C45 vs EN8 Steel Plate Comparison
A reliable C45 Carbon Steel Plates Supplier in India ensures fast nationwide delivery.
EN8 (080M40) Steel Plate
- Carbon capped near 0.40%
- Lower core hardness after treatment
- Easier to machine and weld
- Used for lightly loaded shafts
C45 Carbon Steel Plates
- Carbon held at 0.42 – 0.50%
- Higher wear resistance after hardening
- Better strength-to-cost ratio
- Preferred for gears and heavy shafts
C45 Plate Heat Treatment & Hardness Levels
From Cast Billet To Treated Plate
How EN 10083 C45 Steel Plate is treated to reach the hardness a buyer needs.

C45 Carbon Steel Plates Frequently Asked Questions
What is C45 carbon steel sheets?
C45 is a medium carbon, non-alloy steel under EN 10083-2. It suits gears, shafts and machine parts.
What is the cost of C45 steel plate?
Price tracks the daily billet rate, thickness and finish. Send your size list for a same-day quote.
Is C45 material equivalent to EN8?
Not exactly. C45 carries more carbon than EN8, so it hardens harder and wears better.
What is the difference between C45 and C45E?
C45E is the fine-grain, tighter-chemistry version. Both share the same carbon band.
What is the HSN code for C45 Carbon Steel Plates?
HSN 7208, taxed at 18% GST in India.
