Stainless Steel CA28MWV-DT vs CA28MWV Q&T
Stainless Steel · CA28MWV temper comparison
CA28MWV-DT and CA28MWV Q&T are two conditions of the same stainless steel grade, CA28MWV: DT (double tempered (two tempers ≥ 690 °C) for long-term high-temperature…) versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. CA28MWV Q&T is the stronger of the two: yield strength 800 MPa (116 ksi) against 740 MPa (107 ksi) for CA28MWV-DT, about 8% more; tensile strength follows at 1,080 MPa (157 ksi) vs 1,010 MPa (146 ksi). In exchange, CA28MWV-DT is the more ductile: elongation 15% versus 12% for CA28MWV Q&T, and CA28MWV Q&T is harder (315 HB vs 293 HB).
CA28MWV-DTChoose it when the part is bent, formed or impact-loaded.
CA28MWV Q&TChoose it when strength drives the design.
CA28MWV-DT vs CA28MWV Q&T: 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.

CA28MWV-DT vs CA28MWV Q&T — frequently asked
Is CA28MWV Q&T stronger than CA28MWV-DT?
Yes. CA28MWV Q&T has a typical yield strength of 800 MPa (116 ksi) against 740 MPa (107 ksi) for CA28MWV-DT — about 8% more. Tensile strength is 1,080 MPa (157 ksi) vs 1,010 MPa (146 ksi).
Which condition does FabDigit quote by default, DT or Q&T?
N+T is the default CA28MWV condition in the FabDigit quote flow (neither DT nor Q&T). 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 CA28MWV-DT over CA28MWV Q&T?
Pick CA28MWV-DT when the part is bent, formed or impact-loaded. Pick CA28MWV Q&T when strength drives the design.
