Steel 49MnVS3 Cold Drawn vs 49MnVS3 +S
Steel · 49MnVS3 temper comparison
49MnVS3 Cold Drawn and 49MnVS3 +S are two conditions of the same steel grade, 49MnVS3: Cold Drawn versus +S (treated for cold shearing / softened bar). The chemistry is identical, so every difference below comes from the condition. 49MnVS3 Cold Drawn is the stronger of the two: yield strength 790 MPa (115 ksi) against 450 MPa (65.3 ksi) for 49MnVS3 +S, about 76% more; tensile strength follows at 930 MPa (135 ksi) vs 750 MPa (109 ksi). In exchange, 49MnVS3 +S is the more ductile: elongation 17% versus 8% for 49MnVS3 Cold Drawn, and 49MnVS3 Cold Drawn is harder (280 HB vs 215 HB). 49MnVS3 +S runs hotter in service (350°C vs 300°C continuous). On the shop floor, 49MnVS3 +S welds better (30 vs 20 out of 100).

49MnVS3 Cold Drawn vs 49MnVS3 +S: 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.

49MnVS3 Cold Drawn vs 49MnVS3 +S — frequently asked
Is 49MnVS3 Cold Drawn stronger than 49MnVS3 +S?
Yes. 49MnVS3 Cold Drawn has a typical yield strength of 790 MPa (115 ksi) against 450 MPa (65.3 ksi) for 49MnVS3 +S — about 76% more. Tensile strength is 930 MPa (135 ksi) vs 750 MPa (109 ksi).
Which condition does FabDigit quote by default, Cold Drawn or +S?
As Forged is the default 49MnVS3 condition in the FabDigit quote flow (neither Cold Drawn nor +S). 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 welds better, 49MnVS3 Cold Drawn or 49MnVS3 +S?
49MnVS3 +S. Its weldability rates poor (30/100) against poor (20/100) for 49MnVS3 Cold Drawn.
