Stainless Steel PH 13-8 Mo Condition A vs PH 13-8 Mo-H1150
Stainless Steel · PH 13-8 Mo temper comparison
PH 13-8 Mo Condition A and PH 13-8 Mo-H1150 are two conditions of the same stainless steel grade, PH 13-8 Mo: Condition A (solution annealed) versus H1150 (overaged 621 °C (1150 °F) for 4 h, maximum toughness). The chemistry is identical, so every difference below comes from the condition. PH 13-8 Mo-H1150 is the stronger of the two: yield strength 965 MPa (140 ksi) against 800 MPa (116 ksi) for PH 13-8 Mo Condition A, about 21% more; tensile strength follows at 1,070 MPa (155 ksi) vs 1,000 MPa (145 ksi). PH 13-8 Mo-H1150 is the more ductile: elongation 18% versus 14% for PH 13-8 Mo Condition A. PH 13-8 Mo-H1150 runs hotter in service (510°C vs 315°C continuous).
PH 13-8 Mo-H1150Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
PH 13-8 Mo Condition A vs PH 13-8 Mo-H1150: 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.

PH 13-8 Mo Condition A vs PH 13-8 Mo-H1150 — frequently asked
Is PH 13-8 Mo-H1150 stronger than PH 13-8 Mo Condition A?
Yes. PH 13-8 Mo-H1150 has a typical yield strength of 965 MPa (140 ksi) against 800 MPa (116 ksi) for PH 13-8 Mo Condition A — about 21% more. Tensile strength is 1,070 MPa (155 ksi) vs 1,000 MPa (145 ksi).
Which condition does FabDigit quote by default, Condition A or H1150?
Condition A is the default PH 13-8 Mo 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.
When should I choose PH 13-8 Mo Condition A over PH 13-8 Mo-H1150?
Pick PH 13-8 Mo-H1150 when strength drives the design, or when the part is bent, formed or impact-loaded.
