Steel A182 F12 Cl.1 vs AR500
Steel · grade comparison
Steel A182 F12 Cl.1 and AR500 are both steel grades. AR500 is the stronger of the two: yield strength 1,350 MPa (196 ksi) against 265 MPa (38.4 ksi) for A182 F12 Cl.1, about 5.1 times as much; tensile strength follows at 1,650 MPa (239 ksi) vs 460 MPa (66.7 ksi). In exchange, A182 F12 Cl.1 is the more ductile: elongation 30% versus 9% for AR500, and AR500 is harder (500 HB vs 140 HB). A182 F12 Cl.1 runs hotter in service (550°C vs 250°C continuous). On the shop floor, A182 F12 Cl.1 machines more easily (good vs not recommended), A182 F12 Cl.1 welds better (good vs fair), and A182 F12 Cl.1 sits in a lower cost tier (budget, $) than AR500 (high, $$$$).
A182 F12 Cl.1Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
AR500Choose it when strength drives the design.
A182 F12 Cl.1 vs AR500: 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.
