AISI 4140 seamless tubing from Exipei Steel Limited is a low alloy chrome molybdenum steel product engineered for high-stress mechanical applications. The tubing leverages the grade’s balanced composition of chromium, molybdenum, and manganese to deliver excellent tensile and yield strength, even under elevated temperature conditions. It is supplied in various outer diameter (OD) and wall thickness combinations, catering to industries like oil and gas, automotive, and heavy machinery.
Compared to AISI 4130, AISI 4140 has a slightly higher carbon content, which enhances its strength and hardenability while maintaining good toughness. The seamless manufacturing process ensures uniform grain structure and eliminates potential weak points, making it ideal for components such as drill collars, hydraulic cylinders, and machinery parts. Standard industry tolerances for this grade include OD tolerances of ±0.5% and wall thickness tolerances of ±10%, though exact values should be confirmed with the supplier.
Exipei Steel Limited positions this tubing for global trade, with active demand across Asia, Europe, and North America. The product’s versatility extends to applications in drilling equipment, structural frameworks, and high-pressure fluid handling systems. Buyers should specify their OD, wall thickness, and length requirements to match the tubing to their exact use case, as Exipei Steel Limited offers customization to meet diverse project needs.

Prior to placing an order, verify the exact chemical composition, mechanical properties, and heat treatment condition of the AISI 4140 seamless tubing with Exipei Steel Limited. Request mill test certificates and any available third-party inspection reports to confirm compliance with your project’s specifications. Ensure the supplier can provide documentation for traceability and quality assurance.
Clarify logistics details, including lead time, which may depend on the tubing’s dimensions, wall thickness, and customization requirements. Confirm the Incoterms (e.g., FOB Wuhan or CIF to your port) and payment terms, as these can impact your total landed cost. Exipei Steel Limited typically ships from Wuhan, so factor in inland transportation and port handling times.
Implement a quality control plan that includes pre-shipment inspection, dimensional verification, and mechanical property testing upon receipt. For critical applications, arrange for an independent inspection agency to conduct tests such as ultrasonic or eddy current inspection. Ensure all documentation, including material traceability records and compliance certificates, is provided to meet your quality and regulatory requirements.
