Steel A182 F10 vs AR500

Steel · grade comparison

Steel A182 F10 and AR500 are both steel grades. AR500 is the stronger of the two: yield strength 1,350 MPa (196 ksi) against 260 MPa (37.7 ksi) for A182 F10, about 5.2 times as much; tensile strength follows at 1,650 MPa (239 ksi) vs 600 MPa (87 ksi). In exchange, A182 F10 is the more ductile: elongation 45% versus 9% for AR500, and AR500 is harder (500 HB vs 170 HB). A182 F10 runs hotter in service (1,050°C vs 250°C continuous) and AR500 conducts heat better (40 W/m·K vs 14.2 W/m·K). On the shop floor, A182 F10 machines more easily (poor vs not recommended) and A182 F10 welds better (good vs fair).

A182 F10Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

AR500Choose it when strength drives the design.

A182 F10 vs AR500 — frequently asked

Is AR500 stronger than A182 F10?

Yes. AR500 has a typical yield strength of 1,350 MPa (196 ksi) against 260 MPa (37.7 ksi) for A182 F10 — about 5.2 times as much. Tensile strength is 1,650 MPa (239 ksi) vs 600 MPa (87 ksi).

Which is cheaper, A182 F10 or AR500?

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 is easier to machine, A182 F10 or AR500?

A182 F10. Its machinability rates poor (32/100) against not recommended (12/100) for AR500; for welding the order is A182 F10 first (good, 60/100) then AR500 (fair, 45/100).
