Manufacturing Excellence

Our large mold steel inventory includes 718H blocks in standard and custom sizes from certified European and Japanese mills. We machine 718H directly in its pre-hardened state, eliminating the risk of distortion from post-machining heat treatment. This makes 718H our recommended choice for large automotive molds where dimensional stability and cost efficiency are paramount.

Frequently Asked Questions

Q: What is the advantage of 718H over through-hardened steels?

A: 718H is supplied pre-hardened (33-38 HRC), so we machine it directly without heat treatment. This eliminates heat treatment distortion, reduces lead time by 5-7 days, and ensures the mold maintains its machined accuracy.

Q: Is 718H suitable for large automotive molds?

A: Yes. 718H is the industry standard for large automotive interior and exterior trim molds, combining good hardness with excellent machinability and toughness.

Q: Can 718H molds be repaired or modified?

A: Yes. 718H is weldable and machinable, making it easy to repair or modify molds during their service life without special heat treatment procedures.

Q: How does 718H compare to P20?

A: 718H is a premium version of P20 with improved hardenability, better polishability, and more uniform hardness through thicker sections, making it ideal for medium to large molds.
