Stainless Steel 1.4592-1/4 Hard vs 1.4592 Annealed
Stainless Steel · 1.4592 temper comparison
1.4592-1/4 Hard and 1.4592 Annealed are two conditions of the same stainless steel grade, 1.4592: 1/4 Hard (quarter hard) versus Annealed. The chemistry is identical, so every difference below comes from the condition. 1.4592-1/4 Hard is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 480 MPa (69.6 ksi) for 1.4592 Annealed, about 29% more; tensile strength follows at 720 MPa (104 ksi) vs 600 MPa (87 ksi). In exchange, 1.4592 Annealed is the more ductile: elongation 25% versus 12% for 1.4592-1/4 Hard, and 1.4592-1/4 Hard is harder (225 HB vs 185 HB). 1.4592 Annealed runs hotter in service (300°C vs 250°C continuous).

1.4592-1/4 Hard vs 1.4592 Annealed: 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.

1.4592-1/4 Hard vs 1.4592 Annealed — frequently asked
Is 1.4592-1/4 Hard stronger than 1.4592 Annealed?
Yes. 1.4592-1/4 Hard has a typical yield strength of 620 MPa (89.9 ksi) against 480 MPa (69.6 ksi) for 1.4592 Annealed — about 29% more. Tensile strength is 720 MPa (104 ksi) vs 600 MPa (87 ksi).
Which condition does FabDigit quote by default, 1/4 Hard or Annealed?
Annealed is the default 1.4592 condition in the FabDigit quote flow. 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, 1.4592-1/4 Hard or 1.4592 Annealed?
1.4592 Annealed, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for 1.4592-1/4 Hard; for welding the order is 1.4592 Annealed first (good, 60/100) then 1.4592-1/4 Hard (good, 55/100).
