Frequently Asked Questions (FAQs)

1. Who is the manufacturer of titanium flanges in India?

Amardeep Steel is a leading Titanium Flanges Manufacturer in India with a comprehensive product range covering all standard types, grades, and pressure classes. The company exports to over 80 countries and carries ISO 9001, EN 10204, NACE, and NABL-approved testing certifications.

2. What is the ASTM standard for titanium flanges?

Titanium flanges are manufactured in accordance with ASTM B381 (Standard Specification for Titanium and Titanium Alloy Forgings) and the equivalent ASME SB381 designation used for pressure vessel and piping applications.

3. What grades of titanium are available for flanges?

The most common grades are Titanium Grade 2 (commercially pure, UNS R50400) for general corrosion resistance and Titanium Grade 5 (Ti-6Al-4V, UNS R56400) for high-strength applications. Grades 1, 7, 9, 11, and 12 can also be supplied on request.

4. What is the HS code for titanium flanges?

The general HS code for titanium flanges falls under HS Code 8481 (for flanges used as valves and pipe fittings) or HS Code 7326.90 (other articles of iron or steel, which may apply in some jurisdictions). Buyers should confirm the applicable code with their customs authority.

5. What is the difference between titanium Grade 2 and Grade 5 flanges?

Titanium Grade 2 is commercially pure titanium with excellent corrosion resistance and good formability, making it suitable for chemical processing and marine applications. Grade 5 (Ti-6Al-4V) offers significantly higher tensile and yield strength (950 MPa vs 344 MPa) and is preferred for aerospace, high-pressure, and structural applications where strength-to-weight ratio is critical.

6. Can titanium flanges be used in seawater service?

Yes. Titanium flanges demonstrate exceptional resistance to seawater corrosion including pitting, crevice corrosion, and biofouling, making them the standard choice for offshore oil rigs, desalination plants, and naval equipment. Unlike stainless steel, titanium does not suffer from chloride-induced stress corrosion cracking.

7. What facing types are available for titanium flanges?

Amardeep Steel supplies titanium flanges in all standard facing configurations: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ), Tongue and Groove, Large and Small Male-Female (LMF and SMF), and Lap Joint Face (LJF).
