High rust resistance: It has rust resistance comparable to SUS420J2 and can effectively solve the rust problem of NAK80 and H13.
High mirror finish: achieved good purity through special melting, with mirror finish equivalent to NAK80.
High toughness: it can effectively solve the problems of corner cracking and stress corrosion cracking of water-cooling holes of the mold.
Performance comparison
(* 1) Hardness is the hardness at the time of use. Quenched and tempered materials (PAT868S, S-STAR-A) can also have low hardness.
(* 2) The drilling process of NAK86K may encounter difficult cutting situations, and special attention should be paid when conducting hole drilling.
(* 3) There may be machining deformation, and machining allowance needs to be reserved during rough machining.
