C45E4 application fields
C45E4 carbon steel has moderate strength and hardness and is suitable for general engineering applications. C45E4 is easy to machine, has good cutting performance, and is suitable for manufacturing various parts and tools. C45E4 has good toughness and can resist stresses such as impact and extrusion to a certain extent.
Due to its moderate carbon content, C45E4 is wear-resistant to a certain extent and is suitable for applications where resistance to friction and wear is required.
use:
Manufacturing mechanical parts: C45E4 is used to manufacture mechanical parts, such as bearings, pins, gears, connecting rods, etc.
Making cutting tools and blades: Due to its good machinability, C45E4 is suitable for manufacturing various cutting tools, such as blades, drill bits and tool blades.
Making molds: C45E4 can be used to make some molds, such as stamping molds, plastic injection molds, etc.
Parts processing: C45E4 is suitable for machining various parts, such as bolts, nuts, pins, etc.
Forgings: C45E4 is suitable for manufacturing forgings of various shapes, and its properties can be adjusted through appropriate heat treatment to achieve the required hardness and strength.
C45E4 heat treatment methods include annealing, normalizing and quenching.
1. Annealing: Heat C45E4 to a temperature range of approximately 800°C-900°C, maintain it for a certain period of time and then slowly cool down. Annealing can relieve stress and improve the toughness and processability of steel. The annealing process generally includes full annealing and spheroidizing annealing.
2. Normalizing: Heat C45E4 to a temperature range of approximately 830°C-900°C, maintain it for a certain period of time and then cool it with air cooling. Normalizing can improve the hardness and strength of steel, but it has better toughness than quenching.
3. Quenching: Heat C45E4 to the appropriate temperature (usually 830°C-900°C), and then quickly cool it to room temperature or low-temperature medium, such as water, oil or brine. Quenching can quickly form a martensite structure in steel, thereby improving its hardness and strength. However, quenching makes the steel brittle, at which point tempering is often required to improve its toughness and impact resistance.
4. Tempering: Reheat the quenched C45E4 to a temperature range of about 150°C-500°C, keep it for a certain period of time and then cool it. Tempering can reduce the internal stress formed during the quenching process, improve the toughness and ductility of the steel, and is suitable for some applications that require both hardness and toughness.
