Special steel offers a variety of case hardening grades, each with its own distinct properties and uses. Some of the commonly employed grades are:
1. 8620: This grade is commonly utilized for high-stress applications like gears and shafts. Its remarkable toughness and resistance to wear make it ideal for parts requiring both durability and strength.
2. 9310: Aerospace applications often rely on this grade due to its high strength and resistance to fatigue. It is frequently employed for gears, bearings, and components demanding exceptional toughness and load-carrying capacity.
3. 4340: Known for its hardenability and high strength, this grade is suitable for parts necessitating great tensile strength and impact resistance, such as crankshafts, connecting rods, and gears.
4. 20MnCr5: This grade finds frequent use in the production of gears, camshafts, and components requiring high surface hardness and resistance to wear. It boasts excellent case-hardening properties and good core strength.
5. EN36C (also referred to as 655M13): This grade is commonly employed for axles, shafts, and crankshafts requiring high tensile strength. Its good hardenability and exceptional toughness make it suitable for heavy-duty applications.
To ensure the right grade is chosen for a specific project, it is crucial to consider the application requirements, including desired hardness, strength, and wear resistance. Seeking advice from a metallurgist or materials science expert can aid in selecting the appropriate case hardening grade.
There are several different case hardening grades of special steel, each with its own unique properties and applications. Some of the most commonly used case hardening grades include:
1. 8620: This grade of steel is commonly used for gears, shafts, and other high-stress applications. It has excellent toughness and wear resistance, making it ideal for parts that require both strength and durability.
2. 9310: This grade is often used for aerospace applications due to its high strength and resistance to fatigue. It is commonly used for gears, bearings, and other components that require exceptional toughness and load-carrying capacity.
3. 4340: This grade is known for its high strength and hardenability. It is commonly used for parts that require high tensile strength and good impact resistance, such as crankshafts, connecting rods, and gears.
4. 20MnCr5: This grade is often used in the manufacturing of gears, camshafts, and other components that require high surface hardness and wear resistance. It is known for its excellent case-hardening properties and good core strength.
5. EN36C: Also known as 655M13, this grade is frequently used for making components that require high tensile strength, such as axles, shafts, and crankshafts. It has good hardenability and excellent toughness, making it suitable for heavy-duty applications.
It is important to select the appropriate case hardening grade based on the specific application requirements, such as desired hardness, strength, and wear resistance. Consulting with a metallurgist or an expert in materials science can help ensure the right grade is chosen for a particular project.
There are several different case hardening grades of special steel, including but not limited to, 1018, 1020, 8620, and 9310. These grades are specifically formulated to provide increased strength and wear resistance by creating a hardened outer layer, or case, while maintaining a softer, more ductile core.
