The 4130 Grade/35CrMo High Strength Alloy Tubes are seamless chromium-molybdenum steel tubes engineered for applications requiring exceptional tensile strength and fatigue resistance. The material composition is Chromium-Molybdenum Alloy Steel (35CrMo equivalent to ASTM 4130), a high-strength low-alloy steel widely specified for structural components in demanding environments. These tubes are manufactured to meet ASTM A519 and DIN 41Cr4 standards, ensuring consistency in mechanical properties and suitability for oil and gas, aerospace, and automotive sectors.
The alloy’s chromium and molybdenum content enhances hardenability and temperature resistance, making it a preferred choice for welded frameworks and high-load applications. Typical industry variants include hot-finished or cold-drawn tubes, with wall thicknesses and diameters tailored to project specifications. Standard surface finishes include black, bright, or shot-blasted, with typical roughness values between 0.2 and 1.2 Ra for machined surfaces. Mill test certifications accompany each batch to verify chemical and mechanical properties.
These tubes are primarily sourced by manufacturers of pressure vessels, hydraulic systems, and structural frameworks where weight savings and durability are critical. Shandong Xinhuihe Steel Co., Ltd packages the material for secure international freight, with full documentation to support customs clearance and quality assurance. Importers are advised to confirm specific dimensional tolerances and heat treatment states, as these can vary by production batch and intended use case.

Before ordering, verify the exact mechanical properties and heat treatment state required for your application, as these can vary between production batches. Request mill test certificates and third-party inspection reports to confirm compliance with ASTM A519 or DIN 41Cr4 standards. For critical applications, specify additional testing such as ultrasonic or eddy current inspection to detect internal defects.
Confirm logistics details such as port of loading, Incoterms (e.g., FOB Qingdao or CFR destination), and lead times, which may extend to 30-45 days for non-stock sizes. Packaging should be suitable for international freight, with protection against corrosion and mechanical damage. Discuss payment terms, such as L/C or T/T, and ensure these align with your procurement policies.
Conduct quality checks upon receipt, including dimensional verification, surface inspection, and material testing if necessary. For gas or pressure applications, hydrostatic or pneumatic testing may be required. Ensure all documentation, including certificates of origin and compliance, is complete and accurate to facilitate customs clearance and traceability.
