Steel A352 LCC vs GE320

Steel · grade comparison

Steel A352 LCC and GE320 are both steel grades. GE320 is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 315 MPa (45.7 ksi) for A352 LCC, about 14% more; tensile strength follows at 660 MPa (95.7 ksi) vs 525 MPa (76.1 ksi). In exchange, A352 LCC is the more ductile: elongation 26% versus 13% for GE320, and GE320 is harder (195 HB vs 155 HB). On the shop floor, A352 LCC machines more easily (good vs fair) and A352 LCC welds better (very good vs fair).

A352 LCCChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

GE320Choose it when strength drives the design.

A352 LCC vs GE320 — frequently asked

Is GE320 stronger than A352 LCC?

Yes. GE320 has a typical yield strength of 360 MPa (52.2 ksi) against 315 MPa (45.7 ksi) for A352 LCC — about 14% more. Tensile strength is 660 MPa (95.7 ksi) vs 525 MPa (76.1 ksi).

Which is cheaper, A352 LCC or GE320?

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 GE320?

A352 LCC. Its machinability rates good (63/100) against fair (50/100) for GE320; for welding the order is A352 LCC first (very good, 80/100) then GE320 (fair, 45/100).
