904L Stainless Steel — Superior Corrosion Resistance
904L (UNS N08904) is a high-alloy austenitic stainless steel with low carbon content, specifically designed to offer outstanding resistance to sulfuric acid and other strongly corrosive media. With elevated nickel, chromium, molybdenum, and copper content, 904L provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive chemical environments.
In this shipment, 904L is used for the Weldolets, Welded Pipes, 90° Elbows, and 90° Bends, all conforming to ASTM B673 Class 3 and ANSI dimensional standards — ensuring both mechanical integrity and chemical compatibility for demanding service conditions.
ASTM A182 Gr. F347H — High-Temperature Stabilized Alloy
F347H is a stabilized austenitic stainless steel (niobium/columbium stabilized) that offers exceptional resistance to sensitization and intergranular corrosion at elevated temperatures. It is the preferred choice for high-temperature applications where standard 304 or 316 grades may be subject to carbide precipitation.
The WN Flanges in this order are manufactured to ASTM A182 Gr. F347H, rated at ANSI Class #300 per ANSI B16.5, and supplied in Schedule 60 — making them ideally suited for high-temperature piping systems demanding long-term reliability.
Before shipment, all products underwent rigorous quality control procedures. Our inspection protocols covered the following key areas:
• Dimensional verification against ANSI B16.5, B16.9, and B36.19 standards
• Chemical composition analysis (PMI — Positive Material Identification)
• Mechanical property testing per ASTM A182 and ASTM B673 requirements
• Visual and surface condition inspection — no cracks, seams, or injurious defects
• Material test reports (MTRs / Mill Certificates) provided with shipment
We are proud to provide our customers with full traceability documentation, including heat number records, mill certificates, and quality inspection reports — ensuring complete confidence in product authenticity and compliance.
Extensive Product Range
Jinie offers a comprehensive catalog of stainless steel and high-alloy piping fittings — from standard grades such as 304 and 316L to specialty materials including 904L, F347H, Duplex, Super Duplex, Inconel, Hastelloy, and Incoloy. This breadth allows customers to source complex multi-material orders from a single, reliable supplier.
Strict Quality Standards
Every product we supply meets internationally recognized material and dimensional standards. Our in-house quality control team and third-party inspection partners work together to verify that all items are fully compliant before leaving our facility. Product quality certificates are issued as standard for all specialty alloy orders.
Tailored Customization Support
We understand that each customer project presents unique requirements. For this order, the 90° Bend was manufactured with a specific 5-radius (5R) centerline radius as specified by the customer, demonstrating our capacity to fulfill non-standard configurations to precise engineering requirements.
One-Stop Supply Solution
From WN Flanges and Weldolets to seamless and welded pipes, elbows, and bends — Jinie provides a complete, coordinated supply solution. Customers benefit from consolidated documentation, unified quality certification, and streamlined logistics, reducing the complexity and cost of sourcing from multiple vendors.
