High Carbon Stainless Steel58–62 HRCConventional Ingot Steel Process

Composition

Core alloying elements define the baseline trade-off between wear resistance, corrosion behavior, and toughness.

Material Overview

GB 9Cr18MoV is one of the most common Chinese stainless steels used in knife production. It offers a relatively high carbon content compared to other budget stainless steels, allowing it to reach higher hardness and better edge retention. With added chromium, molybdenum, and vanadium, it achieves a balanced performance profile suitable for general-purpose cutting tasks. While it does not match premium Japanese or powder metallurgy steels, it is a strong value option in its category.
