Steel A352 Grade LC2-1 vs WC1
Steel · grade comparison
Steel A352 Grade LC2-1 and WC1 are both steel grades. A352 Grade LC2-1 is the stronger of the two: yield strength 640 MPa (92.8 ksi) against 305 MPa (44.2 ksi) for WC1, about 110% more; tensile strength follows at 800 MPa (116 ksi) vs 520 MPa (75.4 ksi). In exchange, WC1 is the more ductile: elongation 28% versus 20% for A352 Grade LC2-1, and A352 Grade LC2-1 is harder (235 HB vs 160 HB). WC1 runs hotter in service (455°C vs 400°C continuous). On the shop floor, WC1 machines more easily (good vs fair), WC1 welds better (very good vs fair), and WC1 sits in a lower cost tier (standard, $$) than A352 Grade LC2-1 (premium, $$$).
A352 Grade LC2-1Choose it when strength drives the design.
WC1Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
A352 Grade LC2-1 vs WC1: 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.
