Post Views: 7

1. Introduce

– Solid solution strengthening alloys with Ni, Cr, and Fe as the main components

– Alloy can be used in a temperature range from cryogenic to over 1095°C

– Excellent oxidation and heat resistance even at 1095℃

– UNS N06600

* 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.

* Inconel 600 vs Inconel 601

– Common points

– Differences

Features
– Inconel 600 : High strength, good machinability
– Inconel 601 : Good high temperature oxidation resistance
Content
– Inconel 600 has a higher nickel content than Inconel 601
– Inconel 601 has a higher chromium content and a small amount of aluminum added

* 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 N06600 : 06XXX : Chromium(Hastelloy, Nichrome, Inconel and etonite, some with additional element
