Steel A216 WCC vs LCA

Steel · grade comparison

Steel A216 WCC and LCA are both steel grades. A216 WCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 250 MPa (36.3 ksi) for LCA, about 26% more; tensile strength follows at 520 MPa (75.4 ksi) vs 470 MPa (68.2 ksi). In exchange, LCA is the more ductile: elongation 30% versus 25% for A216 WCC, and A216 WCC is harder (170 HB vs 150 HB).

A216 WCCChoose it when strength drives the design.

LCAChoose it when the part is bent, formed or impact-loaded.

A216 WCC vs LCA — frequently asked

Is A216 WCC stronger than LCA?

Yes. A216 WCC has a typical yield strength of 315 MPa (45.7 ksi) against 250 MPa (36.3 ksi) for LCA — about 26% more. Tensile strength is 520 MPa (75.4 ksi) vs 470 MPa (68.2 ksi).

Which is cheaper, A216 WCC or LCA?

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.

When should I choose A216 WCC over LCA?

Pick A216 WCC when strength drives the design. Pick LCA when the part is bent, formed or impact-loaded.
