Stainless Steel 347H Cold Drawn vs 347H Hot Finished
Stainless Steel · 347H temper comparison
347H Cold Drawn and 347H Hot Finished are two conditions of the same stainless steel grade, 347H: Cold Drawn versus Hot Finished (hot Finished (hot rolled, annealed and descaled) bar / seamless pipe). The chemistry is identical, so every difference below comes from the condition. 347H Cold Drawn is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 250 MPa (36.3 ksi) for 347H Hot Finished, about 108% more; tensile strength follows at 790 MPa (115 ksi) vs 585 MPa (84.8 ksi). In exchange, 347H Hot Finished is the more ductile: elongation 45% versus 28% for 347H Cold Drawn, and 347H Cold Drawn is harder (225 HB vs 170 HB).
347H Cold DrawnChoose it when strength drives the design.
347H Hot FinishedChoose it when the part is bent, formed or impact-loaded.
347H Cold Drawn vs 347H Hot Finished: 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.

347H Cold Drawn vs 347H Hot Finished — frequently asked
Is 347H Cold Drawn stronger than 347H Hot Finished?
Yes. 347H Cold Drawn has a typical yield strength of 520 MPa (75.4 ksi) against 250 MPa (36.3 ksi) for 347H Hot Finished — about 108% more. Tensile strength is 790 MPa (115 ksi) vs 585 MPa (84.8 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Hot Finished?
Solution Annealed is the default 347H condition in the FabDigit quote flow (neither Cold Drawn nor Hot Finished). 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.
Which is easier to machine, 347H Cold Drawn or 347H Hot Finished?
347H Cold Drawn, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for 347H Hot Finished.
