| Feature | HRC (Hot Rolled Coil) | CRC (Cold Rolled Coil) |
|---|---|---|
| Manufacturing Process | Rolled at high temperatures (above 1000°C) | Further processed at room temperature after hot rolling |
| Surface Finish | Rough, scaled surface due to oxidation | Smooth, polished surface with better aesthetics |
| Strength & Hardness | Softer, more ductile | Higher strength and hardness due to strain hardening |
| Dimensional Accuracy | Less precise, subject to shrinkage | Higher precision with tighter tolerances |
| Cost | More cost-effective | More expensive due to additional processing |
| Applications | Used in construction, pipelines, and shipbuilding | Used in automotive, appliances, and precision components |
What is HRC steel used for?
Construction & Infrastructure – Beams, bridges, and structural frames.
Automotive Industry – Chassis, wheel rims, and support structures.
Pipelines & Tubing – Oil and gas pipelines, pressure vessels, and welded tubes.
Shipbuilding & Heavy Machinery – Hulls, cranes, and industrial equipment.
Railway Tracks & Equipment – Tracks, wheels, and railway structures.
CRC (Cold Rolled Coil) refers to steel that has been processed at room temperature after hot rolling. Key characteristics of CRC include:
Higher Strength & Hardness – Increased tensile strength due to cold working.
Better Surface Finish – Smooth, clean surface ideal for painting and coating.
Improved Dimensional Accuracy – Tighter tolerances for precision applications.
Common Applications:
Automotive Components – Body panels, doors, and structural reinforcements.
Home Appliances – Refrigerators, washing machines, and air conditioners.
Electronics & Metal Furniture – Cabinets, enclosures, and metal racks.
Manufacturing & Fabrication – Precision-formed steel parts and machinery.
HRC hardness (Rockwell Hardness Scale C) is commonly tested using the Rockwell Hardness Test, which involves:
Using a Rockwell Hardness Tester:
A steel or tungsten carbide indenter is pressed into the material under a fixed load.
The depth of penetration determines the hardness level.
Common HRC Testing Procedure:
Clean the steel surface to remove dirt or coatings.
Place the steel sample on the tester's anvil.
Apply a minor load (10kg) to set the indenter.
Apply a major load (typically 150kg) for a fixed time.
Measure the depth of indentation and convert it to an HRC value.
Alternative Methods:
Brinell Hardness Test (BHN) for softer steels.
Vickers Hardness Test (VHN) for thin materials.
Mohs Hardness Test for quick field assessments.
