Steel W6Mo5Cr4V2 Cold Drawn vs W6Mo5Cr4V2 Q&T 62-64 HRC

Steel · W6Mo5Cr4V2 temper comparison

W6Mo5Cr4V2 Cold Drawn and W6Mo5Cr4V2 Q&T 62-64 HRC are two conditions of the same steel grade, W6Mo5Cr4V2: Cold Drawn versus Q&T 62-64 HRC (hardened 1210–1230 °C, triple tempered ~550–560 °C). The chemistry is identical, so every difference below comes from the condition. W6Mo5Cr4V2 Cold Drawn is the stronger of the two: yield strength 780 MPa (113 ksi) against 570 MPa (82.7 ksi) for W6Mo5Cr4V2 Q&T 62-64 HRC, about 37% more. W6Mo5Cr4V2 Cold Drawn is the more ductile: elongation 6% versus 0.5% for W6Mo5Cr4V2 Q&T 62-64 HRC, and W6Mo5Cr4V2 Cold Drawn is harder (290 HB vs 240 HB). W6Mo5Cr4V2 Q&T 62-64 HRC runs hotter in service (580°C vs 400°C continuous) and W6Mo5Cr4V2 Cold Drawn conducts heat better (24 W/m·K vs 21 W/m·K). On the shop floor, W6Mo5Cr4V2 Cold Drawn machines more easily (fair vs not recommended).
