Inconel 625 Forged Fittings are among the most reliable alloys for use in offshore and sea water applications, as well as in chemical industries. Its strength is in the synergistic effect of the alloying elements niobium and molybdenum together on the nickel-chromium matrix, which is the basis of this alloy, UNS N06625 / DIN 2.4856. This saves time for extra heat treatment, and provides outstanding tensile strength, creep-rupture resistance, resistance to pitting, crevice corrosion and stress corrosion cracking. Alloy 625 Forged Fittings are non-magnetic and can be welded using all conventional welding methods, and are capable of high performance from cryogenic to 982°C.
Amardeep Steel Centre is one among the foremost manufacturers and exporters of ASTM B564 Inconel 625 Forged Fittings in India. We offer Inconel 625 Socket Weld Fittings and Inconel 625 Threaded Fittings 1/8" to 4" NB Class 2000 to 9000 LBS, including EN 10204 3.1 test certificate and PMI report.

Frequently Asked Questions (FAQs)
Q1. Why is Inconel 625 preferred in offshore and marine applications?
Inconel 625 Forged Fittings offer exceptional resistance to seawater corrosion, pitting, and crevice corrosion due to its high Mo and Nb content. It also resists low macrofouling rates, making it ideal for subsea and marine systems.
Q2. Is Inconel 625 weldable?
Yes. Inconel 625 Forged Fittings can be welded using all conventional welding processes. Its high niobium content stabilizes the weld zone, eliminating intergranular corrosion in the heat-affected zone.
Q3. What pressure ratings are available for Inconel 625 Forged Fittings?
Inconel 625 Forged Fittings are rated at 2000 LBS (Threaded), 3000 LBS, 6000 LBS, and 9000 LBS (Socket Weld) in sizes from 1/8" to 4" NB per ASME B16.11.
Q4. What temperature range does Inconel 625 cover?
Inconel 625 Forged Fittings perform from cryogenic temperatures (-196°C) up to 982°C, retaining mechanical strength and corrosion resistance across this entire range without heat treatment.
