H13 ESR: The Ultimate Choice for Hot Work Tooling
If you are looking for a tool steel that can withstand high temperatures and pressures, look no further than H13 ESR. This electro-slag-remelted grade of steel is specially designed for applications such as aluminum pressure die casting and other hot work tooling.
In this blog post, we will discuss the benefits of H13 ESR, its properties, its equivalent grades, and why you should choose Virat Special Steels as your supplier.
Understanding the Properties of H13 Steel
H13 steel is a chromium-molybdenum-vanadium alloy that belongs to the group of hot work tool steels. It has excellent resistance to thermal fatigue, wear, and softening at elevated temperatures. It also has good toughness and ductility, making it suitable for complex and heavy-duty molds and dies.
One of the key features of H13 steel is its electro-slag-remelting (ESR) process, which improves its cleanliness, homogeneity, and microstructure. ESR eliminates non-metallic inclusions, gas porosity, and segregation in the steel, resulting in higher quality and performance.
Some of the physical and mechanical properties of H13 steel are:
- Density: 7.8 g/cm3
- Specific heat capacity: 0.46 J/g°C
- Thermal conductivity: 24.9 W/m°C
- Coefficient of thermal expansion: 11.5 x 10-6 /°C
- Tensile strength: 1900 MPa
- Yield strength: 1600 MPa
- Elongation: 8%
- Hardness: 52-56 HRC
The Chemical Composition of H13 Steel
The chemical composition of H13 steel is as follows:
- Chromium (Cr): 4.75-5.50%
- Molybdenum (Mo): 1.10-1.75%
- Vanadium (V): 0.80-1.20%
- Carbon (C): 0.32-0.45%
- Silicon (Si): 0.80-1.20%
- Manganese (Mn): 0.20-0.50%
- Phosphorus (P): max 0.03%
- Sulfur (S): max 0.03%
- Iron (Fe): balance
Chromium enhances the wear resistance and corrosion resistance of the steel, while molybdenum and vanadium increase its hot hardness and temper resistance. Carbon provides strength and hardness, while silicon and manganese improve its machinability and toughness.
H13 Steel: Equivalent Grades Across Standards
H13 steel is widely used in various industries and applications, and it has different names and designations in different standards. Some of the equivalent grades of H13 steel are:
- DIN 1.2344
- JIS SKD61
- GB 4Cr5MoSiV
- AISI H13
- BS BH13
- EN X40CrMoV5
These grades have similar chemical compositions and mechanical properties to H13 steel, but they may differ in some aspects such as heat treatment, surface treatment, or quality control.
