9Cr18MoV Steel
9Cr18MoV, also written 90Cr18MoV, is a Chinese high-carbon martensitic stainless designation. The name indicates roughly 0.9% carbon and 18% chromium, with molybdenum and vanadium additions. Sellers often compare it with 440C, but that comparison does not prove equivalence. A scissor’s finished hardness, edge geometry and service life depend on its maker and heat treatment.
Read a steel claim as a four-layer record
A grade can be useful evidence, but a finished shear adds maker execution, geometry, condition, and service history. Apply to 9Cr18MoV Steel
- 01 Identify the grade Use a producer or traceable maker designation.
- 02 Name the source layer Separate mill data, maker data, seller copy, and measurement.
- 03 Record execution Heat treatment, geometry, assembly, and finished-blade values stay model-specific.
- 04 Keep the history Condition, use, care, impacts, and service affect the working edge.
Do not inferOne element, HRC value, country adjective, price tier, or steel name cannot rank sharpness, toughness, corrosion resistance, or service life.

Reading a specification
Secondary material summaries report differing composition and hardness ranges for 9Cr18MoV. They are useful starting points, but this entry has no mill datasheet or named scissor-maker measurement establishing a universal finished-blade HRC. Figures around 57–60 HRC sometimes appear in market descriptions; treat them as attributed claims for the product that supplies them, not as a guarantee of the designation.
A 9Cr18MoV label also does not identify the grind, tooth pattern, corrosion performance in disinfectants, or service interval. Compare named scissors with documented specifications and follow the maker’s care instructions.
440C comparison
Both names refer to high-carbon chromium stainless families, but 9Cr18MoV is not an established synonym for 440C. The final blade depends on composition within the applicable standard, heat treatment and finishing. See the 440C entry for its own specification boundary.

Frequently Asked Questions
3 answers you can open one at a timeIs 9Cr18MoV the Chinese equivalent of 440C?
The grades are often compared, but their names alone do not establish interchangeable compositions, heat treatments or finished-scissor performance.
What hardness should a 9Cr18MoV scissor have?
No mill or finished-model specification reviewed here establishes one universal range. Ask the scissor maker for the hardness of the exact model.
How often should 9Cr18MoV scissors be serviced?
Sharpen when the blades begin pushing or folding hair and follow the maker’s service guidance. The grade name does not set a service interval.
