Precision Hardening and StrengthEN19 rods undergo an induction hardening process, resulting in a robust outer layer of 5560 HRC while the core retains a ductile 2832 HRC. This combination ensures exceptional surface durability for heavy-duty applications while preserving impact resistance and flexibility within the core. Every rod boasts a straightness of 0.20.5 mm/meter to ensure seamless operation in dynamic environments.
Optimized for Industry StandardsManufactured from alloy steel and conforming to IS and BS 970 standards, EN19 rods are suitable for a broad spectrum of industriesranging from automotive to construction. Their chemical composition balances hardness and machinability, while the enhanced chrome-plated or precision-ground finish significantly improves corrosion resistance and surface longevity.
FAQs of EN19 Induction Hardened Rod:
Q: What is the typical process for manufacturing EN19 induction hardened rods?
A: The process begins with alloy steel rods (EN19) that are cut to size and machined for precise straightness. The rods undergo induction hardening, where the surface is rapidly heated and quenched, resulting in surface hardness between 5560 HRC. After hardening, the rods are either coated with hard chrome plating or precision ground for improved finish and enhanced corrosion resistance.
Q: How are EN19 rods typically used across industries?
A: EN19 induction hardened rods are primarily utilized in hydraulic piston rods, construction equipment, automotive components, and various types of heavy machinery. Their combination of high surface hardness, core toughness, and corrosion-resistant finish makes them suitable for applications demanding both strength and longevity.
Q: What benefits does the induction hardening process provide to EN19 rods?
A: Induction hardening creates a hard, wear-resistant outer surface while maintaining a tough and ductile core, which ensures superior durability and high impact strength. This dual-property profile is ideal for components subjected to heavy stress, shocks, or abrasive conditions.
Q: When should one choose a chrome-plated finish for EN19 rods?
A: A chrome-plated finish is recommended when enhanced corrosion resistance and improved surface smoothness are required, such as in hydraulic cylinders or outdoor machinery exposed to moisture or abrasive elements. The plating prolongs service life by protecting the rod against oxidation and wear.
Q: Where can these EN19 induction hardened rods be sourced in India?
A: EN19 rods are widely available throughout India via distributors, manufacturers, importers, retailers, suppliers, traders, and wholesalers. They may be ordered in customizable sizes and lengths to suit specific project requirements.
Q: How does the machinability of EN19 rods change after hardening?
A: EN19 rods display good machinability in the annealed condition. However, after induction hardening, only the core remains relatively machinable, while the hardened outer surface is more challenging to machine. Final machining should be completed prior to hardening for best results.
Q: What are the dimensional tolerances and how customizable are these rods?
A: EN19 induction hardened rods are available in diameters typically ranging from 16mm to 100mm and lengths up to 6 meters. Straightness is tightly controlled at 0.20.5 mm/meter, and further customization in dimensions is possible to match specific application requirements.
