USA Piping Solution is a reliable manufacturer and supplier of Stainless Steel 430 Seamless Tubes that has a trusted history in providing high quality ferritic stainless tubing to the demanding industrial market in the USA and all over the globe. Our SS 430 Seamless Tubes (UNS S43000 / DIN 1.4016 / ASME SA268 TP430) are seamless tubes that are produced without a longitudinal weld seam and therefore, have inherent structural uniformity, which makes them suitable for use where consistent wall thickness, superior roundness and absence of discontinuities associated with the seam is critical. They have excellent oxidation resistance and resistance to mild corrosive environments, good formability and useful mechanical properties in an annealed state. They are offered in a wide range of dimensions from 1/2 NB to 18 NB, and are available in different wall thicknesses as well as by custom length and size upon request. All Stainless Steel 430 Seamless Tubes are provided with complete EN 10204 3.1 mill test report.

Frequently Asked Questions (FAQs)
Q1: We are procuring SS 430 seamless tubes for a heat exchanger project. Can you confirm hydrostatic test
pressure and provide certified test reports for our ASME code inspector?
A: Yes. We hydrostatically test all SS 430 seamless tubes per ASTM A268 and issue EN 10204 3.1 MTRs. ASME SB / SA-certified material and additional ASME code inspector hold-point documentation can be arranged at the time of order.
Q2: Our food processing line requires SS 430 seamless tubes with a smooth bore and no pits.
What surface finish and bore condition can you supply?
A: We supply SS 430 seamless tubes with bright annealed bore, surface roughness Ra less than 0.4 micrometres, in pickled and passivated finish. Electropolished inner bore is available for hygienic applications. Certificates confirming finish are included.
Q3: What OD and wall thickness tolerances should we design to for SS 430 seamless tubes in an
automotive exhaust sub-assembly?
A: Per ASTM A268, OD tolerance is typically plus or minus 0.1 mm for small sizes. Wall thickness tolerance is plus 22% / minus 0%. We can supply to tighter tolerances on request. Our tech team can assist with your design drawing review.
Q4: Do you offer SS 430 seamless tubes in half-hard or cold-drawn condition suitable for precision machined components?
A: Yes. Cold Drawn Welded (CDW) and cold-drawn seamless options in SS 430 are available for precision-machined parts. Tighter OD tolerances of plus or minus 0.05 mm and improved surface finish are achievable. Please share your drawing specifications.
Q5: We need ASTM A213 TP430 seamless tubes for a superheater bundle. Can you supply in continuous
lengths over 9 metres with straightness within 3 mm per metre?
A: Yes. We supply ASTM A213 TP430 seamless tubes in lengths up to 12 metres with straightness within 3 mm per metre as standard. Bundle lengths and specific heat-lot traceability are available. Contact us with your complete project specification.
