45# Seamless Precision Steel Pipe, Custom Non‑standard Processing, Timely Delivery

45# seamless steel pipe (AISI 1045 / CK45) is medium‑carbon carbon structural steel. Cold‑drawn precision tubes feature tight dimensional tolerance, uniform wall thickness and excellent machinability. Heat treatment like normalizing & quenching‑tempering is available. Widely used for mechanical parts, drive shafts, hydraulic cylinders and structural components.

✅ Custom Non‑standard Service: Custom OD, wall thickness & cut‑to‑length per your drawing or sample. Secondary processing including cutting, chamfering, beveling & honing is available for small‑batch special sizes. ✅ High Precision: Tight OD & ID tolerance, smooth surface and good straightness for mechanical assembly. ✅ Timely Delivery: Large stock for standard sizes. Fast production scheduling for non‑standard orders, priority support for urgent orders with reliable logistics. ✅ Quality Assurance: Material test report & certificate available. UT / ET inspection & mechanical property test are supported.
