Delivery Condition

 

Steel will be processed in the best facilities: EAF+LF+VD. Delivered as hot rolled, the surface can be black or machined. It undergoes quenching and tempering, achieving remarkable hardness levels of 28-34HRC, or tailored to your exact requirements.

Hardness options include 30-36HRC or a custom range. Rest assured, our rigorous UT testing guarantees 100% pass rate.

 

Characteristics

1. Widely used plastic mold steel with excellent comprehensive mechanical properties, boasting superb mechanical properties and unmatched hardenability. It offers consistent hardness across large sections post-quenching and tempering.
2. It excels in polishing ability but low toughness.
3. Designed for immediate use after pre-hardening, ensuring reliable performance and minimizing deformation post-heat treatment, it's a standout choice for molds.

 

Applications

1. Ideal for crafting large plastic molds where precision and longevity are paramount.
2. Perfect for low melting-point alloyed die casting moulds such as those for Tin, Zinc, and Lead.
