STAINLESS INDIA stands as a prominent manufacturer, stockist, and exporter of Alloy
Steel Flanges, providing high-quality industrial flanges designed for
high-temperature, high-pressure, and corrosive environments. Our Alloy Steel Flanges
are produced in accordance with ASTM A182, ASME B16.5, B16.47, BS, DIN, and EN
standards, guaranteeing outstanding durability, mechanical strength, and thermal
stability. We offer flanges in grades F5, F9, F11, F22, F91, and various other
chrome-moly specifications.
We provide a diverse selection of flanges including Weld Neck, Slip-On, Blind,
Socket Weld, Threaded, Lap Joint, Long Weld Neck, Orifice, and Custom CNC-Machined
Flanges across a broad spectrum of alloy steel grades. We also manufacture
Alloy Steel Pipes,
Alloy Steel Butt Weld Fittings,
Alloy Steel Forged Fittings,
Alloy Steel Round Bars, and
Alloy Steel Sheets & Plates
to provide complete piping solutions for industrial projects.
These flanges find extensive application in the power generation, oil & gas,
petrochemical, and refinery sectors worldwide.
Precision-forged and CNC-machined to stringent tolerances.
Outstanding creep resistance and stability at elevated temperatures.
Resistant to oxidation, carburization, and thermal fatigue.
100% Radiography, Ultrasonic, and PMI tested.
Heat-treated to enhance mechanical properties and hardness.
Available in RTJ (Ring Type Joint), RF (Raised Face), and FF (Flat Face).
ISO, IBR, PED, and CE certified in-house manufacturing and quality control.
CNC machining and bespoke manufacturing services available.
Quality testing includes UT, RT, PMI, and hardness assessments.
Complete material traceability accompanied by detailed test reports.
Supplying to EPC contractors, refineries, and power projects globally.
Extensive inventory with prompt delivery and flexible MOQs.
We export to more than 70+ countries:
USA • UK • Germany • Italy • UAE • Saudi Arabia • Qatar • Oman • Kuwait • Singapore • Malaysia • Indonesia • Australia • South Africa • Brazil • Mexico • India
Selecting the correct Alloy Steel Flange depends on operating pressure, temperature, corrosion conditions, pipe size, pressure class, facing type, and applicable international standards. Our engineering team assists EPC contractors, refineries, power plants, petrochemical facilities, offshore projects, and industrial manufacturers in selecting the most suitable flange solution for long-term performance.
Every Alloy Steel Flange undergoes dimensional inspection, visual inspection, PMI testing where required, hardness testing, ultrasonic testing, and documentation verification before dispatch. Material traceability is maintained throughout production to ensure compliance with international quality requirements.
Products are packed in fumigated wooden boxes, wooden pallets, or export-worthy packaging with proper marking, heat number identification, moisture protection, and complete export documentation including EN 10204 3.1 Mill Test Certificates and third-party inspection reports whenever required.
For complete piping projects, explore our range of Alloy Steel Pipes, Alloy Steel Butt Weld Fittings, Alloy Steel Forged Fittings, Alloy Steel Round Bars, and Alloy Steel Sheets & Plates. These products are manufactured to international standards and are available with complete material traceability and inspection documentation.
