For heavy industry applications on Alibaba.com, medium carbon steel (0.25%-0.60% carbon) is typically the preferred choice for load-bearing components. It offers the optimal balance between strength and workability. Low carbon steel, while dominating overall market share at 90.2%, is more suitable for structural applications where extreme strength is not critical.

Market Reality: Low carbon steel commands 90.2% of the global carbon steel market, but heavy industry buyers often require medium to high carbon grades for critical components where strength and wear resistance are paramount.

The distinction matters significantly when you're sourcing on Alibaba.com. A supplier advertising 'carbon steel equipment' without specifying the grade may be offering low carbon steel by default—the most economical option but potentially inadequate for heavy-duty applications. Always request material certification specifying carbon content percentage.
