Steel A352 LCC vs LCA

Steel · grade comparison

Steel A352 LCC and LCA are both steel grades. A352 LCC 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 525 MPa (76.1 ksi) vs 470 MPa (68.2 ksi). In exchange, LCA is the more ductile: elongation 30% versus 26% for A352 LCC.

A352 LCC vs LCA — frequently asked

Is A352 LCC stronger than LCA?

Yes. A352 LCC 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 525 MPa (76.1 ksi) vs 470 MPa (68.2 ksi).

Which is cheaper, A352 LCC 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.

Which is easier to machine, A352 LCC or LCA?

A352 LCC, by a small margin. Both rate good for machinability — 63/100 against 58/100 for LCA; for welding the order is LCA first (excellent, 85/100) then A352 LCC (very good, 80/100).
