Steel A27 Grade 60-30 vs ZG230-450
Steel · grade comparison
Steel A27 Grade 60-30 and ZG230-450 are both steel grades. Both yield at about 260 MPa — strength does not separate them. A27 Grade 60-30 is the more ductile: elongation 28% versus 24% for ZG230-450, and ZG230-450 is harder (150 HB vs 131 HB). On the shop floor, A27 Grade 60-30 welds better (excellent vs very good) and A27 Grade 60-30 sits in a lower cost tier (budget, $) than ZG230-450 (standard, $$).

A27 Grade 60-30 vs ZG230-450: 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.
