Steel WC1 vs WC11
Steel · grade comparison
Steel WC1 and WC11 are both steel grades. WC11 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 305 MPa (44.2 ksi) for WC1, about 36% more; tensile strength follows at 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi). In exchange, WC1 is the more ductile: elongation 28% versus 22% for WC11, and WC11 is harder (190 HB vs 160 HB). WC11 runs hotter in service (565°C vs 455°C continuous). On the shop floor, WC1 welds better (very good vs good).
WC1Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
WC11Choose it when strength drives the design, or when the part sees heat.
WC1 vs WC11: 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.

WC1 vs WC11 — frequently asked
Is WC11 stronger than WC1?
Yes. WC11 has a typical yield strength of 415 MPa (60.2 ksi) against 305 MPa (44.2 ksi) for WC1 — about 36% more. Tensile strength is 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, WC1 or WC11?
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 welds better, WC1 or WC11?
WC1. Its weldability rates very good (70/100) against good (60/100) for WC11.
