The Unique Advantages of SUS410 Stainless Steel Plate in Knife Manufacturing

SUS410 stainless steel plate, a martensitic stainless steel under JIS G4304, is widely recognized in the knife manufacturing industry for its unique balance of hardness, durability, and corrosion resistance. These qualities make it an excellent material for producing knives that must deliver both performance and longevity.

One of the key advantages of SUS410 stainless steel plate is its ability to achieve high hardness through heat treatment. After quenching and tempering, the steel can reach a hardness of HRC 35–45, giving knives the sharp edge retention needed for precision cutting. At the same time, its wear resistance ensures that the blade withstands repeated use without rapid dulling or damage.

Another benefit lies in its corrosion resistance. While SUS410 stainless steel plate does not offer the same level of protection as austenitic stainless steels like SUS304, its chromium content (11.5–13.5%) provides sufficient resistance to rust in common kitchen and outdoor environments. This makes knives easier to maintain and more reliable for long-term use.

In addition, SUS410 stainless steel plate offers cost-effectiveness. It provides a strong performance-to-price ratio, allowing manufacturers to produce durable, high-quality knives without the higher costs associated with premium stainless steels.

In conclusion, the unique combination of hardness, wear resistance, and corrosion protection gives SUS410 stainless steel plate a clear advantage in knife manufacturing. It ensures blades remain sharp, durable, and practical—qualities that end users consistently value.
