Stainless Steel 316Cb-1/2 Hard vs 316Cb Full Hard
Stainless Steel · 316Cb temper comparison
316Cb-1/2 Hard and 316Cb Full Hard are two conditions of the same stainless steel grade, 316Cb: 1/2 Hard (half hard) versus Full Hard. The chemistry is identical, so every difference below comes from the condition. 316Cb Full Hard is the stronger of the two: yield strength 1,010 MPa (146 ksi) against 800 MPa (116 ksi) for 316Cb-1/2 Hard, about 26% more; tensile strength follows at 1,320 MPa (191 ksi) vs 1,070 MPa (155 ksi). In exchange, 316Cb-1/2 Hard is the more ductile: elongation 8% versus 3% for 316Cb Full Hard, and 316Cb Full Hard is harder (385 HB vs 310 HB). On the shop floor, 316Cb-1/2 Hard welds better (very good vs good).
316Cb-1/2 HardChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
316Cb Full HardChoose it when strength drives the design.
316Cb-1/2 Hard vs 316Cb 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.

316Cb-1/2 Hard vs 316Cb Full Hard — frequently asked
Is 316Cb Full Hard stronger than 316Cb-1/2 Hard?
Yes. 316Cb Full Hard has a typical yield strength of 1,010 MPa (146 ksi) against 800 MPa (116 ksi) for 316Cb-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 316Cb 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, 316Cb-1/2 Hard or 316Cb Full Hard?
316Cb-1/2 Hard. Its machinability rates fair (35/100) against poor (30/100) for 316Cb Full Hard; for welding the order is 316Cb-1/2 Hard first (very good, 75/100) then 316Cb Full Hard (good, 65/100).
