CRC&HRC

What is the difference between HRC and CRC?


FeatureHRC (Hot Rolled Coil)CRC (Cold Rolled Coil)
Manufacturing ProcessRolled at high temperatures (above 1000°C)Further processed at room temperature after hot rolling
Surface FinishRough, scaled surface due to oxidationSmooth, polished surface with better aesthetics
Strength & HardnessSofter, more ductileHigher strength and hardness due to strain hardening
Dimensional AccuracyLess precise, subject to shrinkageHigher precision with tighter tolerances
CostMore cost-effectiveMore expensive due to additional processing
ApplicationsUsed in construction, pipelines, and shipbuildingUsed 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.


What is CRC in steel?


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.


How to check HRC hardness?


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:

    1. Clean the steel surface to remove dirt or coatings.

    2. Place the steel sample on the tester's anvil.

    3. Apply a minor load (10kg) to set the indenter.

    4. Apply a major load (typically 150kg) for a fixed time.

    5. 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.
