Steel 35# vs A217 WC1
Steel · grade comparison
Steel 35# and A217 WC1 are both steel grades. 35# is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 290 MPa (42.1 ksi) for A217 WC1, about 14% more; tensile strength follows at 560 MPa (81.2 ksi) vs 500 MPa (72.5 ksi). In exchange, A217 WC1 is the more ductile: elongation 28% versus 22% for 35#, and 35# is harder (160 HB vs 150 HB). A217 WC1 runs hotter in service (500°C vs 400°C continuous) and 35# conducts heat better (49 W/m·K vs 42 W/m·K). On the shop floor, A217 WC1 welds better (very good vs good) and 35# sits in a lower cost tier (budget, $) than A217 WC1 (standard, $$).
35#Choose it when strength drives the design, or when cost is the deciding factor.
A217 WC1Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
35# vs A217 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.
