Stainless Steel 1.4373-1/2 Hard vs 1.4373 Full Hard
Stainless Steel · 1.4373 temper comparison
1.4373-1/2 Hard and 1.4373 Full Hard are two conditions of the same stainless steel grade, 1.4373: 1/2 Hard (half hard) versus Full Hard. The chemistry is identical, so every difference below comes from the condition. 1.4373 Full Hard is the stronger of the two: yield strength 1,030 MPa (149 ksi) against 820 MPa (119 ksi) for 1.4373-1/2 Hard, about 26% more; tensile strength follows at 1,320 MPa (191 ksi) vs 1,070 MPa (155 ksi). In exchange, 1.4373-1/2 Hard is the more ductile: elongation 12% versus 5% for 1.4373 Full Hard, and 1.4373 Full Hard is harder (380 HB vs 310 HB). On the shop floor, 1.4373-1/2 Hard welds better (good vs fair).
1.4373-1/2 HardChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
1.4373 Full HardChoose it when strength drives the design.
1.4373-1/2 Hard vs 1.4373 Full Hard: 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.

1.4373-1/2 Hard vs 1.4373 Full Hard — frequently asked
Is 1.4373 Full Hard stronger than 1.4373-1/2 Hard?
Yes. 1.4373 Full Hard has a typical yield strength of 1,030 MPa (149 ksi) against 820 MPa (119 ksi) for 1.4373-1/2 Hard — about 26% more. Tensile strength is 1,320 MPa (191 ksi) vs 1,070 MPa (155 ksi).
Which condition does FabDigit quote by default, 1/2 Hard or Full Hard?
Annealed is the default 1.4373 condition in the FabDigit quote flow (neither 1/2 Hard nor Full Hard). 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, 1.4373-1/2 Hard or 1.4373 Full Hard?
1.4373-1/2 Hard, by a small margin. Both rate fair for machinability — 42/100 against 37/100 for 1.4373 Full Hard; for welding the order is 1.4373-1/2 Hard first (good, 55/100) then 1.4373 Full Hard (fair, 45/100).
