Inconel 600 alloy is nickel - chromium - iron based solid solution strengthened alloy, with good high temperature corrosion resistance and oxidation resistance, excellent cold and hot working and welding properties, under 700℃ with satisfactory thermal [TJC STEEL]strength and high plasticity.

 

Product introduction

The alloy can be hardened by cold working and can also be joined by resistance welding, dissolution welding or brazing, making it suitable for making anti-oxidation parts that can withstand low loads below 1100 ° C.

 

Application Field

● Thermocouple sleeve in corrosive atmosphere

● Vinyl chloride monomer production: resistance to chlorine, hydrogen chloride, oxidation and carbonization corrosion

Conversion of uranium oxidation to hexafluoride: Resistant to hydrogen fluoride corrosion

● The production and use of corrosive alkali metals, [TJC STEEL]especially in environments where sulfides are used

● Titanium dioxide by chlorine gas process

● Organic or inorganic chloride and fluoride production: resistance to chlorine and fluorine gas corrosion

● Nuclear reactor

● Curved neck flask and parts in heat treatment furnace, especially in carbonization and nitriding atmosphere

● The catalytic regenerator in petrochemical production is recommended to use alloy 600H for long service life in applications above 700℃.

Preparation of Titanium Dioxide:

● Has a good resistance to reduction, oxidation, nitriding medium corrosion performance

● It has good resistance to stress corrosion cracking at room temperature and high temperature

● Has a good resistance to dry chlorine gas and hydrogen chloride gas corrosion performance

● Excellent mechanical properties z at sub-zero, room temperature and high temperature

As the control of carbon content and grain size has good [TJC STEEL]creep resistance and fracture strength, it is recommended to use the working environment above 700℃.

Filling Metal

The Following Filler Metals Are Recommended For Welding:

Tungsten Electrode Gas Welding	Nicrofer S 7020	AWS A5.14: ERNiCr-3
Metal Electrode Gas Shielded Welding		AWS A5.11: ENiCr-3
For Alloy 600h At High Temperature (Approx. 900℃), The Following Solder Is Recommended:
Tungsten Electrode Gas Welding[TJC STEEL]	Nicrofer S 6020	AWS A514, ERNiCr-3
or		AWS A514, ERNiCrFe-5
Tungsten Electrode Gas Welding		AWS A5.11, ENiCr-3
or		AWS A5.11, ENiCrFe-5
Argon Arc Welding Is Recommended To Obtain The Best Corrosion Resistance

 

To obtain optimum corrosion resistance, argon arc welding is recommended for the Inconel 600 suitable any traditional welding process with the same material or other metal welding, such as gas tungsten arc welding, plasma arc welding and manual arc welding, metal inert gas protection welding, melting inert gas protection welding, including pulsed arc welding is the preferred [TJC STEEL]solution.When manual arc welding is used, it is recommended to use (Ar+He+H2+CO2) multi-component shielding gas.

Incoloy 825 welds must be annealed and cleaned of stains, dust, and marks using a stainless steel wire brush.In order to obtain the best quality of the root weld, care must be taken (argon 99.99) so that no oxide is produced after the root weld is completed.The color produced by the welding heat affected zone should be brushed away with the stainless steel brush when [TJC STEEL]the welding zone is not cooled.
