Although rarely noticed by the general public, silicon steel has become deeply integrated into nearly every aspect of modern life. It is truly an indispensable “unsung hero” of today’s electrified society.
1. The “Hidden Heart” of Household Appliances
Household appliances such as refrigerators, air conditioners, washing machines, and microwave ovens all contain electric motors at their core. These motors rely on non oriented electrical steel (NOES) as a key material.
With its excellent magnetic properties and low energy loss, silicon steel enables appliances to operate more efficiently, quietly, and durably. For example, a high efficiency refrigerator equipped with a compressor motor made from premium electrical steel can achieve over 10% energy savings compared to conventional motors, significantly reducing electricity costs over time.
2. A Key Enabler of Green Mobility
Electric vehicles (EVs) depend on high-performance non-oriented electrical steel for their drive motors, which directly impacts vehicle range, power output, and efficiency.
Today, one in every four EVs worldwide is equipped with ultra-thin electrical steel produced by Baosteel. This so-called “feather thin” silicon steel, with a thickness of just 0.1 mm, delivers exceptional performance and supports the rapid growth of sustainable transportation.
In addition, traction motors and transformers used in metro systems, high speed rail, and other rail transit applications also rely heavily on silicon steel, ensuring efficient and safe daily commuting.
3. The “Energy Guardian” of Power Supply Systems
Every unit of electricity used at home typically undergoes at least three voltage transformations from generation to end use, and each stage depends on transformers.
Transformer cores are made from grain oriented electrical steel (GOES), whose low core loss characteristics significantly reduce energy losses during transmission. Studies show that transformers using high-performance GOES can reduce transmission losses by more than 30%, effectively contributing to energy savings on a national scale.
4. The Material Foundation of High-Tech Living
From smartphone chargers and laptop power adapters to wireless charging modules in smartwatches, miniature high-frequency transformers rely on ultra-thin silicon steel.
Emerging technologies—including humanoid robots, drones, and low-altitude aircraft—also depend on 0.1 mm-class ultra-thin electrical steel to achieve lightweight, high efficiency motor designs.
From the moment we wake up in the morning to the time we turn off the lights at night, silicon steel quietly supports the operation of modern life. It is, without exaggeration, a true “industrial staple” of the electrified world.
