Cold-Rolled Grain-Oriented (CRGO) Electrical Steel

Prelims – General economics

Why in news?

Recently, the Directorate General of Trade Remedies (DGTR), has initiated an anti-dumping probe against imports of CRGO.

CRGO steel – It is a special type of high-tech iron and steel blend made specifically to build the inside (the "core") of electrical transformers.

Functions

One-Way Path - The metal crystals are lined up in a single direction.
Easy Flow - This alignment lets electricity and magnetism flow smoothly with very little resistance.

Features

Saves Energy - It stops power from leaking or turning into wasted heat.
Lowers Bills - It keeps our power grid highly efficient, saving money and energy.
Prevents Overheating - It keeps giant transformers cool and safe while they step voltage up or down. Produces less heat and higher efficiency resulting into low core loss
High Magnetic Permeability – Enables easy flux conduction.
Thickness Range – 0.23–0.35 mm (modern grades as thin as 0.18 mm).
Reliance on Imports – India consumes 400,000–450,000 tonnes of CRGO steel annually, but domestic output is only 40,000–50,000 tonnes.
Imports from China, Japan, South Korea, and Russia meet about 90% of demand.

“Anti-dumping duties are tariffs designed to shield domestic industries from foreign products priced below fair market value.”

Risks of Anti-Dumping Duty

Imposing duties may increase transformer prices.

Slower Expansion – Higher costs could delay investments in transmission infrastructure, renewable integration, and electricity distribution.
Limited Impact on Imports – Since domestic production meets less than one-tenth of demand, duties are unlikely to significantly reduce import dependence.

Implications for India

In the power sector, increasing transformer costs may adversely affect grid expansion timelines.
The integration of solar and wind projects may experience delays as a result of higher equipment costs.
Manufacturers may encounter challenges due to increased input costs, which could negatively impact their competitiveness.
