Stainless Steel 1.4003 Annealed-CR-2B vs 1.4003-HR
Stainless Steel · 1.4003 temper comparison
1.4003 Annealed-CR-2B and 1.4003-HR are two conditions of the same stainless steel grade, 1.4003: Annealed-CR-2B (annealed 2B/2D) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Both yield at about 350 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (annealed 2B/2D versus hot rolled). 1.4003 Annealed-CR-2B is the more ductile: elongation 25% versus 22% for 1.4003-HR, and 1.4003-HR is harder (180 HB vs 165 HB).
1.4003 Annealed-CR-2BChoose it when the part is bent, formed or impact-loaded.
1.4003 Annealed-CR-2B vs 1.4003-HR: 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.
