SKD61 is a Japanese-designation hot-work tool steel commonly selected for dies, molds, and tooling exposed to heat, pressure, and repeated thermal cycling. When buying SKD61 steel, confirm the applicable standard and grade, the required shape and finished dimensions, the delivery condition, and the documentation you need. SKD61 is a tool steel, not a stainless steel; its chromium content does not make it stainless. At Mingchuan, we help B2B buyers clarify these details before requesting a quotation, so the offered material can be assessed against the actual application.
This guide is for procurement teams, mold and die makers, machine shops, and manufacturers sourcing SKD61 for production or maintenance. It is also useful if you are comparing supplier quotations and need to understand why two offers may differ in condition, size, or included services. The information below is a purchasing framework, not a substitute for the governing material standard or your engineering specification. Confirm critical requirements with your technical team before placing an order.
SKD61 is a hot-work tool steel designation associated with Japanese standards. It is used for tooling that must retain useful strength at elevated temperatures and withstand thermal and mechanical stress. Typical applications include die-casting dies, hot-forging dies, extrusion tooling, and related mold components, subject to the operating conditions and design of each part.
Buyers often compare SKD61 with AISI H13 and other H13-type grades. These materials are commonly treated as close counterparts, but a name-to-name match does not guarantee identical chemistry, processing, or acceptance criteria. Ask the supplier to identify the standard and grade stated on the material documentation, then compare that information with the drawing or purchase specification.
For an order, specify the grade as SKD61 and name the standard or technical specification you require. A typical SKD61 chemistry reference includes carbon around 0.35–0.42%, chromium around 4.80–5.50%, molybdenum around 1.00–1.50%, and vanadium around 0.80–1.15%. These are indicative ranges, not a substitute for the applicable standard or a heat-specific material test certificate; verify the exact limits for your order.
If your tooling design was originally written for H13, ask engineering and the supplier to review the required chemistry, properties, and heat-treatment procedure before substituting SKD61. This is particularly important for critical dies or components with defined performance and inspection criteria. Do not rely on a grade label alone when the specification calls for a particular standard or test.
SKD61 may be sourced in forms such as round bar, flat bar, plate, or cut-to-size stock, depending on the supplier’s supply program and current availability. Provide the required thickness, width, length, diameter, and quantity, and state whether the dimensions are raw stock sizes or finished dimensions. Include tolerances and machining allowance when these affect fit, yield, or the production schedule.
There is no single universal size range that applies to every supplier or order. Large cross-sections, unusual dimensions, and special cutting requirements may need separate availability confirmation. For a useful quotation, send a drawing or a clear size list rather than relying on a general request for “SKD61 steel for sale.”
Common supply discussions distinguish between annealed stock for machining and material supplied in a hardened or otherwise processed condition. The appropriate condition depends on the component, the machining sequence, and the heat treatment planned by the buyer. As a general reference, annealed SKD61 is often listed at about 229 HB maximum, while hardened working hardness is frequently selected in the approximate range of 48–52 HRC; confirm the applicable specification and the intended treatment with your heat treater.

These figures are reference points, not a promise that every supplied piece will meet a particular value. Ask whether hardness is guaranteed, where it is measured, and whether the requirement applies before or after heat treatment. If you need a specific condition, put it in the purchase specification and request written confirmation.
For a die-casting tool, consider thermal cycling, contact with molten metal, cooling practices, and the size of the die. For forging or extrusion tooling, review the process temperature, pressure, tool geometry, and expected maintenance interval with your engineering team. The right grade and condition depend on the whole tooling system, not just the steel designation.
Machinability and heat-treatment planning also affect the buying decision. Annealed stock is commonly chosen when substantial machining is required before hardening, while pre-hardened or specially processed material may suit different production needs if available and specified. Discuss the sequence with the supplier and heat treater so that stock dimensions, machining allowance, and final requirements align.
Not every supplier includes the same services or documents as standard, so make these requirements explicit before comparing quotations. If a specification is incomplete, ask questions before approval rather than assuming that a quoted grade automatically includes the required condition, tolerances, or inspection. Keep the final agreed details in the purchase order.
SKD61 pricing can vary with size, quantity, supply condition, processing, documentation requirements, and market availability. Minimum order quantities, cutting charges, and transport terms also vary by supplier and destination. For that reason, a reliable quotation should be based on your actual size list and delivery requirements rather than a generic price per kilogram.
Lead time should be confirmed for the specific order. Stock availability, production requirements, additional processing, and inspection can all affect the schedule, so request an estimated dispatch date and clarify what events could change it. If your project has a fixed deadline, include it in the inquiry and ask the supplier to confirm whether the requested dimensions and condition can be supplied in time.
At Mingchuan, we support B2B inquiries by reviewing the requested grade, dimensions, condition, and order details with the buyer. Availability, processing options, documentation, minimum quantities, and delivery timing should be confirmed against the individual inquiry rather than assumed. Providing a drawing, quantity, destination, and technical specification helps us assess the request and prepare a more relevant quotation.
SKD61 is a hot-work tool steel used for tooling applications where elevated temperature and mechanical stress are relevant; it is not stainless steel. Before buying, confirm the grade and standard, dimensions, delivery condition, hardness or inspection requirements, and the documents needed for acceptance. Treat comparisons with H13 as a starting point for technical review, not automatic proof of interchangeability.
To move forward, prepare a size list or drawing, state your application and required delivery date, and send your preferred supply condition and documentation requirements to Mingchuan for review. We can then confirm the order-specific supply details and provide a quotation for your SKD61 steel inquiry.
