Delves into the widespread problem of compositional misrepresentation and supplier "cosmetic marketing."
Composition Non-Conformance: Actual carbon content reaches 0.7%–0.9%, far exceeding the standard limit of ≤0.5%, increasing the risk of steel brittleness at low temperatures
Misleading Presentations: Modern facilities shown online are often rented outdated plants with non-functional environmental systems
Middleman Risks: Multi-layer distribution makes traceability and claims difficult; direct sourcing from original manufacturers is recommended
Testing Recommendations: On-site sampling combined with portable spectrometer rapid testing, supplemented by blind sample inspections for dual verification
