I. Differences in Composition and Properties

Though both belong to electrical steel, ဆီလီကွန်သံမဏိ and hydroelectric steel feature stark core distinctions:

• Silicon steel: Silicon content ranges from 3% to 5%. It delivers high magnetic permeability and low core loss, suitable for environments with high-frequency alternating magnetic fields.
• Hydroelectric steel: Alloyed with aluminum, chromium and other elements, it boasts outstanding corrosion resistance and excellent resistance to water flow impact.

Physical traits: Silicon steel is thinner (0.2–0.35 mm), while hydroelectric steel generally comes in thicknesses of 1–3 mm.

II. Segmented Application Scenarios

Their unique properties define their exclusive application fields:

• Primary uses of silicon steel: Electromagnetic conversion equipment such as transformer cores, motor stators and rotors.
• Primary uses of hydroelectric steel: Water-exposed components including hydro-generator rotors and hydraulic turbine blades.

Cross-field exception: Some hydropower projects adopt silicon steel for iron cores and hydroelectric steel for protective structural parts.

III. Key Points for Material Selection

Material selection is similar to matching components, determined by core requirements:

• Prioritize silicon steel if high electromagnetic efficiency is demanded.
• Choose hydroelectric steel for working conditions with high humidity and corrosion risks.
• Cost comparison: Silicon steel involves more complex processing, yet hydroelectric steel carries higher alloy raw material costs.
• Service life cycle: Hydroelectric steel shows remarkable durability advantages in humid service environments.
