Understanding H13 Material: What is DIN 1.2344 Steel?
H13 steel is a versatile and widely used hot-work tool steel, categorized under the AISI (American Iron and Steel Institute) classification system. Its European equivalent, DIN 1.2344 material, shares the same essential properties and chemical composition, making the terms largely interchangeable in the global market.
The primary characteristic of H13 is its excellent combination of shock and abrasion resistance at both low and high temperatures. Its exceptional toughness and good red-hardness—the ability to retain its hardness at elevated temperatures—make it the go-to choice for a multitude of hot-working and cold-working applications.

Key features that define H13 / DIN 1.2344 material include:
-
High Toughness and Ductility: It can withstand significant impact and stress without fracturing.
-
Excellent Thermal Fatigue Resistance: It resists cracking initiated by cyclical heating and cooling, a common failure point in die-casting operations.
-
Good Machinability: Despite its toughness, H13 can be machined to precise tolerances with relative ease.
-
High-Level Hardenability: It can be through-hardened in large sections through air quenching.
-
Dimensional Stability: It maintains its shape and size well during heat treatment.
At Milano Special Steel, we offer standard H13 and an even higher grade: H13 ESR (Electro-Slag Remelted). The ESR process refines the steel, removing impurities and creating a more homogeneous, cleaner microstructure. This results in superior toughness, polishability, and performance, making it the premium choice for the most demanding applications like pressure die casting and high-performance plastic molds.
Chemical Composition: The Foundation of Performance
The remarkable properties of H13 material are a direct result of its carefully balanced chemical composition. As a top DIN 1.2344 material supplier, Milano Special Steel ensures that every batch meets stringent international standards for a perfect chemical makeup.
Here is a typical chemical composition for H13 / DIN 1.2344 Steel:

Applications: Where H13 material & DIN 1.2344 Material Excels
The versatility of H13 makes it indispensable across a wide range of industries. As a leading DIN 1.2344 material supplier, we provide steel that forms the backbone of modern manufacturing.
Aluminum and Pressure Die Casting
This is the primary application for H13 steel. The material’s high thermal fatigue strength and resistance to heat checking (cracking) make it ideal for creating dies, inserts, and core pins used in casting aluminum, zinc, and magnesium alloys. Its durability ensures a longer tool life, even under the intense pressure and temperature cycles of die casting.
Plastic Mold Steel
For high-volume injection molding, especially with abrasive or reinforced plastics, H13 is an excellent choice. Its high polishability (especially in ESR grade) and exceptional wear resistance ensure a flawless surface finish on molded parts and a long-lasting mold.
Forging Industries
H13 is widely used for forging dies, punches, and mandrels. Its ability to withstand repeated, heavy impacts at high temperatures is critical in press forging and hammer forging operations.
Extrusion Tooling
In the extrusion of aluminum and other non-ferrous metals, H13 is used to make dies and liners. The material must resist the intense heat and abrasive wear generated as the metal is forced through the die, and H13 performs this task admirably.
Sheet Metal Tooling
For trimming, punching, and forming operations on sheet metal, H13 provides a durable and long-lasting cutting edge. Its toughness prevents chipping and cracking, leading to cleaner cuts and reduced tool maintenance.
Automotive Industry
From engine components to structural parts, the automotive industry relies heavily on processes like die casting and forging. H13 is the material of choice for the tooling that produces these critical parts, ensuring precision, strength, and reliability.
Cutting Tool Manufacturing
While not a high-speed steel, H13’s toughness makes it suitable for manufacturing shear blades and knives used for hot and warm cutting applications.
The Heat Treatment Process: Unlocking H13’s Full Potential
To achieve its renowned properties, H13 material must undergo a precise heat treatment process. A knowledgeable H13 material supplier like Milano Special Steel can provide guidance on these critical steps.
-
Annealing: This process is performed to soften the steel for easier machining. It involves heating the material to approximately 870°C, holding it at that temperature, and then cooling it very slowly in the furnace.
-
Hardening (Austenitizing): This is the critical step for developing hardness. The steel is preheated in stages to minimize thermal shock and then heated to a final hardening temperature of 1010-1040°C. It is then “quenched” or rapidly cooled, typically in still air, which is why H13 is known as an “air-hardening” steel. This process transforms the internal structure into hard martensite.
-
Tempering: After hardening, the steel is extremely hard but also brittle. Tempering is essential to restore toughness. It involves reheating the hardened steel to a specific temperature (usually between 540-650°C), holding it for a set time (typically 2 hours minimum), and then cooling it. H13 is almost always double-tempered to ensure optimal toughness and dimensional stability. The final hardness is determined by the tempering temperature.
Proper heat treatment is paramount. An error in this process can compromise the tool’s performance and lead to premature failure. At Milano Special Steel, we provide material that responds predictably and reliably to standard heat treatment procedures.

Frequently Asked Questions (FAQ) about H13 / DIN 1.2344 Material
As a leading DIN 1.2344 material supplier, we frequently answer questions from engineers, manufacturers, and designers. Here are some of the most common ones.
Q1: What is the main difference between H13 and H13 ESR steel?
H13 ESR (Electro-Slag Remelted) is a higher-purity version of standard H13. The ESR process refines the molten steel, removing non-metallic inclusions and impurities. This results in a cleaner, more homogeneous steel with superior mechanical properties, particularly transverse toughness, fatigue resistance, and polishability. H13 ESR is recommended for the most demanding applications where tool failure is not an option.
Q2: Is DIN 1.2344 material the same as H13?
Yes, for all practical purposes, they are equivalent grades. H13 is the AISI designation (common in North America), while 1.2344 is the DIN designation (common in Europe). They have a virtually identical chemical composition and are manufactured to perform the same functions.
Q3: Can Milano Special Steel supply H13 material in custom sizes?
Absolutely. We specialize in providing custom-cut pieces according to your precise requirements. Whether you need a specific plate size or a cut-to-length round bar, our state-of-the-art cutting facilities can deliver. This service helps you minimize material waste and machining time.
Q4: What is the typical hardness of H13 steel after heat treatment?
The final hardness of H13 depends on the tempering temperature. It typically ranges from 45 to 52 HRC (Rockwell Hardness C). A higher tempering temperature results in lower hardness but greater toughness, so the final hardness is chosen based on the specific application’s demands for wear resistance versus shock resistance.
Q5: Why is H13 a good choice for aluminum die casting?
H13 is the industry standard for aluminum die casting due to its exceptional resistance to thermal fatigue. The die is subjected to extreme temperature cycles—from molten aluminum at over 660°C to cooling sprays. H13’s ability to withstand this repeated expansion and contraction without cracking (heat checking) gives it a long and reliable service life.
Q6: Do you serve both large industrial clients and smaller workshops?
Yes. At Milano Special Steel, we cater to both wholesale and retail customers. Whether you need a large tonnage for a major production run or a single cut piece for a prototype, we provide the same level of dedicated service and competitive pricing.
