Steel 1008 vs P235TR2
Steel · grade comparison
Steel 1008 and P235TR2 are both steel grades. P235TR2 is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 175 MPa (25.4 ksi) for 1008, about 49% more; tensile strength follows at 420 MPa (60.9 ksi) vs 300 MPa (43.5 ksi). P235TR2 is harder — 125 HB against 86 HB for 1008 — which matters for wear surfaces and threads. 1008 runs hotter in service (425°C vs 300°C continuous) and 1008 conducts heat better (60 W/m·K vs 52 W/m·K). On the shop floor, P235TR2 machines more easily (good vs fair).
1008Choose it when the part sees heat.
P235TR2Choose it when strength drives the design, or when surface hardness matters.
1008 vs P235TR2: 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.

1008 vs P235TR2 — frequently asked
Is P235TR2 stronger than 1008?
Yes. P235TR2 has a typical yield strength of 260 MPa (37.7 ksi) against 175 MPa (25.4 ksi) for 1008 — about 49% more. Tensile strength is 420 MPa (60.9 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, 1008 or P235TR2?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1008 or P235TR2?
P235TR2. Its machinability rates good (60/100) against fair (48/100) for 1008.
