Steel A352 LCC vs SC450
Steel · grade comparison
Steel A352 LCC and SC450 are both steel grades. A352 LCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 275 MPa (39.9 ksi) for SC450, about 15% more; tensile strength follows at 525 MPa (76.1 ksi) vs 495 MPa (71.8 ksi). A352 LCC is harder — 155 HB against 145 HB for SC450 — which matters for wear surfaces and threads.
A352 LCCChoose it when strength drives the design, or when surface hardness matters.
A352 LCC vs SC450: 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 SC450 — frequently asked
Is A352 LCC stronger than SC450?
Yes. A352 LCC has a typical yield strength of 315 MPa (45.7 ksi) against 275 MPa (39.9 ksi) for SC450 — about 15% more. Tensile strength is 525 MPa (76.1 ksi) vs 495 MPa (71.8 ksi).
Which is cheaper, A352 LCC or SC450?
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 A352 LCC over SC450?
Pick A352 LCC when strength drives the design, or when surface hardness matters.
