Stainless Steel 2507 vs Zeron 100
Stainless Steel · grade comparison
Stainless Steel 2507 and Zeron 100 are both stainless steel grades, both super duplex ss. 2507 is the stronger of the two: tensile strength 880 MPa (128 ksi) against 830 MPa (120 ksi) for Zeron 100, about 6% more. 2507 is harder — 270 HB against 250 HB for Zeron 100 — which matters for wear surfaces and threads.
2507Choose it when strength drives the design, or when surface hardness matters.
2507 vs Zeron 100: 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.

2507 vs Zeron 100 — frequently asked
Is 2507 stronger than Zeron 100?
Yes. 2507 has a typical tensile strength of 880 MPa (128 ksi) against 830 MPa (120 ksi) for Zeron 100 — about 6% more.
Which is cheaper, 2507 or Zeron 100?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, 2507 or Zeron 100?
Zeron 100. Its weldability rates good (65/100) against good (60/100) for 2507.
