Steel A216 WCA vs SC410
Steel · grade comparison
Steel A216 WCA and SC410 are both steel grades. Both yield at about 255 MPa — strength does not separate them. A216 WCA is the more ductile: elongation 31% versus 24% for SC410.
A216 WCAChoose it when the part is bent, formed or impact-loaded.
A216 WCA vs SC410: 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.

A216 WCA vs SC410 — frequently asked
What is the difference between A216 WCA and SC410?
Steel A216 WCA and SC410 are both steel grades. Both yield at about 255 MPa — strength does not separate them. A216 WCA is the more ductile: elongation 31% versus 24% for SC410.
Which is cheaper, A216 WCA or SC410?
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, A216 WCA or SC410?
A216 WCA, by a small margin. Both rate good for machinability — 68/100 against 62/100 for SC410; for welding the order is A216 WCA first (excellent, 85/100) then SC410 (very good, 78/100).
