Translate this pageGenerally, the 4140 annealed plate hardness is max 255HB, while the quenched and tempered (Q&T) plate 28-32HRC (280-320HB). So, when you have requirement of hardness, you should make it clear to supplier, to avoid the wrong material condition. Properties:When you have special mechanical properties, you would need heat treated plate for sure.

Prediction of the surface characteristic of 42CrMo after Jan 15, 2019 · The chemical composition of 42CrMo steel is shown in Table 2. The yield strength and tensile strength of 42CrMo steel are about 680 MPa and 920 MPa, and the hardness is about 280 HV. Fig. 7 is the CCT diagram of 42CrMo steel . In this CCT diagram, Ac1 and Ac3 are the start and complete temperatures of austenite formation.
It can be seen that the corrosion resistance of 45 # steel treated by QPQ is 5 times of that of 1Cr18Ni9Ti stainless steel, 70 times of hard chromium plating and 280 times of that of ordinary blackening. After other materials were treated by QPQ process, the neutral salt spray test could reach 100-300 hours. 3. Good fatigue resistance
