Stainless Steel 348H Annealed vs 348H Cold Drawn
Stainless Steel · 348H temper comparison
348H Annealed and 348H Cold Drawn are two conditions of the same stainless steel grade, 348H: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 348H Cold Drawn is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 275 MPa (39.9 ksi) for 348H Annealed, about 75% more; tensile strength follows at 725 MPa (105 ksi) vs 620 MPa (89.9 ksi). In exchange, 348H Annealed is the more ductile: elongation 50% versus 25% for 348H Cold Drawn, and 348H Cold Drawn is harder (220 HB vs 160 HB).
348H AnnealedChoose it when the part is bent, formed or impact-loaded.
348H Cold DrawnChoose it when strength drives the design.
348H Annealed vs 348H Cold Drawn: 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.
