Supply 8407 Steel Hot Work Tool Material Guide For B2b Buyers - China

What Is 8407 Steel? A Quick Overview for Procurement Teams

8407 steel is a premium-grade hot work tool steel, developed in Sweden (Uddeholm/ASSAB) and produced using electro-slag remelting (ESR) technology.

Chemically, it belongs to the H13 family, but its tightly controlled melting and purer microstructure give it a performance edge over conventionally melted H13 — particularly in thermal fatigue resistance, isotropy, and polishability .

For B2B buyers, the key takeaway is simple: 8407 steel is an "upgraded H13"— a material you specify when standard H13 dies fail early through heat checking, cracking, or dimensional drift, and when total tooling cost of ownership matters more than the per-kilogram price.

Key Properties That Drive Purchase Decisions

Thermal fatigue resistance

8407's headline advantage.

Repeated heating/cooling cycles in die casting and forging cause "heat checking" (network cracking).

8407's high purity and fine, uniform microstructure delay crack initiation significantly .

Isotropy (uniform properties in all directions)

ESR melting gives 8407 steel better isotropy than conventional H13, improving resistance to mechanical fatigue and thermal stress fatigue — critical for large dies and complex cavities .

Hardness headroom

8407 steel dies can typically run 1–2 HRC higher than standard H13 without losing toughness, and higher hardness directly slows heat checking and extends die life.
