Why Should Steel Parts Be Quenched And Tempered? What

19 hours ago · The hardness of the 45 steel quenched and tempered parts after quenching should reach HRC56~59. The possibility of a large cross section is lower, but it cannot be lower than HRC48. Otherwise, it means that the workpiece has not been completely quenched, and sorbite or even ferrite may appear in the structure.What should the temperature be for oil quenching?Hardening: Heat to 800 to 845 °C (1475 to 1550 °F) for 15 minutes (minimum 15 minutes) per 25 mm (1 inch) thickness; oil quench to below 65 °C (150 °F), or quench in fused salt at 200 to 210 °C (390 to 410 °F), hold for 10 minutes, and then air-cool to below 65 °C (150 °F).See all results for this questionWhat are the mechanical properties of 4340 steel?In this work, the mechanical properties and microstructures of AISI 4340 high strength alloy steel under different tempering conditions are investigated.

Advantages of mechanical properties of quenched and tempered 40crni2mo, ordinary carbon killed steel plate: there is no gas in the steel plate, the impurity is relatively small, the stress is very uniform, and it has good welding performance. It is widely used in parts with high requirements. Disadvantages of ordinary carbon killed steel plate: the surface quality of the killed steel plate is not as good as that of boiling plates, there are concentrated shrinkage holes, and the killed steel plate price is more expensive.
