HR, CR & CARBON STEEL

Mild Steel

Mild steel is a versatile, low-cost, ductile, and easily machinable steel, widely used in construction, automotive, fabrication, and general engineering. Its uniform properties, affordability, and ease of welding make it the most popular steel worldwide.

Benefits of Mild Steel

General Benefits of Mild Steel
  • Cost-Effective : One of the most affordable metals for construction and manufacturing.
  • High Strength & Toughness : Good load-bearing capacity with impact resistance.
  • Excellent Weldability : Easy to weld, cut, bend, and fabricate.
  • Versatile Applications : Widely used in structural, automotive, machinery, and consumer goods.
  • Recyclable : Eco-friendly and sustainable with 100% recyclability.
  • Availability : Easily available in multiple forms (plates, sheets, coils, sections).
Benefits of Hot Rolled (HR) Mild Steel
  • Cost Advantage : Cheaper than CR due to simpler processing.
  • High Workability : Softer and easier to form, bend, and cut.
  • Good for Structural Use : Common in beams, channels, angles, and construction.
  • Large Size Availability : Available in bigger thicknesses and dimensions.
  • Resistant to Warping : Suitable for welding and fabrication in heavy industries.
Benefits of Cold Rolled (CR) Mild Steel
  • Superior Surface Finish : Smooth, clean surface ideal for precision components.
  • Tighter Tolerances : Better dimensional accuracy and uniform thickness.
  • Increased Strength : Higher tensile strength due to work hardening.
  • Aesthetic Advantage : Preferred in applications where appearance matters.
  • Versatility : Common in automotive panels, furniture, appliances, and precision engineering.
Benefits of Carbon Steel (Medium & High Carbon)
  • Higher Strength & Hardness : More durable compared to low-carbon steel.
  • Wear Resistance : Ideal for tools, dies, and heavy-duty parts.
  • Heat Treatment Friendly : Can be hardened, tempered, and annealed for custom properties.
  • Structural Reliability : Widely used in automotive parts, shafts, rails, and cutting tools.
  • Longevity : Longer life in applications requiring strength and durability.
Comparative Table

Hot Rolled vs Cold Rolled vs Carbon Steel

Property / Feature Hot Rolled (HR) Mild Steel Cold Rolled (CR) Mild Steel Carbon Steel (Medium & High Carbon)
Process Rolled at high temperature (~1000°C) Rolled at room temperature after HR process Higher % Carbon content (0.3–1.5%), heat treated for strength
Surface Finish Rough, scaled, less precise Smooth, clean, superior finish Can be finished (ground, polished, coated)
Dimensional Accuracy Moderate (looser tolerances) High precision & tighter tolerances Varies depending on treatment & grade
Strength Moderate strength & toughness Higher strength due to strain hardening Very high strength & hardness
Formability / Workability Excellent for bending, welding, fabrication Good, but less ductile than HR Limited ductility (harder to bend/form)
Cost Lower (economical) Higher (due to extra processing) Higher than mild steel (depends on grade)
Applications Structural beams, channels, plates, heavy construction, pipes Automotive panels, appliances, furniture, precision engineering Cutting tools, dies, shafts, rails, gears, heavy-duty machinery
Thickness Range Available in thicker sizes Available in thinner, precision sheets Varies – depends on grade & application
Aesthetic Value Not appearance-focused Preferred where look matters Not for aesthetics, mainly for performance
Recyclability 100% recyclable 100% recyclable 100% recyclable
