Steel A216 WCC vs A27 Grade 70-36
Steel · grade comparison
Steel A216 WCC and A27 Grade 70-36 are both steel grades. A216 WCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 290 MPa (42.1 ksi) for A27 Grade 70-36, about 9% more. A216 WCC is harder — 170 HB against 150 HB for A27 Grade 70-36 — which matters for wear surfaces and threads.
A216 WCCChoose it when strength drives the design, or when surface hardness matters.
A216 WCC vs A27 Grade 70-36: 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 WCC vs A27 Grade 70-36 — frequently asked
Is A216 WCC stronger than A27 Grade 70-36?
Yes. A216 WCC has a typical yield strength of 315 MPa (45.7 ksi) against 290 MPa (42.1 ksi) for A27 Grade 70-36 — about 9% more. Tensile strength is 520 MPa (75.4 ksi) vs 515 MPa (74.7 ksi).
Which is cheaper, A216 WCC or A27 Grade 70-36?
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 WCC or A27 Grade 70-36?
A216 WCC, by a small margin. Both rate good for machinability — 60/100 against 55/100 for A27 Grade 70-36; for welding the order is A216 WCC first (excellent, 85/100) then A27 Grade 70-36 (very good, 78/100).
