Steel A27 Grade 60-30 vs ZG310-570
Steel · grade comparison
Steel A27 Grade 60-30 and ZG310-570 are both steel grades. ZG310-570 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 260 MPa (37.7 ksi) for A27 Grade 60-30, about 31% more; tensile strength follows at 600 MPa (87 ksi) vs 485 MPa (70.3 ksi). In exchange, A27 Grade 60-30 is the more ductile: elongation 28% versus 19% for ZG310-570, and ZG310-570 is harder (185 HB vs 131 HB). On the shop floor, A27 Grade 60-30 welds better (excellent vs fair) and A27 Grade 60-30 sits in a lower cost tier (budget, $) than ZG310-570 (standard, $$).
A27 Grade 60-30Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
ZG310-570Choose it when strength drives the design.
A27 Grade 60-30 vs ZG310-570: 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.
