Stainless Steel 1.4373 Cold Drawn vs 1.4373 Full Hard
Stainless Steel · 1.4373 temper comparison
1.4373 Cold Drawn and 1.4373 Full Hard are two conditions of the same stainless steel grade, 1.4373: Cold Drawn 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 600 MPa (87 ksi) for 1.4373 Cold Drawn, about 72% more; tensile strength follows at 1,320 MPa (191 ksi) vs 850 MPa (123 ksi). In exchange, 1.4373 Cold Drawn is the more ductile: elongation 20% versus 5% for 1.4373 Full Hard, and 1.4373 Full Hard is harder (380 HB vs 260 HB). 1.4373 Cold Drawn runs hotter in service (315°C vs 280°C continuous). On the shop floor, 1.4373 Cold Drawn welds better (good vs fair).
1.4373 Cold DrawnChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4373 Full HardChoose it when strength drives the design.
1.4373 Cold Drawn 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 Cold Drawn vs 1.4373 Full Hard — frequently asked
Is 1.4373 Full Hard stronger than 1.4373 Cold Drawn?
Yes. 1.4373 Full Hard has a typical yield strength of 1,030 MPa (149 ksi) against 600 MPa (87 ksi) for 1.4373 Cold Drawn — about 72% more. Tensile strength is 1,320 MPa (191 ksi) vs 850 MPa (123 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Full Hard?
Annealed is the default 1.4373 condition in the FabDigit quote flow (neither Cold Drawn 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 Cold Drawn or 1.4373 Full Hard?
1.4373 Cold Drawn, by a small margin. Both rate fair for machinability — 44/100 against 37/100 for 1.4373 Full Hard; for welding the order is 1.4373 Cold Drawn first (good, 60/100) then 1.4373 Full Hard (fair, 45/100).
