Material Overview & Specifications

Tatvam Overseas Inc is an authorized stockist, processor, and exporter of high-performance nickel-chromium superalloys including Inconel 625 (UNS N06625) and Inconel 600 (UNS N06600) based in Mumbai, India. We supply mission-critical components, hot-rolled plates, cold-rolled sheets, seamless pipes, and precision round bars to aerospace, marine engineering, chemical processing, and nuclear industries globally.

Inconel 625 (2.4856) is a nickel-chromium-molybdenum alloy bolstered by niobium additions. This unique metallurgical synergy produces exceptional matrix stiffening without requiring precipitation hardening, delivering outstanding tensile and yield strength from cryogenic temperatures up to 982°C (1800°F). It offers nearly complete immunity to chloride-ion stress-corrosion cracking and extraordinary resistance to severe crevice and pitting corrosion in high-salinity seawater and aggressive sour gas environments.

Inconel 600 (UNS N06600 / 2.4816) is a standard high-nickel engineering material formulated for severe chemical service and high-temperature oxidation up to 1150°C (2100°F). It exhibits remarkable resistance to dry chlorine, hydrogen chloride gas, and pure caustic alkalis, making it indispensable for heat-treating retorts, thermocouple sheaths, and furnace muffle components.

All our Inconel materials conform strictly to ASTM B443 (Plates/Sheets), ASTM B444 (Seamless Pipes), and ASTM B446 (Round Bars). We maintain complete heat traceability from premium Western European and US mills, verified by EN 10204 Type 3.1 Mill Test Certificates. Our Mumbai facility provides precision waterjet cutting, custom shearing, and third-party inspection coordination with TUV, DNV, and Bureau Veritas.

Frequently Asked Questions

What makes Inconel 625 significantly stronger than standard stainless steels? ↓
Inconel 625 derives its exceptional strength from the solid-solution hardening effects of molybdenum (8-10%) and niobium (3.15-4.15%) within its nickel-chromium matrix, requiring no heat treatment to attain high yield strength.
What is the difference in application between Inconel 600 and Inconel 625? ↓
Inconel 600 is optimal for high-temperature furnace hardware, thermal processing, and caustic alkali exposure. Inconel 625 is selected for extreme marine, seawater, subsea piping, and harsh chemical environments requiring high pitting resistance.
Can you supply small sample quantities or custom cut pieces of Inconel? ↓
Yes, given the premium value of nickel superalloys, we offer precision waterjet cutting to supply custom blanks, discs, and strips without forcing clients to purchase full plates.
Do you provide PMI test reports with Inconel dispatches? ↓
Yes, 100% of our high-nickel shipments undergo Positive Material Identification (PMI) testing with certified calibration certificates supplied alongside original mill test reports.
What export documentation is provided for international Inconel buyers? ↓
We furnish complete export documentation including commercial invoices, packing lists, Certificate of Origin (COO), and EN 10204 3.1 inspection reports.
