Steel GX3Ni36 vs K93500
Steel · grade comparison
Steel GX3Ni36 and K93500 are both steel grades. K93500 is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 240 MPa (34.8 ksi) for GX3Ni36, about 17% more; tensile strength follows at 490 MPa (71.1 ksi) vs 450 MPa (65.3 ksi). K93500 is the more ductile: elongation 40% versus 25% for GX3Ni36, and K93500 is harder (140 HB vs 130 HB). On the shop floor, K93500 welds better (very good vs good).
K93500Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
GX3Ni36 vs K93500: 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 vs K93500 — frequently asked
Is K93500 stronger than GX3Ni36?
Yes. K93500 has a typical yield strength of 280 MPa (40.6 ksi) against 240 MPa (34.8 ksi) for GX3Ni36 — about 17% more. Tensile strength is 490 MPa (71.1 ksi) vs 450 MPa (65.3 ksi).
Which is cheaper, GX3Ni36 or K93500?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, GX3Ni36 or K93500?
K93500. Its weldability rates very good (70/100) against good (58/100) for GX3Ni36.
