Yes — 45# steel is medium carbon steel — strong, moderately tough, and easy to machine. Perfect for shafts, gears, bolts, and other mechanical parts. But it can rust when exposed to air and moisture.

You can take simple precautions when ordering and handling:
✅ Oiling—Simply add a note when you order to help reduce the risk of rust during shipping or storage.
✅ Surface Blackening—Can be selected as a finishing option to form a protective layer against rust. Remember: if the blackened layer wears off, the steel underneath may still rust.

💡 Tip: For particularly humid or long-term outdoor use, regular maintenance or additional protective measures are recommended to prolong part life.
