ASTM A249 / ASME SA249 Welded Stainless Steel Tubing
U.S.-manufactured welded stainless steel tubing for boiler, superheater, heat exchanger, and condenser service.
U.S.-manufactured A249 tubing for heat-transfer service.
ASTM A249 / ASME SA249 covers welded austenitic stainless steel tubing intended for boiler, superheater, heat exchanger, and condenser service. These applications require dependable dimensional control, material traceability, testing, and documentation aligned with the governing specification and customer purchase requirements.
Nexteel USA manufactures welded stainless steel tubing at its Munhall, Pennsylvania facility. Every inquiry is reviewed for the required grade, OD, wall thickness, length, quantity, testing, documentation, delivery requirements, and any customer-specific provisions.
When an application calls for general corrosion-resistant or temperature service rather than A249 heat-transfer service, Nexteel USA also manufactures welded tubing to ASTM A269. The governing ASTM or ASME specification should be identified on the inquiry and purchase order.

ASTM A249 versus ASTM A269
ASTM A249 / ASME SA249 is centered on welded austenitic stainless steel tubing for boiler, superheater, heat exchanger, and condenser service. ASTM A269 addresses seamless and welded austenitic stainless steel tubing for general service. The correct standard depends on the equipment, service conditions, engineering requirements, and purchase specification.
ASTM A249 / SA249
Use when the order requires welded tubing for boiler, superheater, heat exchanger, or condenser service.
ASTM A269
Use when the order requires austenitic stainless steel tubing for general corrosion-resistant or temperature service.
Match the Specification
Identify the governing standard, grade, dimensions, testing, documentation, and customer-specific requirements with the RFQ.
