I. Mechanical Properties of Non-Oriented Silicon Steel

Non-oriented ဆီလီကွန်သံမဏိ is an all-rounder among electrical steels. Its unique grain structure delivers distinctive mechanical performance. The material maintains stable properties under alternating magnetic fields while possessing sufficient mechanical strength to sustain motor operation. In practical production, its yield strength generally ranges from 280 MPa to 450 MPa, and tensile strength falls between 350 MPa and 550 MPa. This wider numerical range compared with grain-oriented ဆီလီကွန်သံမဏိ reflects its isotropic characteristic.

II. Key Factors Influencing Mechanical Strength

Similar to temperature and timing control in cake baking, multiple factors jointly regulate the strength of ဆီလီကွန်သံမဏိ:

• Silicon content threshold: Strength peaks at a silicon content of 2.5%–3.5%; excessively high silicon content will increase brittleness.
• Thickness effect: The tensile strength of 0.35 mm thin sheets is on average 15%–20% higher than that of 0.5 mm gauges.
• Annealing process: Products from continuous annealing lines feature smaller strength fluctuation than those produced by batch annealing.

III. Recommendations for Material Selection and Application

Avoid the following common misconceptions to improve the reliability of motor design:

1. Misconception 1: Blind pursuit of ultra-high strength, which may worsen core loss indicators.
2. Misconception 2: Ignoring work hardening during stamping; a strength margin of 5%–8% is recommended.
3. Misconception 3: Neglecting the impact of insulating coatings; certain coatings can reduce yield strength by 3%–5%.
