EN8 Material Hardness in HRC – Precision Induction Hardening Services

Surface Hardness up to 55 HRC | 1–3 mm Case Depth | Controlled Core Softness

At Thakur Industries, we specialize in induction hardening of EN8 steel, delivering consistent surface hardness ranging from 48–52 HRC (practical) and up to 55 HRC (max achievable). Our advanced setup ensures controlled case depth of 1–3 mm while maintaining a core hardness of ~20–30 HRC for shock absorption.

Serving Ludhiana, Punjab, and PAN India, we are trusted by OEMs, machine part manufacturers, and fabrication shops for high-precision heat treatment of EN8 shafts, gears, rollers, and pins.

Our Induction Hardening Process for EN8

We use Boss Engineers high-frequency induction machines to provide targeted surface hardening with minimal distortion and repeatable HRC results.

How It Works:

Material Verification – Check carbon content and heat treatability

Induction Heating – Raise surface temp to ~850–900°C

Controlled Quenching – Spray quenching to lock martensite structure

Tempering (if required) – Stress relieving & hardness tuning

Final HRC Testing – Surface & case depth confirmation

🏭 Ideal for EN8 Shafts, Gears, Pins & Rollers

EN8 is widely used in automotive, general engineering, and agricultural sectors. Our hardening treatment makes it suitable for:

Transmission shafts
Gear hubs and sprockets
Axles and connecting rods
Timing pulleys
Textile rollers
Tooling components

📌 Our treatment balances high wear resistance (surface) with shock resilience (core)—perfect for rotating, sliding, and load-bearing parts.
