DIN 1.2379 | X155CrVMo12-1 Tool Steel | Supplier & Stockist in UAE – Nifty Alloys LLC
 

When your operations demand exceptional wear resistance, high compressive strength, and reliable dimensional stability, selecting the right tool steel is critical. For demanding cold work applications, X155CrVMo12-1 (also known as Werkstoff Nr. 1.2379) stands as a premier choice. This high-carbon, high-chromium tool steel is engineered to deliver superior performance where other materials fall short.

At Nifty Alloys, we understand that the integrity of your components begins with the quality of your materials. This comprehensive guide provides the technical information you need to confidently specify X155CrVMo12-1 for your projects. We will cover its chemical composition, mechanical and physical properties, heat treatment processes, and key industrial applications, ensuring you have the data required for successful design and procurement.

What is X155CrVMo12-1 Tool Steel?

X155CrVMo12-1 is a ledeburitic, 12% chromium cold work tool steel known for its excellent toughness and wear resistance. It belongs to the D2 tool steel group under the AISI classification system, though it has distinct compositional nuances that enhance its performance characteristics. The high concentration of chromium and carbon forms hard, wear-resistant carbides within the steel's matrix, making it exceptionally durable for high-stress tooling applications.

The addition of molybdenum and vanadium further refines the steel's properties. Molybdenum improves hardenability and strength at elevated temperatures, while vanadium helps form very hard carbides that significantly increase wear resistance. This balanced chemical composition results in a material that offers a superior combination of hardness, toughness, and dimensional stability after heat treatment.

For procurement managers and engineers in the UAE and surrounding regions, sourcing certified X155CrVMo12-1 ensures that your tools and dies meet rigorous performance standards. Every batch we supply is backed by mill test certificates (MTRs), confirming its compliance with international standards and providing you with complete material traceability.

Key Characteristics of X155CrVMo12-1
 

When you specify X155CrVMo12-1 for your projects, you are selecting a material defined by its performance attributes:

• Exceptional Wear Resistance: The high volume of hard carbides in its microstructure, primarily from chromium and carbon, delivers superior resistance to abrasive and adhesive wear. This extends the service life of tools and components, reducing downtime and replacement costs.
• High Compressive Strength: This steel can withstand significant compressive forces without deforming, making it ideal for stamping, forming, and cold extrusion applications.
• Good Hardenability: It achieves high hardness levels through air hardening, which minimizes distortion and cracking compared to liquid-quenching steels. This ensures predictable and stable dimensions after heat treatment.
• Decent Toughness: While its primary strength is wear resistance, X155CrVMo12-1 offers adequate toughness for many cold-work applications, providing a good balance of properties for tooling that requires resistance to both wear and chipping.

Advantages of Using X155CrVMo12-1

Choosing X155CrVMo12-1 for your tooling needs offers several distinct advantages that translate into tangible operational and financial benefits.

1. Extended Tool Life: The primary benefit is a significant increase in the service life of your tools and dies. The superior wear resistance means less frequent replacement, reduced maintenance downtime, and lower overall tooling costs.
2. Improved Product Quality: The high hardness and dimensional stability ensure that tools maintain their shape and cutting-edge sharpness. This results in greater consistency and precision in your manufactured parts, reducing scrap rates and improving final product quality.
3. High-Performance in Demanding Operations: This steel is not for standard applications; it is engineered for severe conditions. It allows you to process harder, thicker, and more abrasive materials that would cause other tool steels to fail prematurely.
4. Reliable and Predictable Performance: With its excellent dimensional stability during heat treatment and consistent properties, you can design and manufacture complex tools with confidence, knowing they will meet tight tolerances.
5. Versatility: While it is a cold work tool steel, its properties make it suitable for a wide range of cutting, forming, and wear-part applications, making it a versatile material to have in your inventory.

As a leading tool steel supplier in the UAE, Nifty Alloys ensures that the X155CrVMo12-1 you receive is of the highest quality, sourced from reputable mills and fully certified to meet your project specifications.
