• Main features and advantages of 9Cr18MoV

1)High hardness and wear resistance

9Cr18MoV, after proper heat treatment, its hardness can reach 58- 60HRC. This step makes stainless steel have excellent wear resistance, widely used in cutting tools, tools, and other high-wear occasions.

2)Excellent corrosion resistance

The material contains a high chromium content (about 18%), which provides good corrosion resistance and enables it to maintain stable performance in wet, chemical environments.

3)Excellent toughness

9Cr18MoV 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

Applications of 9Cr18MoV stainless 
 

• Knife:

  Because 9crl8MoV 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 
  

• 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, and can also support length customization, cutting processing and etc, according to the 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 a stable supply and timely delivery.

• Are the other stainless steel 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.
