| Step | Temperature Range | Hoding Time | Process Description |
| Heating | 1150 ± 10℃ | 20 – 100 minutes | Heat to the specified temperature to uniformly dissolve alloying elements |
| Cooling | 980 ± 10℃ | 20 – 100 minutes | Cool in the furnace to further homogenize the steel structure |
| Forging | 1000℃ ~ 1150℃ | Forging base temperature, final forging temperature between 780℃～900℃ | |
| Normalizing | First heating：800 ± 10℃ | 30 – 120 minutes | First heating to 800℃, then raise to 920℃, air cool to 200-300℃ |
| Second heating：650 ±10 ℃ | 30 – 120 minutes | Second heating to 650℃, then raise to 750℃, air cool to room temperature | |
| Tempering | 220 ~ 240 ℃ | 30 – 100 minutes | Tempering followed by air cooling to room temperature |
Is 9Cr18MoV suitable for use in a highly humid environment?
9Cr18MoV can work well in a high moisture environment, as its high chromium content allows it to form a chromium oxide protective layer, which improves the corrosion resistance of the blade.
Are special surface treatment or finishing services available?
Yes, we can provide customer surface treatment of materials such as polishing, sandblasting, heat treatment and etc, also can support length customization, cutting processing and etc according to customer’s needs.
Can it place high-volume production orders?
Yes, we not only assist with the procurement of small amounts, but also specialize in producing large quantities of raw materials for customers, and can also supply stable supply and timely delivery.
Are the other stainless steels alloys compatible with 9Cr18MoV for alloying or machining?
Yes, there is 9Cr18MoV that can be alloyed with other stainless steels for specialized applications, but it is common for 9Cr18MoV to be machined like other martensitic stainless steels, so it can be applied in industries that require precise manufacturing.
Is 9Cr18MoV easy to sharpen?
9Cr18MoV is easier to sharpen than most high-carbon steels and offers incredible edge retention so it’s a great choice for cutting tools that need to stay sharp for a long time. But you should use proper techniques and tools to maintain the edge well.
