Stainless Steel 330 Cold Drawn vs 330 Solution Annealed
Stainless Steel · 330 temper comparison
330 Cold Drawn and 330 Solution Annealed are two conditions of the same stainless steel grade, 330: Cold Drawn versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. 330 Cold Drawn is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 270 MPa (39.2 ksi) for 330 Solution Annealed, about 78% more; tensile strength follows at 700 MPa (102 ksi) vs 585 MPa (84.8 ksi). In exchange, 330 Solution Annealed is the more ductile: elongation 43% versus 25% for 330 Cold Drawn, and 330 Cold Drawn is harder (200 HB vs 150 HB).
330 Cold DrawnChoose it when strength drives the design.
330 Solution AnnealedChoose it when the part is bent, formed or impact-loaded.
330 Cold Drawn vs 330 Solution Annealed: 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.
