If you are sourcing SKD61 tool steel, confirm three things before comparing quotations: the required material standard and condition, the product form and finished dimensions, and the documentation and processing support you need. SKD61 is a Japanese hot-work tool steel commonly compared with AISI H13, but equivalence should be confirmed against the applicable standard and mill certificate rather than assumed from the grade name alone. At Mingchuan, we help buyers define these requirements so that the quoted material is appropriate for the tool, machining plan, and delivery schedule.

This guide is for procurement teams, mold makers, die manufacturers, and engineering staff sourcing SKD61 for new tools or replacement stock. It is useful whether you are buying a single block for a trial tool or planning repeat orders across multiple dimensions. The aim is to make the specification clear enough for suppliers to quote comparable material and reduce avoidable delays.
SKD61 is a chromium-molybdenum-vanadium hot-work tool steel identified in Japanese standards. It is used where tooling is exposed to elevated temperatures, thermal cycling, pressure, or repeated contact with hot material. Typical applications include die-casting dies, hot forging dies, extrusion tooling, and other hot-work components; suitability depends on the tool design, operating conditions, heat treatment, and maintenance.
SKD61 is often described as comparable to AISI H13, but a grade comparison is not a substitute for checking the governing specification. Standards may differ in chemistry limits, manufacturing requirements, inspection, and acceptance criteria. If a drawing calls for a specific standard, ask the supplier to quote and document that standard rather than relying only on a familiar equivalent name.
Commonly published SKD61 composition limits include carbon at 0.35–0.42%, chromium at 4.80–5.50%, molybdenum at 1.00–1.50%, and vanadium at 0.80–1.20%. These figures are weight percentages and should be checked against the exact standard edition and the certificate supplied with the material. They are a useful screening reference, not proof that a particular batch meets your purchasing specification.
SKD61 is commonly sourced as round bar, flat bar, plate, or cut-to-size block, depending on mill availability and supplier inventory. Buyers may also request different delivery conditions, such as annealed stock for machining or a specified heat-treated condition. Availability, dimensions, and tolerances vary by supplier, production route, and order quantity, so include the exact requirement in your inquiry.
As examples of the level of detail needed for a quotation, a buyer might specify round bar at 80 mm diameter, flat stock at 100 × 100 mm, or a block at 500 mm length. These are illustrative order dimensions, not a claim about standard stock availability. State whether dimensions are in millimetres, identify permitted tolerances, and clarify if any machining allowance is required.
Begin with the tool’s working conditions rather than the material label alone. Identify the contact temperature, mechanical loading, cooling or lubrication practice, expected production cycle, and failure mode of the existing tool if it is a replacement. This information helps your supplier and heat-treatment partner assess whether SKD61 is an appropriate candidate and what delivery condition is practical.
For hot-work dies, resistance to thermal fatigue, wear, and cracking can be important, but performance is affected by more than the steel grade. Tool geometry, steel cleanliness, machining, heat treatment, surface condition, and operating practice all contribute. Where a tool is failing early, share photographs or a failure description and ask the engineering team to review the complete process rather than simply ordering a harder grade.
Write the full grade designation and required standard on the inquiry. Specify whether you need annealed stock for machining, a heat-treated product, or a particular hardness after treatment. If hardness is critical, state the target, test method, test location, and acceptance criteria; avoid using a general hardness value without aligning it with the tool design and supplier’s process.

List shape, dimensions, quantity, and unit of measure. Explain whether the dimensions are finished sizes or rough stock sizes, and include tolerances where they affect machining or assembly. For irregular or large components, a dimensioned drawing can prevent misunderstandings about orientation, cutting direction, or allowance.
Ask what documentation is available for the order, such as a material test certificate, heat or batch identification, and inspection records agreed in the purchase specification. Confirm that the certificate identifies the supplied material and that the required standard and chemistry are addressed. If you need ultrasonic testing, surface inspection, or additional testing, state the method and acceptance level before order confirmation; do not assume these are included by default.
Clarify whether cutting, machining, heat treatment, or other processing is included in the quotation. Confirm packaging, shipping destination, required delivery date, and the point at which lead time begins. These details help make offers comparable and reduce the risk that a low material price excludes services you need.
SKD61 pricing depends on factors such as dimensions, quantity, product form, material condition, processing, inspection requirements, and shipping arrangements. A supplier may have different minimum order quantities for stock sizes and custom production, so request the MOQ for the exact specification rather than assuming one fixed threshold. Lead time can also vary with inventory and any requested cutting, testing, or heat treatment.
For a useful comparison, ask each supplier to separate material cost, processing charges, inspection or documentation fees, packing, and freight where applicable. Confirm quotation validity and the delivery term, and ask whether substitutions or partial shipments require your approval. A clear quotation helps procurement evaluate total landed cost instead of comparing material price alone.
Use the following checklist when assessing an SKD61 supplier. A supplier’s ability to answer these questions clearly is often as important as the initial price, particularly when the material is tied to a tool build schedule.
At Mingchuan, we work with buyers to clarify grade designation, product form, dimensions, delivery condition, and documentation requirements before quotation. We can discuss the requested stock or cut size, identify information needed for a comparable offer, and confirm which processing or inspection options can be arranged for the order. Final availability and lead time depend on the specification, quantity, and shipping destination, so we confirm these details during the inquiry process.
To request a quotation, send the SKD61 standard or grade, product form, dimensions, quantity, required condition, and destination. Include a drawing or inspection requirement if applicable, and tell us your target delivery date. With those details, we can review the request and respond with the relevant supply and service options.
SKD61 is a hot-work tool steel commonly compared with AISI H13, but buyers should verify the exact standard, material condition, and certificate for each order. Select the form and dimensions around the tool design, machining plan, and acceptance requirements, then compare suppliers on documentation, processing, MOQ, lead time, and total delivered cost. To move forward, prepare a complete specification and share it with Mingchuan for a focused quotation and supply review.
