Stainless Steel 321H Seamless Tubes
Kamal Piping supplies stainless steel 321H seamless tubes that are titanium‑stabilised austenitic grade. The tubes are manufactured to ASTM A213 and ASTM A312 specifications and are offered in outside diameters from 6 mm up to 324 mm. They retain mechanical strength and oxidation resistance at continuous temperatures of up to 900 °C. The supplier lists the material as SS 321H with superior creep resistance for demanding heat‑treatment environments.
Typical wall‑thickness options range from 1.5 mm to 20 mm with a tolerance of ±0.03 mm, which aligns with common industry practice for high‑temperature piping. Standard lengths are 6 m and 12 m, and the tubes are supplied seamless to avoid weld‑related weaknesses. Tensile strength for SS 321H is normally around 520 MPa, and the alloy exhibits excellent resistance to intergranular corrosion. These characteristics make the product suitable for heat‑exchanger, furnace and refinery lines where stress‑rupture performance is critical.
Primary users include aerospace manufacturers, petrochemical plants and power‑generation facilities that require reliable service above 800 °C. Kamal Piping does not publish MOQ, pricing or incoterms, so buyers should request a formal quotation to confirm trade terms. Verification of mill‑test certificates and dimensional compliance should be completed before shipment.

Sourcing Stainless Steel 321H Seamless Tubes from Kamal Piping - India Import Guide
Before placing an order, importers should request the mill‑test certificate and dimensional inspection report to confirm that the tubes meet ASTM A213/A312 tolerances and the specified OD range. Verifying the material grade, heat‑treatment condition and corrosion‑resistance data helps avoid costly re‑work once the product arrives at the destination.
Logistics for steel tubing from India typically involve FOB or CIF terms from Mumbai ports, but the precise incoterm, lead‑time and payment method must be agreed with Kamal Piping. Buyers should ask for a shipping schedule, container loading plan and any required export documentation such as a commercial invoice and packing list.
Quality assurance is enhanced by arranging a third‑party inspection at the factory or upon arrival. Checking surface condition, measuring wall thickness with ultrasonic gauges and reviewing the MTC ensures compliance with the buyer’s specifications. Maintaining records of these inspections supports smooth customs clearance and contractual compliance.
