Steel GX5NiS36-F vs GX5NiS36-HIP
Steel · GX5NiS36 temper comparison
GX5NiS36-F and GX5NiS36-HIP are two conditions of the same steel grade, GX5NiS36: F (as fabricated) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. Both yield at about 215 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus hot isostatic pressed). GX5NiS36-HIP is the more ductile: elongation 18% versus 10% for GX5NiS36-F.

GX5NiS36-F vs GX5NiS36-HIP: 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.

GX5NiS36-F vs GX5NiS36-HIP — frequently asked
What is the difference between GX5NiS36-F and GX5NiS36-HIP?
GX5NiS36-F and GX5NiS36-HIP are two conditions of the same steel grade, GX5NiS36: F (as fabricated) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. Both yield at about 215 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus hot isostatic pressed).
Which condition does FabDigit quote by default, F or HIP?
SR is the default GX5NiS36 condition in the FabDigit quote flow (neither F nor HIP). 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 welds better, GX5NiS36-F or GX5NiS36-HIP?
GX5NiS36-HIP. Its weldability rates poor (30/100) against poor (22/100) for GX5NiS36-F.
