Frequently Asked Questions (FAQs)

Q1: What is Titanium Grade 7 best used for?

A1: Grade 7 is ideal for chemical processing, desalination, and marine equipment where improved resistance to reducing acids (e.g., hydrochloric acid, sulfuric acid) is required — the palladium addition boosts resistance compared to CP titanium.

Q2: Do you provide certifications and test reports?

A2: Yes. Riddhi Siddhi Impex supplies full Mill Test Certificates (MTC), heat numbers, and inspection reports on request. For critical or regulated applications ask for specific ASTM/EN/ASME certificates and NDT reports.

Q3: Can Titanium Grade 7 be welded and machined?

A3: Yes. Grade 7 is weldable using approved procedures and proper shielding gas. Machining is possible but requires appropriate tooling and cutting practices — suppliers can provide pre-machined blanks on request.

Q4: What should I specify when ordering?

A4: Specify diameter, length, finish (annealed/pickled/polished), required standard/certification (ASTM/EN/ASME), quantity, and destination city for an accurate quote and lead time.
