4140 Steel Pipe, 1.7225, 42crmo4 alloy Steel
The 4140 steel pipe, also identified as 1.7225 or 42CrMo4, is a seamless chrome-molybdenum alloy steel tube engineered for high-stress mechanical and structural applications. It conforms to standards such as ASTM A29 and EN 10297-1, delivering tensile strength and fatigue resistance critical for demanding environments. The alloy’s chromium and molybdenum content enhances its hardenability, toughness, and resistance to wear, making it a preferred choice for automotive, machinery, and oilfield equipment.
This seamless pipe is produced to precise dimensional tolerances, with typical outer diameters ranging from 20 mm to 300 mm and wall thicknesses from 2 mm to 50 mm. The material is often supplied in the annealed or normalized condition, though it can be heat-treated to achieve specific mechanical properties. Standard surface finishes include black, peeled, or cold-drawn, depending on the application’s requirements. The pipe’s versatility allows it to be used in both high and low-temperature service conditions.
Industrial buyers source 4140 steel pipe for applications requiring high strength-to-weight ratios, such as drive shafts, hydraulic cylinders, and structural frameworks. The material’s ability to withstand dynamic loads and cyclic stresses makes it ideal for heavy machinery and construction projects. For bulk orders, specify the required diameter, wall thickness, and length to ensure compatibility with your engineering specifications. Confirm the supplier’s ability to provide material test reports and third-party certifications for critical applications.

Sourcing 4140 Steel Pipe, 1.7225, 42CrMo4 Alloy Steel from Dongguan Otai Special Steel Co Ltd - China Import Guide
Prior to ordering, confirm the supplier’s ability to meet your exact dimensional requirements, including outer diameter, wall thickness, and length. Request samples or a first-article inspection report to verify the pipe’s compliance with your engineering drawings. Ensure the material test report (MTR) is provided to confirm the alloy’s chemical composition and mechanical properties.
Discuss logistics details such as packaging, loading port, and Incoterms to avoid delays during shipment. For seamless pipes, clarify whether the material will be supplied in straight lengths or coils, and confirm the packaging meets export standards to prevent damage. Lead times may vary based on customization, so agree on a delivery schedule that aligns with your project timeline.
Quality checks should include dimensional verification, hardness testing, and non-destructive testing (NDT) for critical applications. For oilfield or automotive use, request additional certifications such as ISO or API to ensure compliance with industry standards. Documentation such as the MTR, heat treatment records, and compliance certificates should accompany the shipment for full traceability.
