This 904L super austenitic stainless steel seamless pipe is engineered for highly corrosive environments in chemical processing, oil and gas, marine, and pharmaceutical industries. The material designation covers UNS N08904, EN 1.4539, and TP904L grades, with Chinese grade 015Cr21Ni26Mo5Cu2 also applicable. Available in NPS 1/8 inch to 8 inch, with outside diameters from 9mm to 219mm and wall thickness from 0.5mm to 15mm. Schedules offered include 5/5S, 10/10S, 20/20S, 40/40S, and 80/80S per ASME/ANSI B36.19M or ASME B36.10M. Maximum single length is 10 meters, with delivery conditions including bright annealed, pickled, polished, or combinations thereof.
The super austenitic composition delivers superior resistance to pitting and stress corrosion cracking through elevated chromium, nickel, molybdenum, and copper content compared to standard 300-series grades. Cold drawn and cold rolled processing methods produce the seamless structure. Surface finishes span annealing, pickling, manual polishing, and mechanical polishing to suit different service requirements. The grade is widely specified for sulphuric, phosphoric, and acetic acid environments where conventional stainless grades fail prematurely. Typical comparable products from European and Indian mills share similar chemistry limits but may differ in testing protocols and certification availability.
Applications span sulphuric acid processing plants, phosphoric and acetic acid fluid and gas transport lines, pulp and paper processing equipment, gas scrubbing plant components, seawater cooling systems, and oil refinery components. Structural and machining uses are also common. Buyers include chemical engineering contractors, marine equipment fabricators, and pharmaceutical plant constructors. Packaging is in seaworthy wooden cases, plywood boxes, steel-framed cases, or simple packaging per customer specification. The supplier is located in Shuanglin Town, Huzhou, Zhejiang Province, China, postal code 313012.

Before ordering, verify that the supplier's mill test certificates include actual chemical composition, mechanical properties, and heat treatment records for the specific heat number. Confirm that dimensional tolerances comply with the ASTM or EN standard you require, as Chinese national standards GB/T 14975 and GB/T 14976 have slightly different tolerance bands. Request a sample or third-party inspection report if your application involves pressure containment or corrosive media where material integrity is critical.
Logistics from Huzhou, Zhejiang typically export through Shanghai or Ningbo port. Confirm Incoterms (common options are FOB Shanghai/Ningbo, CIF destination port, or CFR) and whether the supplier handles export customs clearance. Payment terms, minimum order quantities, and lead times are not stated in the listing data and must be negotiated directly. Typical industry lead times for non-stock seamless pipe range from 4 to 12 weeks depending on diameter, schedule, and quantity.
On receipt, inspect for surface defects, dimensional compliance, and certificate-heat number traceability. Hydrostatic or non-destructive testing to ASTM E213 (ultrasonic) or E309 (magnetic particle) should be specified if required by your piping code. For sour service or NACE applications, request hardness testing to verify compliance with MR0175/ISO 15156 limits. Retain mill certificates for project documentation and any subsequent warranty claims.
