Stainless Steel 316LN Annealed vs 316LN CW 1/16 Hard
Stainless Steel · 316LN temper comparison
316LN Annealed and 316LN CW 1/16 Hard are two conditions of the same stainless steel grade, 316LN: Annealed versus CW 1/16 Hard (cold Worked 1/16 Hard). The chemistry is identical, so every difference below comes from the condition. 316LN CW 1/16 Hard is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 300 MPa (43.5 ksi) for 316LN Annealed, about 17% more; tensile strength follows at 650 MPa (94.3 ksi) vs 590 MPa (85.6 ksi). In exchange, 316LN Annealed is the more ductile: elongation 50% versus 40% for 316LN CW 1/16 Hard, and 316LN CW 1/16 Hard is harder (195 HB vs 155 HB). 316LN Annealed runs hotter in service (800°C vs 425°C continuous).
316LN AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
316LN CW 1/16 HardChoose it when strength drives the design.
316LN Annealed vs 316LN CW 1/16 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.
