Carbonitrided SAE1045/C45 Forged Steel Discs - Precision Round Blanks for Drilling Machinery

SAE1045/C45 medium-carbon steel forged disc with a carbonitrided surface layer (case depth 0.2–0.5 mm), achieving a surface hardness of HV700–850 and offering both wear and fatigue resistance. The forging’s grain structure is refined through multi-directional forging. Suitable for gears, bearing housings, and other components in drilling machinery, capable of withstanding impact loads and friction during drilling operations.

Applicable Heat Treatment	Normalization, annealing, quenching and tempering, Case Hardening, Nitriding, Carbon Nitriding, Induction Quenching
Applicable Finish Surface Treatment	Shot/sand blast, polishing, Surface passivation, Primer Painting , Powder coating, ED- Coating, Chromate Plating, zinc-plate, Dacromat coating, Finish Painting,
Lead Time	About 20-120days from the receipt date of deposit for casting stainless steel

What Is Forged Steel? Forged steel is steel that has been shaped by applying compressive force — hammer blows, press tonnage, or die pressure — while the metal is at an elevated temperature, typically between 1,100°C and 1,250°C (2,000°F–2,300°F) for hot forging. The mechanical working breaks up ca...
