Heat treatment of 9Cr18MoV

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

Main features and advantages of 9Cr18MoV

High hardness and wear resistance9Cr18MoV after proper heat treatment, its hardness can reach 58-60HRC, this step makes stainless steel has excellent wear resistance, widely used in cutting tools, tools and other high wear occasions.
Excellent corrosion resistanceThe material contains a high chromium content (about 18%), which provides good corrosion resistance and enables it to maintain stable performance in wet, chemical environments.
Excellent toughness9Cr18MoV has good heat treatment performance and can obtain the required hardness and toughness through a suitable heat treatment process, which is suitable for high-precision manufacturing requirements.

Applications of 9Cr18MoV Stainless Steel

Knife：
Because 9Cr18MoV stainless steel has high hardness, excellent edge protection and good corrosion resistance, it is widely used in the tool industry. It is commonly used to make various types of knives such as folding knives, hunting knives and kitchen knives, making it ideal for high-performance cutting tools.

Hair Scissors:
Due to the high material requirements of the barber scissors, it is necessary to have a certain sharp blade and durable cutting ability. And the addition of vanadium provides the effect of refining grains, so that the scissors maintain a certain toughness while maintaining high hardness, reducing the risk of edge breakage and cracking.

Medical equipment:
Because 9Cr18MoV has high corrosion resistance and antibacterial properties, such as scalpels, surgical scissors, etc., these tools can be kept sharp in long-term use, and it is easy to clean and disinfect.

FAQ

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.
