Steel A352 LCC vs G24Mn6
Steel · grade comparison
Steel A352 LCC and G24Mn6 are both steel grades. G24Mn6 is the stronger of the two: yield strength 440 MPa (63.8 ksi) against 315 MPa (45.7 ksi) for A352 LCC, about 40% 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 18% for G24Mn6, and G24Mn6 is harder (195 HB vs 155 HB). A352 LCC runs hotter in service (425°C vs 350°C continuous) and A352 LCC conducts heat better (50 W/m·K vs 45 W/m·K). On the shop floor, A352 LCC welds better (very good vs good).
A352 LCCChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
G24Mn6Choose it when strength drives the design.
A352 LCC vs G24Mn6: 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.

A352 LCC vs G24Mn6 — frequently asked
Is G24Mn6 stronger than A352 LCC?
Yes. G24Mn6 has a typical yield strength of 440 MPa (63.8 ksi) against 315 MPa (45.7 ksi) for A352 LCC — about 40% more. Tensile strength is 660 MPa (95.7 ksi) vs 525 MPa (76.1 ksi).
Which is cheaper, A352 LCC or G24Mn6?
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 G24Mn6?
A352 LCC, by a small margin. Both rate good for machinability — 63/100 against 55/100 for G24Mn6; for welding the order is A352 LCC first (very good, 80/100) then G24Mn6 (good, 62/100).
