Stainless Steel 13-8 PH Condition A vs 13-8 PH-H1025
Stainless Steel · 13-8 PH temper comparison
13-8 PH Condition A and 13-8 PH-H1025 are two conditions of the same stainless steel grade, 13-8 PH: Condition A (solution annealed) versus H1025 (aged 552 °C (1025 °F) for 4 h). The chemistry is identical, so every difference below comes from the condition. 13-8 PH-H1025 is the stronger of the two: yield strength 1,310 MPa (190 ksi) against 827 MPa (120 ksi) for 13-8 PH Condition A, about 58% more; tensile strength follows at 1,415 MPa (205 ksi) vs 1,000 MPa (145 ksi). 13-8 PH-H1025 is harder — 43 HRC against 33 HRC for 13-8 PH Condition A — which matters for wear surfaces and threads.
13-8 PH-H1025Choose it when strength drives the design, or when surface hardness matters.
13-8 PH Condition A vs 13-8 PH-H1025: 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.

13-8 PH Condition A vs 13-8 PH-H1025 — frequently asked
Is 13-8 PH-H1025 stronger than 13-8 PH Condition A?
Yes. 13-8 PH-H1025 has a typical yield strength of 1,310 MPa (190 ksi) against 827 MPa (120 ksi) for 13-8 PH Condition A — about 58% more. Tensile strength is 1,415 MPa (205 ksi) vs 1,000 MPa (145 ksi).
Which condition does FabDigit quote by default, Condition A or H1025?
Condition A is the default 13-8 PH 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, 13-8 PH Condition A or 13-8 PH-H1025?
13-8 PH Condition A, by a small margin. Both rate poor for machinability — 32/100 against 26/100 for 13-8 PH-H1025.
