H13 Steel Supplier in India | High-Quality Hot Work Tool Steel
Introduction to H13 Steel
H13 steel is a premium hot work tool steel renowned for its outstanding combination of hot strength, toughness, and resistance to thermal fatigue. This grade is specifically engineered to perform reliably at elevated temperatures, making it a top choice for hot forging, die casting, and extrusion tooling. Its superior properties allow it to withstand repeated heating and cooling cycles without significant deformation or cracking. At Jupiter Steels, based in Delhi, we are a trusted stockist and supplier of H13 steel, providing certified material to businesses throughout India, including industrial hubs in Manesar, Haryana, and beyond.
Chemical Composition of H13 Steel
The outstanding performance of H13 tool steel is a direct result of its carefully balanced chemistry. The key alloying elements and their typical weight percentages are:
- Carbon (C): 0.32 – 0.45%
- Chromium (Cr): 4.75 – 5.50%
- Molybdenum (Mo): 1.10 – 1.75%
- Vanadium (V): 0.80 – 1.20%
- Silicon (Si): 0.80 – 1.20%
Functioning and Reasoning of Chemical Elements
- Chromium (Cr) & Molybdenum (Mo): This combination is the core of H13 steel. Chromium provides high-temperature strength and wear resistance. Molybdenum enhances its hot hardness and prevents temper brittleness.
- Vanadium (V): Vanadium forms extremely stable carbides that significantly increase the steel’s resistance to wear and abrasion at elevated temperatures.
- Silicon (Si): Silicon improves the steel’s oxidation resistance and contributes to its hot strength.
Hardness, Properties, and Applications of H13
Hardness
After heat treatment, H13 steel can achieve a wide range of working hardness, typically in the range of 40-55 HRC, depending on the specific application and tempering temperature.
Properties
- Exceptional Hot Strength: It maintains a high level of hardness and strength even at elevated temperatures, which is critical for hot work tooling.
- Resistance to Thermal Fatigue: It withstands the repeated heating and cooling cycles common in hot work applications without cracking or crazing.
- Good Toughness: It provides sufficient toughness to resist impact and mechanical shock, a key requirement for dies and punches.
- Good Machinability: In its annealed condition, it can be easily machined into complex shapes before the final heat treatment.
Applications
H13 hot work tool steel is extensively used for tooling that operates under high temperature and pressure. Key applications include:
- Die Casting Dies for aluminum, magnesium, and zinc alloys
- Hot Forging Dies
- Extrusion Tooling for both metal and plastic
- Punches and Cores for hot work applications
- Mandrels and Tool Holders

H13 Steel FAQ Section
Q1: What is H13 steel used for?
: H13 steel is primarily used for hot work tooling, such as die casting dies, hot forging dies, and extrusion tooling that operate at high temperatures.
Q2: What is the main benefit of using H13 steel?
: The main benefit is its exceptional hot strength and its resistance to thermal fatigue and cracking under repeated heating and cooling cycles.
Q3: Is H13 suitable for cold work applications?
: While it can be used for some cold work applications, H13 is specifically designed for hot work. Other tool steels are often better suited and more cost-effective for pure cold work.
