Steel A27 Grade 60-30 vs LCA
Steel · grade comparison
Steel A27 Grade 60-30 and LCA are both steel grades. Both yield at about 260 MPa — strength does not separate them. LCA is harder — 150 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 LCA (standard, $$).

LCAChoose it when surface hardness matters.
A27 Grade 60-30 vs LCA: 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.
