SKD61 is a hot-work tool steel commonly selected for dies, molds, and tooling exposed to elevated temperatures, repeated heating, and mechanical stress. When sourcing it, confirm the governing standard, steel condition, dimensions, and inspection documents rather than relying on the grade name alone. SKD61 is often compared with AISI H13 and EN 1.2344, but these designations should not be treated as automatically interchangeable without checking the applicable requirements. Mingchuan can discuss SKD61 sourcing needs, available forms, and quotation details with buyers preparing a specification.
This guide is for mold makers, die manufacturers, machine shops, purchasing teams, and industrial distributors evaluating SKD61 steel. It is useful when comparing supplier offers, converting a drawing requirement into a purchase specification, or deciding whether to buy stock for further machining. The information is general procurement guidance, not a substitute for a project-specific material standard or heat-treatment procedure. For critical tooling, have the steel grade and processing route reviewed by the responsible materials or tooling engineer.
SKD61 is a Japanese hot-work tool steel designation commonly associated with JIS material specifications. Its alloying elements support use in tooling that experiences heat and repeated thermal cycles, such as die-casting and hot-forming applications. The balance of properties in a finished tool depends not only on the grade but also on steelmaking quality, section size, heat treatment, and machining practice. Buyers should therefore request traceable material identification and confirm the delivery condition against their project requirements.
AISI H13 and EN 1.2344 are frequently used as comparison grades for SKD61 because they occupy a similar hot-work tool steel category. Their chemistry and specified requirements are close in common commercial practice, but details can differ between standards, revisions, and product specifications. If a drawing calls for one exact designation, ask the supplier to identify the standard printed on the material certificate and state whether any substitution is proposed. Do not approve a cross-grade substitution based only on a sales description saying “equivalent.”
SKD61 is a chromium-molybdenum-vanadium hot-work tool steel. Commonly published composition ranges for SKD61-type material include approximately 4.8–5.5% chromium and 1.2–1.5% molybdenum, but the controlling standard and mill certificate should determine acceptance. These figures are orientation points, not a replacement for checking a particular heat’s certified chemistry. Request the applicable standard and heat-specific documentation when chemical limits matter to your application.
| Specification item | What to clarify with the supplier |
|---|---|
| Grade and standard | SKD61 designation, governing standard, and any proposed equivalent |
| Supply condition | Annealed, pre-hardened, or another agreed condition; confirm hardness requirements if applicable |
| Product form | Round bar, flat bar, plate, block, or forged stock, subject to availability |
| Dimensions | Thickness, width, diameter, length, machining allowance, and tolerances |
| Quality documents | Material test certificate, heat or batch identification, and any agreed inspection records |
SKD61 may be sourced as round bar, flat bar, plate, or block, depending on supplier stock and production capabilities. Round bar can suit turned components and cylindrical tooling, while flat or block stock may reduce initial preparation for inserts, cores, and die components. The best form depends on the finished geometry, machining sequence, and required material orientation. Confirm actual dimensions and tolerances in the quotation because stock availability can vary by size and location.
Buyers commonly evaluate SKD61 for die-casting dies, extrusion tooling, hot stamping or forging components, and plastic mold parts that need heat resistance. The exact grade choice should reflect operating temperature, contact conditions, cooling method, loading, and expected maintenance strategy. A material suitable for one tool component may not be the most economical choice for every part in the same mold or die. Share the actual service conditions with your tooling or materials engineer before finalizing the grade.

Heat-treatment values should be treated as process-specific rather than universal grade guarantees. For orientation, published processing guidance for H13-type hot-work steel often places austenitizing in the approximate range of 1000–1030 °C, but the correct cycle depends on the product, section, equipment, and required properties. Do not use a generic temperature range as a production instruction without the material supplier’s or heat treater’s approved procedure. Request a recommendation tied to your exact stock size and final tooling requirements.
SKD61 pricing depends on factors such as product form, dimensions, quantity, steelmaking and processing route, machining requirements, documentation, and delivery destination. Minimum order quantities and lead times are supplier- and stock-specific, so they should be confirmed for the exact requested size rather than assumed from the grade name. For a useful quotation, send a drawing or size list, quantity per size, required condition, destination, and target delivery schedule. If your timing is flexible, ask whether available stock can meet the specification before requesting a made-to-order option.
A low price alone does not establish that material meets a tooling specification. Compare offers on the same grade, standard, condition, dimensions, documentation, and delivery basis. If an offer is unclear about any of these points, ask for written clarification before placing an order. This reduces the risk of receiving stock that requires unplanned processing or does not match the drawing.
One frequent mistake is treating SKD61 as stainless steel because the buyer works with stainless grades. SKD61 is a tool steel and should not be selected on the assumption that it provides stainless-steel corrosion resistance. Another mistake is ordering by grade name without specifying dimensions, condition, tolerances, or documentation. Buyers also create avoidable risk when they assume that H13 or 1.2344 substitutions are acceptable without engineering approval.
Mingchuan supports B2B buyers seeking SKD61 steel by discussing grade requirements, supply form, dimensions, and documentation needs during the quotation process. Share your drawing or specification, required quantity, delivery location, and any approval requirements so the request can be evaluated against available supply options. Where a requested size or condition needs confirmation, clarify it before order placement rather than relying on a general product description. This practical information helps both sides establish a clear scope for the offer.
To source SKD61 successfully, identify the governing grade standard, choose the right product form and condition, and define dimensions, tolerances, traceability, and delivery requirements. Treat H13 and 1.2344 as comparison designations that require confirmation against your specification, not automatic substitutes. Your next step is to prepare a drawing or size list and send it with the required quantity, destination, and documentation needs. Contact Mingchuan to discuss your SKD61 steel inquiry and request a quotation based on those details.
