Steel A285 vs P195TR1
Steel · grade comparison
Steel A285 and P195TR1 are both steel grades. A285 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 230 MPa (33.4 ksi) for P195TR1, about 9% more; tensile strength follows at 450 MPa (65.3 ksi) vs 370 MPa (53.7 ksi). A285 is harder — 130 HB against 110 HB for P195TR1 — which matters for wear surfaces and threads. A285 runs hotter in service (425°C vs 300°C continuous). On the shop floor, P195TR1 sits in a lower cost tier (budget, $) than A285 (standard, $$).
A285Choose it when strength drives the design, or when surface hardness matters.
P195TR1Choose it when cost is the deciding factor.
A285 vs P195TR1: 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.
