Steel 50CrV4 Annealed vs 50CrV4 Q&T

Steel · 50CrV4 temper comparison

50CrV4 Annealed and 50CrV4 Q&T are two conditions of the same steel grade, 50CrV4: Annealed versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 50CrV4 Q&T is the stronger of the two: yield strength 1,050 MPa (152 ksi) against 460 MPa (66.7 ksi) for 50CrV4 Annealed, about 128% more; tensile strength follows at 1,250 MPa (181 ksi) vs 780 MPa (113 ksi). In exchange, 50CrV4 Annealed is the more ductile: elongation 18% versus 10% for 50CrV4 Q&T, and 50CrV4 Q&T is harder (375 HB vs 225 HB). 50CrV4 Q&T runs hotter in service (350°C vs 250°C continuous). On the shop floor, 50CrV4 Annealed machines more easily (good vs fair) and 50CrV4 Annealed welds better (25 vs 15 out of 100).
