Stainless Steel 1.4319 1/2H vs 1.4319 Annealed
Stainless Steel · 1.4319 temper comparison
1.4319 1/2H and 1.4319 Annealed are two conditions of the same stainless steel grade, 1.4319: 1/2H (half hard) versus Annealed. The chemistry is identical, so every difference below comes from the condition. 1.4319 1/2H is the stronger of the two: yield strength 820 MPa (119 ksi) against 290 MPa (42.1 ksi) for 1.4319 Annealed, about 183% more; tensile strength follows at 1,080 MPa (157 ksi) vs 700 MPa (102 ksi). In exchange, 1.4319 Annealed is the more ductile: elongation 55% versus 16% for 1.4319 1/2H, and 1.4319 1/2H is harder (310 HB vs 170 HB). 1.4319 Annealed runs hotter in service (800°C vs 300°C continuous). On the shop floor, 1.4319 Annealed welds better (very good vs good).

1.4319 1/2H vs 1.4319 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.

1.4319 1/2H vs 1.4319 Annealed — frequently asked
Is 1.4319 1/2H stronger than 1.4319 Annealed?
Yes. 1.4319 1/2H has a typical yield strength of 820 MPa (119 ksi) against 290 MPa (42.1 ksi) for 1.4319 Annealed — about 183% more. Tensile strength is 1,080 MPa (157 ksi) vs 700 MPa (102 ksi).
Which condition does FabDigit quote by default, 1/2H or Annealed?
Annealed is the default 1.4319 condition in the FabDigit quote flow. 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, 1.4319 1/2H or 1.4319 Annealed?
1.4319 Annealed, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for 1.4319 1/2H; for welding the order is 1.4319 Annealed first (very good, 70/100) then 1.4319 1/2H (good, 60/100).
