Steel 30Q130 vs Ingot Iron
Steel · grade comparison
Steel 30Q130 and Ingot Iron are both steel grades. 30Q130 is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 150 MPa (21.8 ksi) for Ingot Iron, about 110% more; tensile strength follows at 345 MPa (50 ksi) vs 275 MPa (39.9 ksi). In exchange, Ingot Iron is the more ductile: elongation 45% versus 8% for 30Q130, and 30Q130 is harder (160 HB vs 70 HB). Ingot Iron is stiffer (205 GPa vs 120 GPa) and Ingot Iron runs hotter in service (450°C vs 200°C continuous). On the shop floor, Ingot Iron welds better (excellent vs fair).
30Q130Choose it when strength drives the design.
Ingot IronChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
30Q130 vs Ingot Iron: 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.

30Q130 vs Ingot Iron — frequently asked
Is 30Q130 stronger than Ingot Iron?
Yes. 30Q130 has a typical yield strength of 315 MPa (45.7 ksi) against 150 MPa (21.8 ksi) for Ingot Iron — about 110% more. Tensile strength is 345 MPa (50 ksi) vs 275 MPa (39.9 ksi).
Which is cheaper, 30Q130 or Ingot Iron?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 30Q130 or Ingot Iron?
Ingot Iron, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 30Q130; for welding the order is Ingot Iron first (excellent, 95/100) then 30Q130 (fair, 35/100).
