Import 904l Fittings — Buy in Bulk from Supplier in India

904L fittings from Ashapura Steel And Alloys are austenitic stainless steel components manufactured to resist aggressive corrosion in chemical processing, oil and gas, and marine environments. The grade contains high nickel (23-28%) and molybdenum (4-5%) content, with the full composition being 0.02% carbon maximum, 19-23% chromium, 1-2% copper, and balance iron, giving superior resistance to sulphuric acid and chloride pitting. Ashapura Steel And Alloys offers flanges, bolts, tees, reducers, elbows, and couplings from their Mumbai base, with the exact dimensional ranges and pressure ratings to be confirmed directly with the supplier.

The 904L grade was developed originally for sulphuric acid service and remains the standard choice where 316L would fail prematurely due to crevice or general corrosion. Typical manufacturing conforms to ASTM A403 (wrought austenitic stainless steel piping fittings), ASTM A182 (forged flanges and valves), and ASME B16.9/B16.11 for dimensional tolerances. Weldability is excellent with matching filler metals such as ER NiCrMo-3 or ER385, though post-weld annealing is advised for maximum corrosion resistance in critical applications. Standard wall thicknesses range from Sch 5S to Sch 160, with typical butt-weld end preparations per ASME B16.25.

Buyers in chemical processing, pharmaceutical manufacturing, offshore platforms, and desalination plants source 904L fittings for heat exchangers, reactor vessels, and piping systems where 6Mo alloys are cost-prohibitive. Dairy and food processors also specify 904L for CIP (clean-in-place) systems requiring both corrosion resistance and hygienic surface finishes. Ashapura Steel And Alloys operates from Mumbai, Maharashtra, but response rate and average response time data are not available in this listing. Buyers should confirm MOQ, exact pricing, mill test certificates, and third-party inspection options before placing orders.

Ashapura Steel And Alloys is headquartered at 67, Ankush Apartment, 3rd Floor, 10th Khetwadi Main Road, Mumbai 400004, Maharashtra, India. The company is classified as an imported-tier supplier on this platform, with a harbor trust tier designation. Notably, the response rate stands at 0.00% with zero average response hours recorded, which indicates that direct communication channels may be untested or the supplier has not engaged through platform messaging. Buyers should treat this as a signal to verify responsiveness through alternative contact methods before relying on quoted timelines.

The supplier's listing mentions ISO and FDA compliance in reference to the product, though no certificate numbers, scopes, or accreditation bodies are specified. No information is provided about years in operation, annual turnover, production capacity, number of employees, or named clients. The listing does not indicate whether Ashapura Steel And Alloys holds inventory in Mumbai or operates on a make-to-order basis. Buyers should request a current ISO 9001 certificate, material test reports (MTRs) with mill references, and evidence of any FDA-related registration directly from the supplier.
