H13 Tool Steel – High Performance Hot Work Tool Steel

What is H13 Tool Steel?

H13 Tool Steel is one of the most widely used hot work tool steels across industries that require strength, durability, and resistance to thermal fatigue. Known for its excellent toughness and ability to withstand repeated heating and cooling cycles, H13 is the standard choice for die casting, forging dies, extrusion tooling, and hot shear blades.

At Nifty Alloys, we supply premium quality H13 Tool Steel round bars, plates, and custom blocks to meet the exact requirements of your projects. Whether you need raw materials for heavy-duty dies or precision-machined components, we deliver tested and certified H13 steel globally.

Key Properties & Features of H13 Steel

When you choose H13, you gain:

• High toughness – Performs under heavy loads without cracking.
   
• Thermal fatigue resistance – Handles repeated heating and cooling in hot work applications.
   
• Wear resistance – Resists surface wear, even in high-stress operations.
   
• Good machinability – Easier to cut and machine compared to many other tool steels.
   
• Air-hardening steel – Minimizes distortion during heat treatment.
   
• Versatility – Suitable for both hot work and certain plastic molding applications.
