HCHCR-D2 STEEL
1.2379 / D2 for hardness, wear resistance and dimensional stability.
One of the most common cold-work tool steels across the world is known as D2 tool steel which has high levels of hardness, wear resistance and dimensional stability. D2 is a high-carbon, high-chromium tool steel, in which severe abrasion, heavy friction and high-pressure cutting conditions are resisted. At Manjula Steel Industries, we are distributors of fine 1.2379 / D2 tool steel that is best suited in production of blanking die, punches, shear blades, industrial cutters, forming tools, and most other precision parts employed in cold-works.
The 1.2379 / D2 tool steel has a perfect balance of toughness and strength, thus making it a better choice in the industries that require long-term wear-resistant and tough tooling solutions. D2 tool steel has semi-stainless steel characteristics, as it contains high levels of chromium, approximately 12% and, therefore, it has a better corrosion resistance than other cold-work steels. The fact that it may be used without disregarding hardness even after a long usage cycle makes it one of the most reliable options available to tool manufacturers that need to rely on the same performance even during prolonged production cycles.
At Manjula Steel Industries, we know the importance of having stability of the material and performance at tool steel usage. That is why we present to you top-quality, properly sized, and industry tried 1.2379 / D2 tool steel which can be used even in the most arduous tasks.
Strong performance for demanding cold-work tooling.
1.2379 / D2 tool steel has become popular in the world because of its strong abrasion resistance, compressive strength, and edge retention. It is so hard, up to 62 HRC with appropriate heat treatment that it is widely used in situations where there is a lot of contact with any metal, sheet or abrasive surfaces.
Since D2 is an air-hardening steel, there is minimum distortion during the heat-hardening process and thus the components are dimensionally stable even after hardening. The great amount of chromium helps to provide a protective layer against corrosion and the wear and galling resistance of the steel. This renders 1.2379 / D2 extremely viable when it comes to long-lasting tools and applications when there is a need to have stable tolerances.
At Manjula Steel Industries, we supply 1.2379 / D2 tool steel that meets strict international metallurgical standards. Our material is thoroughly tested for purity, hardness, uniformity, and structural consistency, ensuring long-term, high-performance results for our clients.
