Steel A210 vs A285
Steel · grade comparison
Steel A210 and A285 are both steel grades. A210 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 250 MPa (36.3 ksi) for A285, about 20% more. A210 is the more ductile: elongation 35% versus 30% for A285. On the shop floor, A210 sits in a lower cost tier (budget, $) than A285 (standard, $$).
A210Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
A210 vs A285: 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.

A210 vs A285 — frequently asked
Is A210 stronger than A285?
Yes. A210 has a typical yield strength of 300 MPa (43.5 ksi) against 250 MPa (36.3 ksi) for A285 — about 20% more. Tensile strength is 470 MPa (68.2 ksi) vs 450 MPa (65.3 ksi).
Which is cheaper, A210 or A285?
A210 is the lower-cost material: it sits in the budget tier ($) while A285 is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, A210 or A285?
A285, by a small margin. Both rate good for machinability — 68/100 against 62/100 for A210; for welding the order is A285 first (excellent, 92/100) then A210 (excellent, 85/100).
