Pre-hardened steel is a generic term for heat-treated steel bars such as induction-hardened special steel and the like.
Neturen’s pre-hardened steel can shorten lead time and reduce labor-hours since straightening and finish polishing prior to use are not required

Features of Neturen’s Pre-hardened Steel (Patented)

(1) No need for straightening (Excellent straightness is retained)

Example: SUS440C φ2.0 × 2200L Warpage 100 μm or less

(2) No need for finish polishing (Neturen already polishes it with centerless grinding)

Example: AISI4150, Circularity 2 μm or better

(3) Abe to reduce grinding allowance (almost free from surface decarburized layer and oxide scale generation)

Even in the case of material with heavy thermal warpage or small-diameter wire, we can manufacture products that stay straight.

Thanks to Neturen’s integrated manufacturing process from material procurement to fixed-length cutting process, we deliver products in almost complete condition. We can also manufacture fully quenched steel or hollow parts, so please feel free to contact us about your needs.
