Stainless Steel Custom 465 Condition A vs Custom 465-H1100
Stainless Steel · Custom 465 temper comparison
Custom 465 Condition A and Custom 465-H1100 are two conditions of the same stainless steel grade, Custom 465: Condition A (solution annealed) versus H1100 (aged 593 °C (1100 °F) for 4 h). The chemistry is identical, so every difference below comes from the condition. Custom 465-H1100 is the stronger of the two: yield strength 1,310 MPa (190 ksi) against 795 MPa (115 ksi) for Custom 465 Condition A, about 65% more; tensile strength follows at 1,400 MPa (203 ksi) vs 1,000 MPa (145 ksi). Custom 465-H1100 is harder — 43 HRC against 30 HRC for Custom 465 Condition A — which matters for wear surfaces and threads. On the shop floor, Custom 465 Condition A forms better (fair vs poor).
Custom 465-H1100Choose it when strength drives the design, or when surface hardness matters.
Custom 465 Condition A vs Custom 465-H1100: 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.
