Steel A220 M5003 vs EN-GJMW-400-5
Steel · grade comparison
Steel A220 M5003 and EN-GJMW-400-5 are both steel grades. A220 M5003 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 240 MPa (34.8 ksi) for EN-GJMW-400-5, about 58% more; tensile strength follows at 550 MPa (79.8 ksi) vs 430 MPa (62.4 ksi). In exchange, EN-GJMW-400-5 is the more ductile: elongation 7% versus 4% for A220 M5003. A220 M5003 runs hotter in service (400°C vs 350°C continuous) and A220 M5003 conducts electricity better (5.7 % IACS vs 5 % IACS). On the shop floor, EN-GJMW-400-5 welds better (good vs poor) and EN-GJMW-400-5 sits in a lower cost tier (budget, $) than A220 M5003 (standard, $$).
A220 M5003Choose it when strength drives the design, or when the part sees heat.
EN-GJMW-400-5Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
A220 M5003 vs EN-GJMW-400-5: 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.
