45# High Quality Carbon Steel Billet – Machinery Forging Grade
Product Overview
45# high quality carbon steel billet is a medium carbon mechanical grade feedstock designed for machinery component manufacturing. With controlled carbon content and good hardenability, it delivers excellent machinability, moderate strength and reliable heat treatment response. This machinery grade is the standard material for shafts, gears, forgings and general mechanical parts requiring balanced strength and machinability.
Why Choose CNB Quality Carbon Billets?
Our 45# steel billets are sourced from specialized quality carbon steel mills with strict control over carbon content and internal quality. Every billet undergoes chemical analysis and hardness verification to ensure consistent machining and heat treatment performance. We offer both cast and forged billets in various sections and sizes to match different machining and forging requirements.
