Product Description

 

1.4125 ZDF-9 9Cr18Mo SUS440C Stainless Steel

9Cr18Mo and SUS440C martensitic stainless steels are high-carbon, high-chromium alloys known for their excellent hardness, superior wear resistance, and strong corrosion resistance. These materials are widely used in the manufacture of cutting tools, industrial blades, scissors, surgical instruments, and precision mechanical components.

Thanks to their outstanding cutting-edge retention, corrosion resistance, and toughness, 9Cr18Mo and SUS440C stainless steels are especially suitable for applications requiring both durability and sharpness. Their ability to be heat-treated to high hardness while maintaining excellent mechanical properties makes them ideal materials for high-performance cutting tools and medical instruments.

• Care Tips

1. Keep it Clean:
Make sure to clean the steel with soft cloth gently using warm water and mild soap after you use it. Avoid abrasivecleaning products that may scratch or score the surface.

2. Prevent Corrosion:
Though 9Cri8MoV exhibits extremely good corrosion resistance, it is best if the tools are treated with a thin coat of oil or a rust-resistant coating if they are routinely exposed to strong chemicals or moisture.

3. Store Correctly:
Store parts and tools in a dry, well-ventilated space. Silica gel packets - to absorb moisture in cabinets or toolboxes.

 

• Main features and advantages of 9Cr18Mo

1)High hardness 

9Cr18Mo can reach 58- 62HRC, which is achieved after proper heat treatment.

2)Great corrosion resistance

9Cr18Mo attained oxidation and corrosion resistance in many complete environments, acidic and humid situations..

3)Excellent wear resistance

The 9Cr18Mo component adds molybdenum(Mo), achieving plasticity of the steel in the application of high durability and wear resistance.

4)Good machinability

9Cr18Mo has good toughness due to its composition, which means it can endure high amounts of mechanical stress and mechanical pressure during precision cutting. This also makes it better suited to applications that need complex design and reliable pheat treatmenterformance.
