8407 ESR Steel: A Buyer’s Guide to Properties, Applications, and Equivalent Grades
8407 ESR steel is a premium remelted hot-work tool steel used for dies, molds, and tooling exposed to heat, pressure, and repeated thermal cycling. It is commonly associated with the H13 tool-steel family, with equivalent or comparable designations often including AISI H13, DIN 1.2344, JIS SKD61, and China’s 4Cr5MoSiV1. These grades are useful starting points for comparison, not automatic one-to-one substitutes: chemistry, remelting route, heat treatment, and product specifications can differ.

This guide explains what buyers should verify before specifying or sourcing 8407 ESR steel. We cover its typical properties and uses, how to assess grade equivalents, and the practical questions to ask a supplier about condition, dimensions, documentation, price, and lead time.
Key Takeaways
- 8407 ESR is a hot-work tool steel, not a stainless steel grade.
- Its ESR processing can support improved cleanliness and structural consistency, but actual results depend on the producer, product size, and quality controls.
- H13, 1.2344, SKD61, and 4Cr5MoSiV1 are commonly used comparison grades; confirm the applicable standard and chemistry before substitution.
- Specify the application, required condition, dimensions, and documentation when requesting a quotation.
Who This Guide Is For
This guide is intended for procurement teams, toolmakers, mold manufacturers, and engineers evaluating hot-work tool steel. It is especially relevant when a drawing, existing tool, or supplier quotation names 8407 ESR but does not explain the material condition or equivalent-grade requirements. It can also help buyers compare offers from different regions without assuming that similar grade names guarantee identical performance.
What Is 8407 ESR Steel?
Grade and production context
8407 is a commercial designation used for hot-work tool steel associated with the H13 family. ESR means electroslag remelting, a secondary refining process in which an electrode is remelted through a slag layer. The process is used to improve ingot cleanliness and material uniformity; the degree of improvement should be assessed through the supplier’s process information and the documentation for the specific product.
The term “ESR” describes a production route, not a separate universal chemical composition. Two products called 8407 ESR may differ in specification, melt practice, delivery condition, or heat-treatment history. For that reason, buyers should obtain the producer’s grade designation and material certificate rather than relying on the name alone.
Typical properties and composition context
H13-family steels are alloyed to balance hot strength, toughness, hardenability, and resistance to thermal fatigue. As a comparison reference only, commonly published H13 chemistry ranges include carbon at 0.32–0.45 wt%, chromium at 4.75–5.50 wt%, and molybdenum at 1.10–1.75 wt%. These are general H13 ranges, not a guaranteed specification for every 8407 ESR product; confirm the actual limits against the supplier’s datasheet and purchase specification.
In service, performance depends on more than the grade label. Tool geometry, working temperature, cooling design, surface treatment, heat treatment, and operating cycle all affect service behavior. Request property data for the relevant size and condition, and avoid treating a typical catalog value as a guaranteed result for an unverified heat or section.
Applications and Material Options
Buyers commonly evaluate 8407 ESR for hot-work applications where tooling repeatedly contacts heated material or experiences rapid temperature changes. Potential uses include die-casting dies, hot-forging dies, extrusion tooling, and selected plastic-mold components where the design and processing conditions suit a hot-work tool steel. The correct choice depends on the actual thermal and mechanical loading, not simply the industry or tool name.
Available forms may include round or flat bar, blocks, and other semi-finished shapes, depending on supplier inventory and production capability. Products may be supplied in an annealed or otherwise specified condition for machining, while hardened and tempered material may be available for particular requirements. Confirm the requested form, dimensional tolerances, surface condition, and delivery state at quotation stage.

Equivalent Grades: How to Compare Them
AISI H13, DIN 1.2344, JIS SKD61, and GB 4Cr5MoSiV1 are commonly referenced as equivalents or close comparisons to the H13 family. Their broad application areas overlap, but designation alone does not establish identical chemistry, cleanliness, mechanical properties, or acceptance criteria. ESR is an additional process requirement that should be stated separately if it is important to the application.
| Designation | How buyers commonly use it | What to verify |
|---|---|---|
| 8407 ESR | Commercial H13-family hot-work steel designation with ESR route specified | Producer specification, chemistry, remelting route, condition, and certificate |
| AISI H13 | Common international comparison designation for hot-work tool steel | Applicable standard edition, chemistry limits, and required product quality |
| DIN 1.2344 / JIS SKD61 | Regional designations often compared with H13-family steel | Grade-specific requirements and whether the requested ESR processing is included |
| GB 4Cr5MoSiV1 | Chinese designation frequently used for an H13-type hot-work steel | Applicable national standard, actual composition, and acceptance conditions |
When substituting one designation for another, compare the governing standard and the material certificate line by line. If the tool is safety-critical or has a costly failure consequence, obtain engineering approval before changing grades or suppliers. A commercial equivalent statement is a useful screening tool, not a replacement for a specification review.
A Practical Selection Framework
- Describe the duty. Share the process, contact material, operating environment, thermal cycling, and expected tool life target if defined.
- Set the grade requirement. State whether 8407 ESR is mandatory or whether a documented H13-family alternative can be considered.
- Specify product details. Provide shape, finished or stock dimensions, tolerances, surface requirements, and delivery condition.
- Align heat treatment. Confirm whether the material is supplied annealed, hardened and tempered, or in another agreed condition. Establish who is responsible for subsequent heat treatment.
- Define acceptance documents. Request the material certificate and specify any required inspection, traceability, or additional quality records before placing the order.
Common buying mistakes
A frequent mistake is ordering by “H13 equivalent” without defining the required remelting route or standard. Another is comparing prices for different delivery conditions, sizes, or inspection scopes as if they were identical products. Buyers can reduce ambiguity by putting the grade, ESR requirement, dimensions, condition, documentation, and packing instructions on the same request for quotation.
Pricing, MOQ, and Lead Time
Price for 8407 ESR depends on factors such as section size, shape, quantity, processing route, delivery condition, machining allowance, and requested documentation. Minimum order quantities and lead times vary with stock availability and whether the supplier needs to source or produce the requested size. We recommend requesting a written quotation that separates material cost, processing or cutting charges, delivery terms, and any inspection requirements.
To support an accurate offer, provide the required dimensions and quantity in clear units, the destination country, and the target delivery schedule. If the size is flexible, tell the supplier which dimensions or delivery dates can be adjusted. This allows suppliers to identify practical stock alternatives without silently changing the grade or condition.
Supplier Evaluation Checklist
Before purchase, confirm that the supplier can identify the actual producer and product designation, explain whether ESR is included, and provide documentation matching the shipped material. Check that the quotation clearly states size, tolerance, delivery condition, quantity, packing, and delivery terms. For technically demanding tools, discuss the application with the supplier and your heat-treatment or tooling team before approving a substitute.
At Mingchuan, we support B2B buyers evaluating 8407 ESR and related hot-work tool steels by reviewing the requested grade, dimensions, condition, and documentation needs before quotation. Share your drawing or material specification where available, along with the intended application and quantity. We can then confirm what supply options are available and identify any points that should be clarified before an order is placed.
Conclusion: Choosing 8407 ESR with Confidence
8407 ESR is a hot-work tool-steel option commonly associated with the H13 family and used for tooling exposed to heat and repeated thermal cycles. H13, 1.2344, SKD61, and 4Cr5MoSiV1 can serve as comparison designations, but buyers should verify the exact standard, chemistry, ESR route, and condition rather than assume direct interchangeability. The best next step is to prepare a complete specification covering application, dimensions, delivery state, acceptance documents, and quantity.
