SKD61 is a chromium-molybdenum-vanadium hot-work tool steel used for dies and tooling exposed to heat, pressure, and repeated thermal cycling. When buying SKD61 steel, confirm the applicable standard and equivalent-grade requirements, supply condition, dimensions, heat-treatment needs, and inspection documents before comparing quotations. Mingchuan can review these details with B2B buyers to help identify a suitable material and supply format for their application.
This guide is intended for procurement teams, toolmakers, die designers, and manufacturers sourcing SKD61 steel for production or maintenance. It is useful if you are comparing material offers, checking whether an alternative grade is acceptable, or preparing a purchase specification. The information is general guidance, not a substitute for the governing standard, approved drawing, or a qualified heat-treatment procedure.
Buyers should involve engineering or quality personnel when material selection affects tool life, safety, or a validated manufacturing process. The correct choice depends on operating temperature, loading, cooling, tool geometry, and required service life. Sharing these conditions with a supplier can make a quotation more useful than requesting a price by grade name alone.
SKD61 is a JIS designation for hot-work tool steel. It is selected for tooling that must retain useful strength at elevated temperatures and tolerate repeated heating and cooling. The alloy’s chromium, molybdenum, and vanadium content contributes to its hot-work characteristics, while its final performance also depends on steelmaking quality, section size, heat treatment, and service conditions.
SKD61 is commonly compared with AISI H13 and related designations used in other standards. These grades are often treated as corresponding materials for sourcing discussions, but a name-to-name match does not prove that every chemistry limit, cleanliness requirement, or delivery condition is identical. Ask the supplier to identify the standard and provide the material documentation required by your project.
As a general reference, commonly published SKD61 composition ranges include carbon at 0.32–0.42 wt%, chromium at 4.5–5.5 wt%, and molybdenum at 1.0–1.5 wt%. These figures are reference ranges, not a certificate for a particular heat of steel. The applicable standard edition and the supplier’s inspection documents should govern acceptance.
SKD61 may be offered in different product forms and conditions, such as hot-rolled, forged, annealed, or machined stock, depending on the supplier and order requirements. Annealed material is commonly selected for machining before hardening, while pre-hardened or heat-treated supply may suit particular repair or production needs. Availability and suitability should be checked for the required dimensions and application rather than assumed from the grade name.
| Purchase item | What to confirm |
|---|---|
| Grade and standard | SKD61 designation, applicable standard, and any approved equivalent requirements |
| Product form | Bar, plate, block, or other requested form, plus the required dimensions |
| Supply condition | Annealed, heat-treated, or another agreed condition, with hardness requirements if applicable |
| Quality documentation | Required inspection certificate, heat number traceability, and agreed inspection scope |
| Processing needs | Machining allowance, surface condition, cutting requirements, and any special testing |
Heat-treatment figures should be treated as process references, not universal instructions. SKD61 is often austenitized in the approximate range of 1,000–1,050°C, but the correct cycle depends on the steelmaker’s guidance, section size, furnace control, quenching method, and target properties. A qualified heat treater should set the process and verify results against the tooling specification.
SKD61 is commonly considered for aluminum and other non-ferrous die-casting dies, hot-extrusion tooling, forging dies, and hot-work punches or inserts. In these applications, tooling may face thermal fatigue, abrasive or erosive wear, mechanical loading, and temperature variation. The dominant failure mode matters: selecting solely for a broad category such as “hot-work steel” may overlook the actual operating challenge.

For die-casting tooling, review the metal being cast, cycle conditions, cooling layout, surface treatment, and expected repair strategy. For extrusion dies, consider billet material, contact temperature, pressure, and the tooling geometry. For forging applications, assess impact loading, die size, preheating practice, and maintenance intervals with the engineering team.
SKD61 is not automatically the best choice for every tool exposed to heat. Severe corrosion, unusual wear, very high impact, or a specialized production process may require another grade or a modified design. Where a material change is proposed, confirm compatibility through engineering review and, where appropriate, controlled trials.
Clear requirements reduce the risk of receiving material that technically carries the requested grade name but does not match the project’s needs. If the specification is not finalized, provide the supplier with the drawing or a concise requirement sheet and ask which items need engineering confirmation. Keep any proposed substitutions subject to written approval by the responsible buyer or engineer.
The price of SKD61 steel depends on factors such as product form, dimensions, order quantity, supply condition, processing, inspection scope, and delivery destination. There is no reliable universal price or minimum order quantity that applies to every size and sourcing arrangement. Request a quotation using a complete specification so that offers can be compared on the same basis.
Lead time can also vary with stock availability, processing requirements, quantity, and shipping arrangements. Ask the supplier to distinguish material preparation time from transit time and to confirm the validity period of the offer. If your project has a fixed schedule, state the required delivery date early and ask whether the requested dimensions and condition can be supported.
Do not treat a generic product description as proof of conformance. Before placing an order, align the purchase order, technical specification, and supplier quotation, including any agreed inspection or documentation requirements. This is especially important when material is being substituted for an existing grade or used in a validated production process.
SKD61 is a widely used hot-work tool steel for applications such as die casting, extrusion, and forging, but the right purchase depends on more than the grade designation. Confirm the governing standard, application, product form, dimensions, supply condition, inspection documents, and delivery needs before selecting an offer. For a sound sourcing decision, have engineering review any equivalence or heat-treatment assumptions.
To request SKD61 steel from Mingchuan, provide your required grade or accepted equivalents, dimensions, quantity, condition, documentation needs, and destination. Include the tooling application and target delivery schedule if known. Mingchuan can use those details to review the supply request and prepare a quotation for your B2B evaluation.
