Inconel 601(Ni-Cr)

Post Views: 7

1. Introduce

– Ni-Cr alloy with high Cr content and some Al, which provides excellent resistance to high temperature oxidation and corrosion

– Excellent oxidation resistance and high temperature material properties up to a temperature range of 1250℃

– High temperature mechanical properties superior to Inconel 600 due to increased Cr and Al content

– UNS N06601

* Inconel

Features
– Resists oxidation and submersion in oxidizing and sulfurizing atmospheres above 900℃
– Non-corrosive to organic and salt solutions
– Excellent mechanical properties such as tensile and yield strength up to about 600℃
Applications
– High temperature heat resistant equipment(Heat treatment furnace, boiler, jet engine parts, electric heater parts)
Types
– Incoenl 600/601, Inconel 625, Inconel 690, Inconel 718, Inconel 718+, Inconel X-750, etc.

* UNS

Abbreviation for Unified Numbering Systems for Metals and Alloys
Unified unique numbering system for metals and alloys
A representative number that is compatible with metals and alloys defined in many material-related codes such as ASTM, AISI, ASME, AWS, etc.

* N : Nickel and Nickel Alloys

* UNS N06601 : 06XXX : Chromium(Hastelloy, Nichrome, Inconel and etonite, some with additional element
