Steel 35L vs A352 LCC
Steel · grade comparison
Steel 35L and A352 LCC are both steel grades. A352 LCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 290 MPa (42.1 ksi) for 35L, about 9% more. A352 LCC is the more ductile: elongation 26% versus 16% for 35L. A352 LCC conducts electricity better (10 % IACS vs 9 % IACS). On the shop floor, A352 LCC welds better (very good vs fair) and 35L sits in a lower cost tier (budget, $) than A352 LCC (standard, $$).
35LChoose it when cost is the deciding factor.
A352 LCCChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
35L vs A352 LCC: 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.

35L vs A352 LCC — frequently asked
Is A352 LCC stronger than 35L?
Yes. A352 LCC has a typical yield strength of 315 MPa (45.7 ksi) against 290 MPa (42.1 ksi) for 35L — about 9% more. Tensile strength is 525 MPa (76.1 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 35L or A352 LCC?
35L is the lower-cost material: it sits in the budget tier ($) while A352 LCC is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 35L or A352 LCC?
A352 LCC, by a small margin. Both rate good for machinability — 63/100 against 55/100 for 35L; for welding the order is A352 LCC first (very good, 80/100) then 35L (fair, 45/100).
