Steel 30Q130 vs 50W470
Steel · grade comparison
Steel 30Q130 and 50W470 are both steel grades. 50W470 is the stronger of the two: tensile strength 440 MPa (63.8 ksi) against 345 MPa (50 ksi) for 30Q130, about 28% more. 50W470 is the more ductile: elongation 30% versus 8% for 30Q130, and 30Q130 is harder (160 HB vs 152 HB). 50W470 is stiffer (190 GPa vs 120 GPa) and 30Q130 runs hotter in service (200°C vs 180°C continuous). On the shop floor, 50W470 welds better (good vs fair).
30Q130Choose it when the part sees heat.
50W470Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
30Q130 vs 50W470: 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 50W470 — frequently asked
Is 50W470 stronger than 30Q130?
Yes. 50W470 has a typical tensile strength of 440 MPa (63.8 ksi) against 345 MPa (50 ksi) for 30Q130 — about 28% more.
Which is cheaper, 30Q130 or 50W470?
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 50W470?
50W470, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 30Q130; for welding the order is 50W470 first (good, 55/100) then 30Q130 (fair, 35/100).
