Steel S235J2G3-CD vs S235J2G3 +N HS
Steel · S235J2G3 temper comparison
S235J2G3-CD and S235J2G3 +N HS are two conditions of the same steel grade, S235J2G3: CD (cold drawn) versus +N HS (+N heavy section). The chemistry is identical, so every difference below comes from the condition. S235J2G3-CD is the stronger of the two: yield strength 400 MPa (58 ksi) against 225 MPa (32.6 ksi) for S235J2G3 +N HS, about 78% more; tensile strength follows at 500 MPa (72.5 ksi) vs 400 MPa (58 ksi). In exchange, S235J2G3 +N HS is the more ductile: elongation 25% versus 9% for S235J2G3-CD, and S235J2G3-CD is harder (155 HB vs 115 HB). S235J2G3 +N HS runs hotter in service (350°C vs 300°C continuous).

S235J2G3 +N HSChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S235J2G3-CD vs S235J2G3 +N HS: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all 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.
