H13 tool steel, known as the workhorse of hot work applications, is a versatile chromium-molybdenum hot work steel that offers a unique combination of strength, heat resistance, and toughness. Whether you're in die casting, extrusion, or forging, H13 is likely already a part of your production system.
At Goel Steel Enterprises, we are proud to supply H13 steel in both machined round bars and flats, available in various sizes and delivered in annealed, UT-tested, and MTC-certified condition.
🧪 Chemical Composition of H13 Tool Steel
Element | Percentage (%) | Role |
|---|---|---|
Carbon (C) | 0.32 – 0.45 | Strength and wear resistance |
Chromium (Cr) | 4.75 – 5.50 | Heat resistance, hardness retention |
Molybdenum (Mo) | 1.10 – 1.75 | Reduces softening at high temperatures |
Vanadium (V) | 0.80 – 1.20 | Toughness and grain refinement |
Silicon (Si) | 0.80 – 1.20 | Improves strength and oxidation resistance |
Manganese (Mn) | 0.20 – 0.50 | Toughness and hardenability |
This combination gives H13 the ability to withstand thermal shocks, which is crucial in hot metal forming processes.
🏗️ Properties of H13 Steel
Property | Performance |
|---|---|
Hardness (Annealed) | ~200 BHN |
Hardness (Hardened) | Up to 54–56 HRC |
Toughness | Excellent (resists cracking under heat/cold cycles) |
Heat Resistance | Outstanding – withstands up to 600°C |
Wear Resistance | High |
Machinability | Moderate (improved in annealed condition) |
Dimensional Stability | Very good |
🔄 Processing & Heat Treatment of H13
Before H13 reaches its final working form, it undergoes several metallurgical treatments:
🔹 1. Annealing
Softens the material for improved machinability. At Goel Steel Enterprises, H13 is supplied annealed with hardness around 200 BHN, ready for machining.
🔹 2. Pre-machining
We offer peeled/turned rounds and flats, saving valuable time for toolmakers and machine shops.
🔹 3. Hardening
H13 is typically hardened by oil or air quenching at ~1020–1050°C, then tempered based on the required hardness.
🔹 4. Tempering
Multiple tempering cycles ensure maximum toughness and reduced brittleness especially important for die casting tools.
🧰 Applications of H13 Tool Steel
H13 is the industry standard for hot work tool applications where strength and heat resistance are crucial.
🏭 Common Applications:
Die casting dies (Aluminium, Zinc)
Extrusion dies
Forging dies and tools
Hot shear blades
Mould inserts for plastic injection
Mandrels and punches
Hot stamping tools
Because of its ability to resist thermal fatigue and wear, H13 is perfect for tools exposed to repeated heating and cooling cycles.
