Stainless Steel 446 Cold Drawn vs 446 Hot Rolled
Stainless Steel · 446 temper comparison
446 Cold Drawn and 446 Hot Rolled are two conditions of the same stainless steel grade, 446: Cold Drawn versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 446 Cold Drawn is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 380 MPa (55.1 ksi) for 446 Hot Rolled, about 26% more; tensile strength follows at 620 MPa (89.9 ksi) vs 570 MPa (82.7 ksi). In exchange, 446 Hot Rolled is the more ductile: elongation 20% versus 15% for 446 Cold Drawn, and 446 Cold Drawn is harder (210 HB vs 190 HB).
446 Cold DrawnChoose it when strength drives the design.
446 Hot RolledChoose it when the part is bent, formed or impact-loaded.
446 Cold Drawn vs 446 Hot Rolled: 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.

446 Cold Drawn vs 446 Hot Rolled — frequently asked
Is 446 Cold Drawn stronger than 446 Hot Rolled?
Yes. 446 Cold Drawn has a typical yield strength of 480 MPa (69.6 ksi) against 380 MPa (55.1 ksi) for 446 Hot Rolled — about 26% more. Tensile strength is 620 MPa (89.9 ksi) vs 570 MPa (82.7 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Hot Rolled?
Annealed is the default 446 condition in the FabDigit quote flow (neither Cold Drawn nor Hot Rolled). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 446 Cold Drawn or 446 Hot Rolled?
446 Cold Drawn, by a small margin. Both rate fair for machinability — 50/100 against 43/100 for 446 Hot Rolled.
