1.2738 mold steel

1.2738 is a very common German standard plastic mold steel, usually referred to as 738 for short.

Performance characteristics

① Excellent polishing and photoetching performance;

②Good machining performance;

③ High purity and uniformity;

④ Uniform hardness;

⑤ Follow-up nitriding treatment or local flame quenching can be used to improve surface strength and surface wear resistance and reduce surface failure.

Compared with the traditional plastic mold steel P20, 1% nickel is added to OT718, which has better toughness and hardenability, and performs better in molds with large cross-section sizes. This type of steel is suitable for large-scale, especially thicker than 400mm, plastic molds that require uniform hardness, high toughness, and good surface polishing performance, such as TV frames and back shells, copier cases, bumpers, shock absorbers, instrument panels, etc. Large molds, as well as trash can molds, die-casting mold holders, etc.
