Steel M19 Annealed vs M19 Cold Rolled
Steel · M19 temper comparison
M19 Annealed and M19 Cold Rolled are two conditions of the same steel grade, M19: Annealed versus Cold Rolled. The chemistry is identical, so every difference below comes from the condition. M19 Cold Rolled is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 340 MPa (49.3 ksi) for M19 Annealed, about 47% more; tensile strength follows at 580 MPa (84.1 ksi) vs 460 MPa (66.7 ksi). In exchange, M19 Annealed is the more ductile: elongation 25% versus 8% for M19 Cold Rolled, and M19 Cold Rolled is harder (195 HV vs 150 HV).
M19 AnnealedChoose it when the part is bent, formed or impact-loaded.
M19 Cold RolledChoose it when strength drives the design.
M19 Annealed vs M19 Cold Rolled: 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.
