Steel S460 Normalized vs S460 TMCP
Steel · S460 temper comparison
S460 Normalized and S460 TMCP are two conditions of the same steel grade, S460: Normalized versus TMCP (thermomechanically controlled processed). The chemistry is identical, so every difference below comes from the condition. Both yield at about 470 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Normalized versus thermomechanically controlled processed). S460 Normalized runs hotter in service (350°C vs 300°C continuous). On the shop floor, S460 TMCP welds better (excellent vs very good) and S460 TMCP forms better (68 vs 58 out of 100).

S460 Normalized vs S460 TMCP: 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.

S460 Normalized vs S460 TMCP — frequently asked
What is the difference between S460 Normalized and S460 TMCP?
S460 Normalized and S460 TMCP are two conditions of the same steel grade, S460: Normalized versus TMCP (thermomechanically controlled processed). The chemistry is identical, so every difference below comes from the condition. Both yield at about 470 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Normalized versus thermomechanically controlled processed).
Which condition does FabDigit quote by default, Normalized or TMCP?
Normalized is the default S460 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which welds better, S460 Normalized or S460 TMCP?
S460 TMCP. Its weldability rates excellent (85/100) against very good (75/100) for S460 Normalized.
