Maintenance Tips For EN Series CS Round Bars
Simple yard and pre-machining practices that protect your bar stock from corrosion and dimensional drift
Store Off The Ground
Keep bar on racks or dunnage, not directly on concrete or soil
Tip 1
Keep Oil Film On Bright Bar
A light rust-preventive film limits surface staining before machining
Tip 2
Segregate By Heat Number
Avoid mixing heats or grades to keep MTC traceability intact
Tip 3
Anneal Before Deep Machining
Soften stock if it has hardened in transit before heavy cuts
Tip 4
Re-check Straightness
Long bar can bow in transit – verify before precision turning
Tip 5
Surface Finish Options For Carbon Structural Steel EN Series Bar
Black / Hot Rolled
- Mill-scale surface
- Lowest cost option
- Suited to further machining
Bright / Peeled
- Centreless peeled surface
- Close h9 tolerance
- Reduced machining stock
Ground & Polished
- Fine surface finish
- Precision shaft-ready
