it when strength drives the design.
Zeron 100 Hot FinishedChoose it when the part is bent, formed or impact-loaded.
Zeron 100 Cold Drawn vs Zeron 100 Hot Finished: 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.
