Steel GX3Ni36-A vs GX3Ni36 HIP+A
Steel · GX3Ni36 temper comparison
GX3Ni36-A and GX3Ni36 HIP+A are two conditions of the same steel grade, GX3Ni36: A (solution annealed) versus HIP+A (hot isostatically pressed then annealed). The chemistry is identical, so every difference below comes from the condition. GX3Ni36 HIP+A is the stronger of the two: yield strength 225 MPa (32.6 ksi) against 205 MPa (29.7 ksi) for GX3Ni36-A, about 10% more; tensile strength follows at 470 MPa (68.2 ksi) vs 425 MPa (61.6 ksi). GX3Ni36 HIP+A is the more ductile: elongation 35% versus 30% for GX3Ni36-A.
GX3Ni36 HIP+AChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
GX3Ni36-A vs GX3Ni36 HIP+A: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all 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.

GX3Ni36-A vs GX3Ni36 HIP+A — frequently asked
Is GX3Ni36 HIP+A stronger than GX3Ni36-A?
Yes. GX3Ni36 HIP+A has a typical yield strength of 225 MPa (32.6 ksi) against 205 MPa (29.7 ksi) for GX3Ni36-A — about 10% more. Tensile strength is 470 MPa (68.2 ksi) vs 425 MPa (61.6 ksi).
Which condition does FabDigit quote by default, A or HIP+A?
F is the default GX3Ni36 condition in the FabDigit quote flow (neither A nor HIP+A). 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 GX3Ni36-A over GX3Ni36 HIP+A?
Pick GX3Ni36 HIP+A when strength drives the design, or when the part is bent, formed or impact-loaded.
