Steel We use

Jiuli Knives manufactures high-precision industrial blades using premium Tungsten and HSS,Tool steel  sourced directly from top steel plants. We provide 24/7 technical support for packaging, medical, and tech sectors, delivering durable, custom-engineered solutions for all your unique cutting requirements.

Our Main Steel Type

In industrial manufacturing and tool production, achieving the correct HRC (Rockwell Hardness Scale C) is critical for balancing wear resistance and toughness.
