Superior Hardness and Durability
The EN8D Induction Hardened Rod features a robust 50-55 HRC surface hardness achieved through a specialized induction hardening process, while a solid core maintains a hardness of 28-35 HRC. This combination ensures exceptional wear resistance, making it ideal for hydraulic cylinders, pneumatic rods, and shafts subjected to rigorous use in automotive and industrial machinery.
Exceptional Surface Finish
Every rod is finished with hard chrome plating and meticulous polishing to achieve a silver-grey, metallic finish. This process delivers a remarkably low surface roughness (0.2 Ra m), reducing friction and promoting smooth mechanical operation. The chrome layer provides enhanced corrosion resistance, extending the lifespan of components in challenging environments.
Reliable Strength and Customization
With tensile strength between 600-800 MPa (before hardening) and yield strength exceeding 350 MPa, EN8D rods can withstand considerable mechanical loads. They are available in a variety of diameters (8 mm to 100 mm) and customizable lengths up to 6000 mm, catering to diverse project needs for distributors, manufacturers, and end users in India.
FAQs of EN8D Induction Hardened Rod:
Q: How is the surface hardness of the EN8D Induction Hardened Rod achieved?
A: The surface hardness, ranging from 50-55 HRC, is attained through a precise induction hardening process followed by tempering. This treatment rapidly heats the rods surface, creating a tough outer layer while maintaining a ductile core.Q: What are the primary applications of this induction hardened rod?
A: EN8D Induction Hardened Rods are mainly used in hydraulic and pneumatic cylinder rods, automotive shafts, and industrial machinery components that require high wear resistance, straightness, and core toughness.Q: When should I consider using hard chrome plated EN8D rods?
A: Choose chrome plated EN8D rods when your application demands a combination of enhanced corrosion resistance, a polished and low-friction surface, along with superior surface hardness for extended component life.Q: Where can these rods be sourced or customized in India?
A: EN8D Induction Hardened Rods are available through distributors, importers, manufacturers, retailers, suppliers, traders, and wholesalers across India, often with options for custom diameters and lengths.Q: What is the benefit of the rods high straightness and surface finish tolerance?
A: A straightness tolerance of 0.2 mm per meter and surface roughness 0.2 Ra m ensure reliable performance in precision applications, minimizing vibration, wear, and friction in high-speed or high-load environments.Q: How is the machinability of these rods, and can they be processed further?
A: EN8D rods are designed with good machinability, making them suitable for machining, cutting, or further finishing to meet exact application requirements.Q: What are the steps in the manufacturing process of these rods?
A: Manufacturing involves forming the EN8D low-carbon steel into rods, followed by induction hardening and tempering, then chrome plating and polishing to deliver the final product with exacting mechanical and surface properties.Tell us about your requirement
