Product Definition
High carbon railroad spikes are premium-grade fasteners manufactured from 0.60-0.95% carbon steel (AISI 1060-1095 series), offering superior mechanical properties compared to standard spikes. The high carbon content enables:
Enhanced hardness: 30-40 HRC (Rockwell C scale)
Improved wear resistance: 2-3× service life vs. mild steel spikes
Optimized microstructure: Quenched & tempered martensitic structure
