Stainless Steel 316H 1/2H vs 316H-CD
Stainless Steel · 316H temper comparison
316H 1/2H and 316H-CD are two conditions of the same stainless steel grade, 316H: 1/2H (half hard) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 316H 1/2H is the stronger of the two: yield strength 800 MPa (116 ksi) against 500 MPa (72.5 ksi) for 316H-CD, about 60% more; tensile strength follows at 1,070 MPa (155 ksi) vs 700 MPa (102 ksi). In exchange, 316H-CD is the more ductile: elongation 28% versus 9% for 316H 1/2H, and 316H 1/2H is harder (310 HB vs 220 HB). 316H-CD runs hotter in service (815°C vs 400°C continuous). On the shop floor, 316H-CD machines more easily (fair vs poor) and 316H-CD welds better (very good vs good).
316H 1/2HChoose it when strength drives the design.
316H-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
316H 1/2H vs 316H-CD: 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.

316H 1/2H vs 316H-CD — frequently asked
Is 316H 1/2H stronger than 316H-CD?
Yes. 316H 1/2H has a typical yield strength of 800 MPa (116 ksi) against 500 MPa (72.5 ksi) for 316H-CD — about 60% more. Tensile strength is 1,070 MPa (155 ksi) vs 700 MPa (102 ksi).
Which condition does FabDigit quote by default, 1/2H or CD?
Annealed is the default 316H condition in the FabDigit quote flow (neither 1/2H nor CD). 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, 316H 1/2H or 316H-CD?
316H-CD. Its machinability rates fair (42/100) against poor (30/100) for 316H 1/2H; for welding the order is 316H-CD first (very good, 75/100) then 316H 1/2H (good, 60/100).
