Steel A27 Grade 60-30 vs A352 LCC
Steel · grade comparison
Steel A27 Grade 60-30 and A352 LCC are both steel grades. A352 LCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 260 MPa (37.7 ksi) for A27 Grade 60-30, about 21% more; tensile strength follows at 525 MPa (76.1 ksi) vs 485 MPa (70.3 ksi). A352 LCC is harder — 155 HB against 131 HB for A27 Grade 60-30 — which matters for wear surfaces and threads. On the shop floor, A27 Grade 60-30 sits in a lower cost tier (budget, $) than A352 LCC (standard, $$).
A27 Grade 60-30Choose it when cost is the deciding factor.
A352 LCCChoose it when strength drives the design, or when surface hardness matters.
A27 Grade 60-30 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.
