Your Position: Home - Other Stainless Steel - 1.2344 hot work Steel Manufacturer Guide to Grades, Applications, and Supplier Selection
1.2344 is a chromium-molybdenum-vanadium hot-work tool steel commonly used for dies and tooling exposed to repeated heat, pressure, and thermal cycling. It is also widely associated with the H13 designation, although equivalence depends on the applicable standard and product requirements. Buyers should confirm the governing specification, steelmaking route, delivery condition, dimensions, and required inspection documents before placing an order. In this guide, we explain how to match the grade to an application and evaluate a 1.2344 hot work steel manufacturer or supplier.
You can find more information on our web, so please take a look.
This guide is intended for procurement teams, toolmakers, engineers, and manufacturers sourcing material for hot-work tooling. It is relevant whether you are buying a new tool-steel grade for a production program or qualifying an additional source for an established design. The information can also help buyers prepare a more complete request for quotation. For critical tooling, final material and heat-treatment decisions should be reviewed against the design, operating conditions, and applicable specifications.
1.2344 is a hot-work tool steel identified in European material designations and commonly compared with AISI H13. It contains chromium, molybdenum, and vanadium as principal alloying elements, alongside carbon and other constituents controlled by the relevant specification. This alloy design supports use in tools that experience elevated temperatures and repeated mechanical loading. It is not stainless steel, so buyers should not select it on the assumption that it provides stainless-grade corrosion resistance.
Buyers may encounter 1.2344, X40CrMoV5-1, and H13 in supplier catalogs or technical discussions. These names are often used to describe closely related grades, but they should not be treated as automatically interchangeable for every order. Chemistry limits, quality requirements, product dimensions, and acceptance criteria depend on the governing standard and purchase agreement. Ask the supplier to state the exact standard and grade on the quotation and material documentation.
| Buyer check | Why it matters |
|---|---|
| Grade and standard | Clarifies the specification used for chemistry and acceptance. |
| Product form and size | Confirms whether the stock can be processed into the required tool blank. |
| Delivery condition | Identifies the supplied hardness or processing state before machining. |
| Inspection documents | Defines what material traceability and test information will accompany the order. |
As a practical reference, commonly published 1.2344 chemistry ranges include approximately 0.37–0.42% carbon, 4.8–5.5% chromium, 1.2–1.5% molybdenum, and 0.85–1.15% vanadium. These figures are indicative rather than a substitute for the purchase specification, since permitted ranges can differ by standard and product requirement. Always check the supplier’s certificate against the exact grade and standard you ordered. If your design specifies a particular chemistry range or steelmaking route, include it in the RFQ.
1.2344 is used in a range of hot-work tools, including die-casting dies, hot-forging dies, extrusion tooling, hot-shear blades, and other tooling exposed to heat and impact. Its suitability depends on the tool geometry, operating temperature, cooling practice, production cycle, and maintenance conditions. A grade that performs well in one process may not be the best choice for another. Ask your tool designer or heat-treatment provider to confirm the material selection for the intended duty.
Begin with the actual failure mode or design requirement, rather than choosing a grade from its name alone. For example, a tool facing thermal cycling may need careful consideration of thermal-fatigue resistance and cooling design, while impact-loaded tooling also requires attention to toughness and section size. For machining and heat treatment, the initial delivery condition and the supplier’s processing recommendations matter as well. Share operating details with the supplier so that recommendations are tied to the application rather than made in isolation.

Other hot-work grades may be considered when the operating conditions or property priorities differ. However, a substitution should be assessed against the relevant standard, tool design, heat-treatment route, and service conditions. Do not assume that a nominally similar grade will produce the same tool life or processing results. If you are changing grade, document the reason and obtain technical review before production use.
State the grade, standard, product form, dimensions, quantity, and required delivery condition in the RFQ. Include any requirements for surface condition, dimensional tolerances, ultrasonic examination, or other inspections where applicable. If these details are not fixed, ask suppliers to identify their assumptions in the quotation. Clear requirements make offers easier to compare and reduce the risk of receiving material that is unsuitable for machining or heat treatment.
Ask what documentation is supplied with the material and how the product is linked to its heat or batch. Confirm which chemical analysis and test results are available, and whether the inspection scope matches your purchase requirements. Do not assume that a certificate, test, or third-party inspection is included unless the supplier confirms it in writing. For projects with specific compliance needs, agree on documentation and acceptance criteria before production begins.
Discuss the intended machining, heat treatment, and finishing route with the supplier or your qualified processing partner. Ask whether the supplier can provide product data and recommendations for the supplied condition, while treating any suggested process as guidance to be validated for the tool and equipment. For example, hardening and tempering parameters should be chosen from the applicable technical information and verified against section size and required properties. Avoid applying a generic cycle without confirming that it suits the material and component.
Price is only one part of the sourcing decision. Compare the quoted product form, usable yield, packaging, delivery basis, inspection scope, and any cutting or processing services. Minimum order quantities and lead times vary with stock availability, dimensions, production planning, and export arrangements, so request a current written estimate rather than relying on a general range. Clarify how substitutions, split shipments, and changes to order quantities will be handled.
At Mingchuan, we support B2B buyers evaluating hot-work steel requirements by discussing grade designation, product form, dimensions, and order documentation. Because availability and processing options depend on the requested specification and stock situation, we confirm these details for each inquiry rather than making a blanket commitment. To help us assess your request, provide the required standard, dimensions, quantity, delivery condition, and any inspection or documentation needs. If you are replacing an existing supply source, include the current specification so we can identify the points that need confirmation.
1.2344 is a widely used hot-work tool steel for applications such as die casting, forging, extrusion, and hot shearing, but successful sourcing depends on more than the grade name. Confirm the exact standard, product condition, dimensions, inspection scope, and service requirements before choosing a supplier. Then compare quotations on a like-for-like basis, including documentation, delivery, and any agreed technical support. Send Mingchuan your specification and application details to request a quotation and confirm the options available for your project.
