1.2344 hot work steel is a chromium-molybdenum-vanadium tool steel used for tooling exposed to elevated temperatures, repeated heating and cooling, and mechanical stress. It is commonly associated with the European grade X40CrMoV5-1 and is broadly comparable to AISI H13, although buyers should confirm the applicable standard and product specification rather than assume the grades are identical. Its balance of hot strength, toughness, and resistance to thermal fatigue makes it a candidate for die casting, forging, and extrusion tools. This guide explains how to evaluate its properties, formats, specifications, and supplier information before placing an order.
This guide is intended for purchasing teams, toolmakers, engineers, and manufacturers assessing steel for hot-work tooling. It is useful when comparing material grades, requesting quotations, or checking whether a supplier’s documentation matches a project’s technical requirements. It is not a substitute for design review or a material-specific heat-treatment procedure. For critical tooling, buyers should have the grade and processing route confirmed by their engineering and quality teams.
1.2344 is a hot-work tool steel whose alloy design includes chromium, molybdenum, and vanadium. These elements contribute to properties used in tooling that experiences heat and cyclic loading, while the steel’s performance also depends on its heat treatment, section size, cleanliness, and manufacturing history. The material is supplied in forms such as round bar, flat bar, and blocks, subject to a producer’s product range and stock. It is a tool steel, not a stainless steel; its chromium content does not make it corrosion-proof.
A commonly cited composition range for 1.2344 includes approximately 0.39–0.42% carbon, 4.8–5.5% chromium, 1.2–1.5% molybdenum, and 0.9–1.1% vanadium by mass. These figures are typical reference ranges, not a substitute for the chemistry limits in the standard specified on a purchase order. Silicon and other elements are also controlled, and limits can vary with the governing specification. Ask for the mill test certificate and check that its grade designation and reported chemistry match the order.
Buyers may encounter 1.2344, X40CrMoV5-1, and H13 in catalogs or supplier discussions. These names indicate closely related grade families, but equivalence should be confirmed against the required standard, chemical composition, and delivery condition. If a drawing names a specific standard or national designation, do not approve a substitution based only on a shared trade description. Document any proposed equivalent and obtain engineering approval before procurement.
In hot-work service, tooling can experience temperature changes, contact pressure, abrasion, and repeated impact. 1.2344 is selected in part because its alloy system is intended for hot-work applications that need a combination of strength at elevated temperatures and toughness. Resistance to thermal fatigue and wear is not a fixed guarantee: actual service life depends on tool geometry, operating conditions, surface treatment, cooling, and heat-treatment quality. Buyers should treat grade selection as one part of a complete tooling solution.
Heat treatment is especially important because it affects the material’s final hardness and toughness. A commonly referenced hardening temperature range for 1.2344 is about 1,000–1,030°C, but the correct cycle depends on the product, section, furnace practice, and supplier or heat-treatment specialist’s instructions. Tempering conditions also need to be specified for the intended application. Do not use a generic temperature range as a production procedure without technical confirmation.
These are common application categories, not a guarantee that 1.2344 is suitable for every tool in them. For example, a tool facing unusually severe wear, corrosion, or thermal shock may require a different grade, surface treatment, or tool design. Share the working temperature, load type, production cycle, and failure history with your material supplier or heat-treatment partner. That context makes a grade recommendation more useful than a request based only on the application name.

When sourcing 1.2344, specify more than the grade name. Product form, dimensions, delivery condition, standard, and inspection documentation can all affect suitability and processing. Depending on availability, a buyer may request annealed stock for machining or material supplied in another agreed condition. The chosen condition should align with the machining plan and the required downstream heat treatment.
| Specification item | What to confirm |
|---|---|
| Grade and standard | 1.2344 / X40CrMoV5-1 designation, applicable standard, and any approved equivalent |
| Product form and size | Round, flat, or block form; finished dimensions; and dimensional tolerances |
| Delivery condition | Annealed or other agreed condition, with any requested hardness requirements clearly stated |
| Quality documentation | Mill test certificate, heat or batch traceability, and any agreed inspection requirements |
| Processing requirements | Machining allowance, heat-treatment plan, surface condition, and packaging needs |
This approach helps prevent a common procurement problem: ordering the correct grade name in a form or condition that does not fit the manufacturing plan. The buyer should also consider the finished tool’s geometry and the amount of stock removed during machining. If several suppliers quote, compare the same specification line by line rather than comparing price alone. Any technical deviation should be visible and approved before production.
The price of 1.2344 depends on factors such as dimensions, product form, quantity, delivery condition, processing, inspection, and market availability. Minimum order quantities and lead times are supplier- and order-specific, so they should be confirmed in a written quotation rather than assumed from a catalog listing. Custom cutting or additional documentation may also affect the offer and schedule. To improve quotation accuracy, provide the grade standard, size, quantity, required condition, delivery destination, and target delivery date.
For total-cost review, compare material utilization and the processing route as well as the unit price. A readily available size may reduce waiting time or machining waste, while a custom size may require additional production planning. These are project-dependent trade-offs, not guaranteed savings. Request that the supplier identify any exclusions, substitutions, or unconfirmed delivery assumptions in the quotation.
Before placing an order, confirm that the supplier can identify the material grade and state the product form and delivery condition being quoted. Ask what documentation will accompany the shipment, including whether a mill test certificate and heat or batch traceability are available for the order. Check how dimensions, tolerances, packaging, and any agreed inspection requirements will be recorded. Clear written answers reduce ambiguity between procurement, production, and quality teams.
Also assess the supplier’s ability to support practical technical communication. A capable sourcing partner should be able to clarify grade designations, discuss available sizes and conditions, and flag information still needed to prepare a complete quotation. Do not treat a general capability statement as proof of a specific inspection or performance result. Confirm project-specific requirements in writing before order acceptance.
1.2344 hot work steel is a commonly used option for tooling exposed to elevated temperatures and cyclic mechanical demands, including die casting, forging, and extrusion applications. Its suitability depends on the exact grade specification, product condition, geometry, heat treatment, and operating environment; it is not a universal solution or a stainless steel. To move forward, verify the required standard, define the size and delivery condition, and specify documentation and inspection needs.
