The 400 Series Steel Tube from ARK Steel Tube Company is a seamless or welded ferritic and martensitic stainless steel tubing, produced to ASTM A268 and ASME SA268 standards. Supplied in grades such as TP410, TP405, TP420, TP430, TP430Ti, TP403, TP409, TP444, TP439 and TP446, it is engineered for applications demanding high mechanical strength, hardness and resistance to chloride induced pitting, crevice and stress corrosion cracking.
This tubing is manufactured with outer diameters ranging from 6 to 273 mm and wall thicknesses from 0.5 to 25 mm, suitable for heat exchangers, heaters, condensers, API service, bearing machining and petrochemical industries. The 400 series ferritic stainless steel is known for its straight chromium composition, offering moderate corrosion resistance and good formability, while martensitic grades provide higher strength and hardness through heat treatment.
Typical buyers include industrial equipment manufacturers, automotive exhaust system producers and oil and gas sector suppliers. The tubing is provided with mill test certifications, and standard packaging includes bundles or wooden crates to prevent damage during transit. Buyers should confirm surface finish requirements and whether welded or seamless production is preferred for their specific use case.

Before ordering, verify the exact steel grade and manufacturing process (seamless or welded) to ensure compatibility with your application. Confirm whether the tubing meets additional industry-specific standards beyond ASTM A268, such as API or NACE requirements, if applicable to your use case.
Logistics considerations include confirming the Incoterms (e.g., FOB, CFR) and payment terms offered by ARK Steel Tube Company. Lead times may vary depending on the order size and custom specifications, so request a production schedule to align with your project timeline. Port of loading in China should also be confirmed for shipping arrangements.
Conduct quality checks upon receipt, including dimensional verification, surface finish inspection and review of mill test certifications. For critical applications, consider third-party inspection or additional testing, such as hardness or corrosion resistance tests, to validate performance. Ensure all documentation, including packing lists and certificates of compliance, is complete and accurate.
