Stainless Steel E410-17 vs E410-QT
Stainless Steel · E410 temper comparison
E410-17 and E410-QT are two conditions of the same stainless steel grade, E410: E410-17 (silica-bearing rutile coating, AC or DCEP) versus QT (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. E410-QT is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 395 MPa (57.3 ksi) for E410-17, about 19% more; tensile strength follows at 640 MPa (92.8 ksi) vs 555 MPa (80.5 ksi). E410-QT is harder — 220 HB against 198 HB for E410-17 — which matters for wear surfaces and threads.
E410-QTChoose it when strength drives the design, or when surface hardness matters.
E410-17 vs E410-QT: 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.

E410-17 vs E410-QT — frequently asked
Is E410-QT stronger than E410-17?
Yes. E410-QT has a typical yield strength of 470 MPa (68.2 ksi) against 395 MPa (57.3 ksi) for E410-17 — about 19% more. Tensile strength is 640 MPa (92.8 ksi) vs 555 MPa (80.5 ksi).
Which condition does FabDigit quote by default, E410-17 or QT?
PWHT is the default E410 condition in the FabDigit quote flow (neither E410-17 nor QT). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose E410-17 over E410-QT?
Pick E410-QT when strength drives the design, or when surface hardness matters.
