Import 304l Stainless Steel Fasteners — Buy in wholesale FOB from Supplier in India

Vision Alloys manufactures 304L stainless steel fasteners from an austenitic alloy containing 18% chromium, 8% nickel and maximum 0.03% carbon, a composition that minimises carbide precipitation during welding and improves corrosion resistance in welded structures. The product range spans hex bolts, hexagon head screws, socket head cap screws in full and half thread variants, hexagon wood screws, socket button head and flange screws, countersunk head cap screws, square nuts, weld nuts, nyloc nuts, flange nuts, threaded rods, dowel screws, and multiple washer types including plain, spring, countersunk and tooth lock configurations. All items are produced to DIN, ANSI and JIS dimensional standards, with metric and imperial sizes both available for global shipment from the supplier's Mumbai base in Maharashtra.

The low-carbon 304L grade offers distinct advantages over standard 304 in applications involving thermal cycles or post-weld annealing, where sensitisation around grain boundaries can otherwise compromise intergranular corrosion resistance. Typical material certification for this grade includes mill test certificates confirming chemical composition to ASTM A193 and mechanical properties per ISO 3506 Class A2-70 or A4-70 depending on procurement specification. Surface finish is typically passivated to remove free iron contamination, with thread classes 6g for bolts and 6H for nuts being standard for metric coarse series. Vision Alloys states compliance with ASTM A193 and ISO standards, though buyersqc buyers should request specific test certificates to confirm heat treatment condition and mechanical proof load values.

Primary end-use sectors for these fasteners include food processing equipment where washdown and sanitising chemicals demand crevice corrosion resistance, chemical processing plants handling chlorides and organic acids, marine hardware exposed to salt spray, and pharmaceutical manufacturing where product contact surfaces must resist rouging. The hex head and socket drive configurations suit high-torque assembly in structural and machinery applications, while nyloc and flange nut variants provide vibration resistance without separate locking hardware. Importers should confirm with Vision Alloys whether lot traceability via heat number is standard, what documentation accompanies shipment, and whether third-party inspection by agencies such as TUV or BV is available upon request.

Vision Alloys operates from premises at 6, Lad Niwas, 42/62 Ardeshir Dady Street in Mumbai 400004, Maharashtra, placing the supplier within India's principal metals trading and manufacturing corridor. The company holds a harbour trust tier on the platform, with a response rate of 0.00% and zero recorded average response hours, indicating that direct enquiry may yield limited immediate feedback and buyers should prepare for potential follow-up persistence. The listing presents an extensive fastener catalogue without stating manufacturing versus trading status, so importers should clarify whether Vision Alloys maintains in-house forging and machining capability or sources through mill relationships.

The supplier profile does not disclose year of establishment, employee count, revenue figures, named clients, or certification accreditations such as ISO 9001 or IATF 16949, all of which remain points for due diligence during qualification. What the listing does provide is broad standard coverage across DIN, ANSI and JIS fastener specifications, suggesting export market familiarity, and a material specification that correctly identifies 304L chemistry limits. Buyers should verify whether Vision Alloys can supply mill test certificates with chemical and mechanical data, whether lot traceability is maintained, and what inspection protocols apply before shipment from Mumbai port.
