Steel EN-GJMW-400-5 vs G3500
Steel · grade comparison
Steel EN-GJMW-400-5 and G3500 are both steel grades. EN-GJMW-400-5 is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 180 MPa (26.1 ksi) for G3500, about 33% more; tensile strength follows at 430 MPa (62.4 ksi) vs 250 MPa (36.3 ksi). EN-GJMW-400-5 is the more ductile: elongation 7% versus 0.5% for G3500, and G3500 is harder (225 HB vs 195 HB). EN-GJMW-400-5 is stiffer (175 GPa vs 110 GPa) and G3500 runs hotter in service (400°C vs 350°C continuous). On the shop floor, G3500 machines more easily (very good vs good) and EN-GJMW-400-5 welds better (good vs poor).
EN-GJMW-400-5Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
G3500Choose it when the part sees heat, or when the part is machined in volume.
EN-GJMW-400-5 vs G3500: 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.

EN-GJMW-400-5 vs G3500 — frequently asked
Is EN-GJMW-400-5 stronger than G3500?
Yes. EN-GJMW-400-5 has a typical yield strength of 240 MPa (34.8 ksi) against 180 MPa (26.1 ksi) for G3500 — about 33% more. Tensile strength is 430 MPa (62.4 ksi) vs 250 MPa (36.3 ksi).
Which is cheaper, EN-GJMW-400-5 or G3500?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, EN-GJMW-400-5 or G3500?
G3500. Its machinability rates very good (78/100) against good (68/100) for EN-GJMW-400-5; for welding the order is EN-GJMW-400-5 first (good, 60/100) then G3500 (poor, 25/100).
