What is a highly competitive, corrosion-resistant mold material that can replace NAK80?

Datong Special Steel NAK86K / Datong Special Steel Co., Ltd.

Preventing Rust and Cracks in NAK80 Molds

・Improved corrosion resistance makes it effective for preventing rust on NAK80 molds

・High toughness at molding temperatures makes it effective for preventing cracks in NAK80 molds

・Mirror finish equivalent to that of NAK80

・As a pre-hardened steel, it can be machined directly without further heat treatment

・Can be further hardened through nitriding treatment

・Automotive components (lights, grilles, panels)

・Cosmetic containers, food containers, medical devices

・For headlight molds, improved rust resistance has reduced the frequency of maintenance required due to rust.

・Thanks to high corrosion resistance, medical molding—typically performed in cleanrooms—can now be produced overseas.

・Improved toughness has reduced the occurrence of mold fractures and cracks, extending mold life.

・Hardness has improved from NAK80 HV1000 to NAK86K HV1200 through nitriding treatment.
