Stainless Steel 316Ti-1/2 Hard vs 316Ti Hot Rolled
Stainless Steel · 316Ti temper comparison
316Ti-1/2 Hard and 316Ti Hot Rolled are two conditions of the same stainless steel grade, 316Ti: 1/2 Hard (half hard) versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 316Ti-1/2 Hard is the stronger of the two: yield strength 690 MPa (100 ksi) against 250 MPa (36.3 ksi) for 316Ti Hot Rolled, about 176% more; tensile strength follows at 930 MPa (135 ksi) vs 570 MPa (82.7 ksi). In exchange, 316Ti Hot Rolled is the more ductile: elongation 42% versus 12% for 316Ti-1/2 Hard, and 316Ti-1/2 Hard is harder (260 HB vs 165 HB). 316Ti Hot Rolled runs hotter in service (800°C vs 425°C continuous). On the shop floor, 316Ti Hot Rolled welds better (excellent vs very good).

316Ti-1/2 Hard vs 316Ti 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.

316Ti-1/2 Hard vs 316Ti Hot Rolled — frequently asked
Is 316Ti-1/2 Hard stronger than 316Ti Hot Rolled?
Yes. 316Ti-1/2 Hard has a typical yield strength of 690 MPa (100 ksi) against 250 MPa (36.3 ksi) for 316Ti Hot Rolled — about 176% more. Tensile strength is 930 MPa (135 ksi) vs 570 MPa (82.7 ksi).
Which condition does FabDigit quote by default, 1/2 Hard or Hot Rolled?
Solution Annealed is the default 316Ti condition in the FabDigit quote flow (neither 1/2 Hard nor Hot Rolled). 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, 316Ti-1/2 Hard or 316Ti Hot Rolled?
316Ti-1/2 Hard, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for 316Ti Hot Rolled; for welding the order is 316Ti Hot Rolled first (excellent, 85/100) then 316Ti-1/2 Hard (very good, 72/100).
