In the world of high-performance tooling materials, tool steels play a vital role in meeting demanding mechanical, thermal, and wear-resistance requirements. Among them, 1.2767 tool steel stands out as a premium-grade alloy used in heavy-duty applications. Known for its high hardness, excellent toughness, and good hardenability, 1.2767 is widely used in plastic molds, shear blades, and industrial tools.
One common question among engineers, purchasers, and manufacturers is:
What is the equivalent of 1.2767 tool steel in other international standards?
This article will explore the equivalents of 1.2767, its chemical and mechanical properties, applications, and how global buyers can confidently source this material.
1.2767 is a high-alloy tool steel under the DIN (German) standard, known for its high nickel content and exceptional toughness even at high hardness levels. It belongs to the cold work tool steel group and is suitable for parts requiring high mechanical strength and resistance to impact.
High toughness and ductility
Good wear resistance
Excellent hardenability
Suitable for polishing
Can be nitrided or coated
Good machinability in annealed condition
Here is the typical chemical composition of 1.2767:
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.45 – 0.55 |
| Chromium (Cr) | 1.30 – 1.70 |
| Manganese (Mn) | 0.20 – 0.40 |
| Molybdenum (Mo) | 0.15 – 0.35 |
| Nickel (Ni) | 3.80 – 4.30 |
| Silicon (Si) | 0.10 – 0.40 |
The high nickel content is key to its excellent toughness and impact resistance, even in hardened conditions.
To ensure global compatibility, the equivalent grades of 1.2767 across different standards include:
| Standard | Equivalent Grade |
|---|---|
| AISI / SAE | L6 |
| ASTM | A681 L6 |
| JIS (Japan) | SKT4 |
| BS (UK) | BD2 |
| AFNOR (France) | 55NiCrMoV7 |
| ISO | 55NiCrMoV7 |
Among all equivalents, AISI L6 is the most widely accepted match for 1.2767 tool steel. It is classified as a tough, oil-hardening tool steel in the AISI system and is known for similar mechanical behavior.
| Property | Value |
|---|---|
| Hardness (after heat treatment) | 55 – 60 HRC |
| Tensile Strength | Up to 2000 MPa |
| Impact Resistance | Excellent |
| Hardenability | Excellent (air or oil) |
| Working Temperature | Up to 500°C in some applications |
These properties make 1.2767 and its equivalents highly desirable in applications where shock, pressure, and wear resistance are critical.
Due to its high toughness and strength, 1.2767 and its equivalents are used in a wide variety of tooling and industrial applications:
Plastic injection molds (especially for reinforced plastics)
Punches and dies for cold working
Shear blades and cutters
Industrial knives
Extrusion dies
Forging dies for light alloys
Die-casting tools
Tools for deep drawing and forming
In the mold and die industry, 1.2767 is often chosen for tools that are exposed to cyclic loading and high mechanical stress.
Here are the top advantages of choosing 1.2767 or equivalent materials like L6:
It can be heat-treated to achieve high hardness without becoming brittle. This makes it ideal for tools that undergo repeated impact.
Thanks to its good hardenability, large cross-section tools can be uniformly hardened.
The steel shows excellent dimensional stability during quenching and tempering.
It can be polished to a high finish, suitable for mirror-finish molds.
With equivalents like L6 and SKT4, buyers can source similar grades from multiple countries and suppliers like sakysteel.
Proper heat treatment is crucial for achieving the desired properties. Typical steps include:
Annealing:
650 – 700°C, slow furnace cooling
Soft annealed to around 220 HB
Hardening:
Preheat to 600 – 650°C
Austenitize at 850 – 870°C
Quench in oil or air
Tempering:
200 – 600°C depending on application
Typically tempered twice to relieve stress
In the annealed condition, 1.2767 has good machinability, though not as high as some lower alloy steels. Carbide tools and proper coolant systems are recommended. Surface treatments such as nitriding, PVD coating, or plasma nitriding can enhance wear resistance and service life.
Whether you need 1.2767 or its equivalents like AISI L6, quality and traceability are critical. Always choose reputable suppliers with consistent quality control and documentation.
