Surface-treated Carbon Steel Castings

  • Net-shape casting: Near-final geometry reduces or eliminates secondary machining, saving time and tooling cost.
  • High strength & toughness: Carbon steel grades provide robust mechanical performance for heavily loaded or impact tools.
  • Rich surface treatments: Hot-dip galvanizing, zinc and chrome plating, painting, powder coating, polishing, anodizing, black oxide, and more.
  • Fine surface finish: Casting roughness as low as Ra1.6–3.2 with tight machining tolerance up to ±0.009 mm.
  • Flexible production capacity: 100–150 tons per month with stable 45-day lead time for regular orders.
