Stainless Steel 201 Annealed vs 201 Hot Rolled
Stainless Steel · 201 temper comparison
201 Annealed and 201 Hot Rolled are two conditions of the same stainless steel grade, 201: Annealed versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 201 Annealed is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 360 MPa (52.2 ksi) for 201 Hot Rolled, about 6% more. 201 Annealed is harder — 190 HB against 170 HB for 201 Hot Rolled — which matters for wear surfaces and threads.
201 AnnealedChoose it when strength drives the design, or when surface hardness matters.
201 Annealed vs 201 Hot Rolled: 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.
