1.4852 vs 1.4857: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless 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.

1.4852 vs 1.4857 — frequently asked
Is 1.4852 stronger than 1.4857?
Yes. 1.4852 has a typical yield strength of 270 MPa (39.2 ksi) against 250 MPa (36.3 ksi) for 1.4857 — about 8% more. Tensile strength is 500 MPa (72.5 ksi) vs 450 MPa (65.3 ksi).
Which is cheaper, 1.4852 or 1.4857?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, 1.4852 or 1.4857?
1.4852. Its weldability rates fair (50/100) against fair (45/100) for 1.4857.
