Steel A210 vs A369 Grade FPA
Steel · grade comparison
Steel A210 and A369 Grade FPA 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 A369 Grade FPA, about 20% more; tensile strength follows at 470 MPa (68.2 ksi) vs 415 MPa (60.2 ksi). A210 is harder — 130 HB against 120 HB for A369 Grade FPA — which matters for wear surfaces and threads. On the shop floor, A210 sits in a lower cost tier (budget, $) than A369 Grade FPA (standard, $$).
A210Choose it when strength drives the design, or when surface hardness matters.
A210 vs A369 Grade FPA: 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.
