UNS N10276 Hastelloy C276 Spectacle Blind Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS N10276 Hastelloy C276 Spectacle Blind Flanges in Mumbai.
Hastelloy C-276 (UNS N10276) spectacle blind flanges from Synergy Engineering Solution & Exporter are engineered for the most corrosive industrial environments. Manufactured from premium C-276 alloy, these spectacle blinds combine excellent resistance to pitting, crevice corrosion and stress-corrosion cracking across a wide range of media — including chlorides, strong oxidizers and reducing agents. Synergy produces spectacle blind flanges to meet international flange standards and dimensional tolerances, ensuring compatibility with pipework used in chemical processing, petrochemical, desalination, offshore, power generation and pharmaceutical plants.
Our manufacturing process emphasizes traceability, metallurgical integrity and precise machining. Each spectacle blind flange is produced from certified UNS N10276 plate or forgings, heat-treated where required, and finished to a smooth, burr-free surface to guarantee a reliable sealing face. Typical finishes and options supplied include raised face (RF), ring type joint (RTJ), and full face configurations, plus custom drilling or marking. Synergy follows strict QA/QC protocols — including material test certificates (MTC), PMI verification on request, dimensional inspection and pressure fit checks — to ensure every item shipped meets client and regulatory requirements.
Stocking and lead-time advantages are a core benefit when you source from Synergy. The company maintains strategic inventory for common sizes and pressure classes, enabling rapid dispatch to key markets in the Middle East (Oman, Qatar, Saudi Arabia, UAE, Kuwait), Europe (Spain, Germany), North America (USA, Canada), and across Africa. For special alloys, large diameters or non-standard configurations, Synergy offers batch production and priority export consolidation with secure packaging and documentation (commercial invoice, packing list, MTC, COA, and export paperwork) to simplify customs clearance and onsite logistics.

Performance and application guidance: Hastelloy C-276 spectacle blind flanges are the preferred choice where mixture of oxidizing and reducing chemicals, high chloride environments, or variable temperatures make ordinary stainless steels unreliable. They perform well in flue gas desulfurization (FGD), chlorine production, acid pickling circuits, and waste treatment plants. For engineers, Synergy provides application support including flange selection (material/face type), torque and gasket recommendations, and compatibility consultation to extend service life and avoid costly downtime.
Why choose Synergy Engineering Solution & Exporter: beyond high-quality fabrication, Synergy combines metallurgical expertise with export experience — offering competitive pricing for bulk projects, flexible MOQ for small maintenance orders, and reliable documentation for international procurement. Their global logistics partners and consolidated export lanes reduce transit time and risk for customers in the GCC, Europe, North America and Africa. Technical service, on-time dispatch, and after-sales support are highlighted in customer feedback as reasons clients repeatedly source Hastelloy C-276 spectacle blinds through Synergy.

Frequently Asked Questions (FAQ)
Q1: What makes Hastelloy C-276 suitable for spectacle blind flanges?
A: Hastelloy C-276 offers excellent resistance to pitting, crevice corrosion and stress-corrosion cracking across mixed oxidizing and reducing environments (chlorides, wet chlorine, organic acids, etc.). This makes it ideal for spectacle blinds used in corrosive piping isolation and testing duties. Always confirm application conditions with Synergy's technical team. :contentReference[oaicite:4]{index=4}
Q2: Which flange face styles are available?
A: Common face types supplied include Raised Face (RF), Full Face (FF), and Ring Type Joint (RTJ). Special drilling or machining can be supplied per customer request.
Q3: What documentation is supplied with shipments?
A: Standard documentation includes Commercial Invoice, Packing List, and Material Test Certificate (MTC). EN 10204 3.1 / 3.2 certificates, PMI reports and third-party inspection reports can be provided on request to meet buyer/sponsor requirements.
Q4: Are Hastelloy C-276 spectacle blind flanges weldable and machinable?
A: Yes — C-276 is readily weldable by common methods and is normally supplied in solution-annealed condition. It is also machinable, but care is needed due to work-hardening characteristics; recommended tooling and parameters should be followed. :contentReference[oaicite:5]{index=5}
Q5: How should I specify material on a purchase order?
A: Typical PO line: "Spectacle Blind Flange, Hastelloy C-276, UNS N10276, ASME/ANSI B16.5 (size/pressure), face type RF, material to be supplied with MTC EN 10204 3.1, heat no. & traceability." For custom needs include finish, marking, packaging and inspection requirements.
In order to alter the physical and mechanical characteristics of metal without altering its original shape and size, we offer a variety of heat treatment services, including hydrogen heat treatment, HIC testing, blasting and painting, cutting, arc welding, epoxy cutting, PMI testing, hydro testing, NACE testing, and SSC testing. Although heat treatment is frequently linked to a metal's increased strength, it can also be used to change specific manufacturability goals, such enhancing machinability, formability, ductility, etc. The metal and heavy manufacturing sectors use our services. Customers have expressed great pleasure with our services' precision, efficacy, cost, and prompt delivery.
