Inconel 600 is a solid-solution nickel-chromium alloy renowned for its outstanding resistance to oxidation, corrosion, and high-temperature environments. It primarily consists of nickel (72%), chromium (14-17%), and iron (6-10%), with small amounts of other elements such as manganese, silicon, carbon, sulfur, and copper.
Inconel 600 pipe fittings are readily fabricated and welded using conventional methods. Proper welding procedures and filler materials compatible with Inconel 600 should be employed to ensure the integrity and performance of the welded joints.
Inconel 601 buttweld fittings are components used in piping systems that require joining pipes and changing their direction. These fittings are made from Inconel 601, a nickel-chromium alloy known for its exceptional resistance to high-temperature oxidation and corrosion.
Inconel 601 is primarily composed of nickel, chromium, and iron, with additions of aluminum for enhanced resistance to oxidation and sulfur for improved carburization resistance. This composition provides excellent mechanical strength and resistance to high-temperature environments.
Inconel 601 exhibits good weldability using conventional welding techniques such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and shielded metal arc welding (SMAW). Proper welding procedures and filler materials compatible with Inconel 601 should be used to ensure the integrity of the welded joints.
Inconel 625 buttweld fittings are components used in piping systems that require joining pipes and changing their direction. These fittings are made from Inconel 625, a nickel-chromium-molybdenum alloy known for its exceptional corrosion resistance and high-temperature strength.
Inconel 625 is primarily composed of nickel, chromium, and molybdenum, with additions of niobium, iron, and other alloying elements. This composition provides excellent resistance to oxidation, pitting, crevice corrosion, and chloride stress corrosion cracking.
Inconel 625 buttweld fittings are manufactured in compliance with industry standards such as ASTM B366 for nickel alloy pipe fittings. These standards specify the dimensions, tolerances, materials, testing procedures, and marking requirements for the fittings.

Inconel 600, 601, and 625 buttweld fittings are all nickel-based alloys known for their high-temperature strength and corrosion resistance.
Inconel 600 offers excellent oxidation resistance, while Inconel 601 excels in carburization environments.
Inconel 625 provides superior corrosion resistance in various conditions, including seawater.
The choice between them depends on specific application needs, such as temperature, corrosion environment, and mechanical properties required. All three alloys offer good weldability for fabrication.
