1.2344 is a chromium-molybdenum-vanadium hot work tool steel used for tooling exposed to heat, pressure, and repeated thermal cycling. It is commonly associated with the designation H13, although buyers should confirm the applicable standard and material certificate rather than assume every designation is interchangeable. When sourcing from a 1.2344 hot work steel manufacturer, specify the required standard, product form, dimensions, delivery condition, inspection documents, and any machining or heat-treatment requirements.

This guide explains how to identify the grade, match it to an application, and prepare a clear purchase specification. At Mingchuan, we work with B2B buyers to review these details and assess a supply request before quotation. Final availability, delivery condition, and documentation should be confirmed for each order.
This guide is intended for procurement teams, toolmakers, engineers, and distributors buying hot work steel for new tooling or replacement parts. It is especially useful when comparing offers from different suppliers or translating a drawing into a purchase order. Buyers working to a customer or industry specification should treat that specification as the controlling requirement.
1.2344 may be considered for tools used in processes such as aluminum or zinc die casting, hot forging, and hot extrusion. Suitability depends on the actual operating temperature, applied loads, cooling method, tool geometry, and production conditions. The grade alone cannot guarantee tool life or performance.
1.2344 is commonly identified by the European material number 1.2344 and the designation X40CrMoV5-1. H13 is a widely used designation for a comparable hot work tool steel. Because standards and permitted chemistry can differ, buyers should state the required standard in the enquiry and check the certificate accompanying the supplied material.
The grade contains chromium, molybdenum, and vanadium as key alloying elements. These elements contribute to properties valued in hot-work tooling, including resistance to softening at elevated temperature and the ability to be hardened and tempered. Actual performance also depends on steelmaking quality, section size, heat treatment, tool design, and use conditions.
The following ranges are commonly associated with 1.2344 specifications, but they are not a substitute for the buyer’s governing standard or the supplier’s certified analysis. Small differences may occur between standards and product requirements. Use the chemical composition reported on the material certificate for acceptance decisions.
| Element | Typical range by mass | Buyer consideration |
|---|---|---|
| Carbon (C) | 0.37–0.42% | Contributes to achievable hardness and strength after heat treatment. |
| Chromium (Cr) | 4.80–5.50% | Part of the alloy system supporting hot-work performance and hardenability. |
| Molybdenum (Mo) | 1.20–1.50% | Contributes to resistance to softening during elevated-temperature service. |
| Vanadium (V) | 0.90–1.10% | Forms hard carbides and is part of the grade’s wear-resistance profile. |
1.2344 is used for dies, inserts, punches, and related tooling where the working surface experiences elevated temperatures and mechanical stress. Typical application areas include die casting, hot forging, and extrusion tooling. These are common uses, not a blanket recommendation for every tool in those processes.
For a die-casting insert, buyers may need to consider thermal cycling, molten-metal contact, cooling channels, and surface treatment. For forging or extrusion tooling, compressive loading, wear, workpiece temperature, and tool geometry may be more central to the decision. Share operating details with the supplier or heat-treatment partner when selecting a condition and processing route.
Not every hot-work application calls for 1.2344. A different grade or a revised tool design may be worth evaluating when the main requirement is unusually high wear resistance, thermal fatigue resistance, toughness, or corrosion resistance. The best option depends on which failure mode is occurring and the specific working environment.

For replacement tooling, record the existing grade, failure location, service history, and any heat-treatment or surface-treatment details available. A substitution based only on a similar grade name can introduce avoidable risk. Where the original specification is unclear, request engineering review before changing material.
Start by naming the material designation and governing standard, then identify the product form, such as round bar, flat bar, or a cut-to-size block. State the required dimensions and tolerances, including whether dimensions refer to the supplied stock or finished component. Also specify the delivery condition, such as annealed, if required by your manufacturing route.
Heat-treatment needs should be stated separately from the steel grade. If the supplier is expected to provide heat treatment, define the required hardness or other acceptance criteria and clarify whether the requirement applies before or after machining. Do not rely on a generic hardness value when the drawing or process requires a specific condition.
Identify which documents your receiving process requires, such as a material test certificate, heat or batch traceability, or dimensional inspection records. If non-destructive testing, ultrasonic inspection, or special cleanliness requirements apply, describe the method and acceptance criteria in the enquiry. Requirements should be agreed before order confirmation, since they can affect availability, processing, and price.
For a clear supplier comparison, send the same technical specification to every bidder. Confirm how each offer treats tolerances, cutting, machining allowance, packaging, and delivery terms. A lower material price may not represent a lower total cost if important processing or inspection items are excluded.
There is no single reliable price or lead time for all 1.2344 orders. Quotation factors typically include product form, dimensions, quantity, delivery condition, processing, inspection scope, and shipping destination. Minimum order quantities and production or dispatch schedules depend on the requested specification and stock availability, so they should be confirmed in the quotation.
To help us assess a request, provide the grade and standard, a drawing or dimension list, quantity, required delivery condition, documentation requirements, and destination. If the order is time-sensitive, include the required arrival date and ask which items are available from stock versus made or processed to order. We can then review the request and clarify any details needed for a firm offer.
At Mingchuan, we support B2B enquiries for 1.2344 hot work steel by reviewing grade, dimensions, product form, and buyer-specific requirements before quotation. Share your drawing or specification along with quantity and delivery location so we can check the request and confirm the available supply route. Where requirements are incomplete, we will identify the details that need clarification rather than assume them.
1.2344 is a commonly used hot work tool steel for tooling exposed to elevated temperatures and repeated mechanical or thermal loading, with H13 serving as a frequent comparison designation. The right purchasing decision depends on more than the grade name: confirm the standard, application, product form, dimensions, delivery condition, inspection scope, and documentation. For your next step, prepare those details and request a quotation against one consistent specification.
