Stainless Steel 310MoLN Annealed vs 310MoLN-CD
Stainless Steel · 310MoLN temper comparison
310MoLN Annealed and 310MoLN-CD are two conditions of the same stainless steel grade, 310MoLN: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 310MoLN-CD is the stronger of the two: yield strength 510 MPa (74 ksi) against 300 MPa (43.5 ksi) for 310MoLN Annealed, about 70% more; tensile strength follows at 720 MPa (104 ksi) vs 600 MPa (87 ksi). In exchange, 310MoLN Annealed is the more ductile: elongation 45% versus 25% for 310MoLN-CD, and 310MoLN-CD is harder (220 HB vs 165 HB). 310MoLN Annealed runs hotter in service (550°C vs 425°C continuous).
310MoLN AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
310MoLN-CDChoose it when strength drives the design.
310MoLN Annealed vs 310MoLN-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.
