Steel ZG230-450 vs ZG310-570
Steel · grade comparison
Steel ZG230-450 and ZG310-570 are both steel grades. ZG310-570 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 255 MPa (37 ksi) for ZG230-450, about 33% more; tensile strength follows at 600 MPa (87 ksi) vs 480 MPa (69.6 ksi). In exchange, ZG230-450 is the more ductile: elongation 24% versus 19% for ZG310-570, and ZG310-570 is harder (185 HB vs 150 HB). On the shop floor, ZG230-450 welds better (very good vs fair).
ZG230-450Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
ZG310-570Choose it when strength drives the design.
ZG230-450 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.

ZG230-450 vs ZG310-570 — frequently asked
Is ZG310-570 stronger than ZG230-450?
Yes. ZG310-570 has a typical yield strength of 340 MPa (49.3 ksi) against 255 MPa (37 ksi) for ZG230-450 — about 33% more. Tensile strength is 600 MPa (87 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, ZG230-450 or ZG310-570?
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.
Which is easier to machine, ZG230-450 or ZG310-570?
ZG230-450. Its machinability rates good (58/100) against fair (50/100) for ZG310-570; for welding the order is ZG230-450 first (very good, 78/100) then ZG310-570 (fair, 45/100).
