Alloy 600 / Inconel 600 / N06600 / 2.4816
Inconel Alloy 600 is a base alloy specially designed for use in operating conditions in cases where high resistance to corrosion is required, along with high temperature endurance - high heat resistance. By the category of application, the Russian analogues of Inconel 600 are alloys §·§¯60§£§´ and §·§¯78§´ according to GOST 5632.
Initially, Alloy 20 alloy was created for the production of products, parts, assemblies, the operation of which will be associated with contacts with sulfuric acid, with environments with its presence. However, according to the results of the work of this alloy, it turned out that it has many advantages, which expanded the scope of its use.
Alloy 20 exhibits amazing resistance to any corrosive formation in a wide variety of aggressive environments, and is not susceptible to cracking and crevice corrosion. By stabilizing Alloy 20 N08020 with niobium, carbide deposition during welding is minimized. Strength and resistance to mechanical stress also exceeds the same qualities of other materials.
Nicrofer 3620 Nb has excellent corrosion resistance in sulfuric, phosphoric and organic acids, as well as in aqueous solutions of their salts. Good stability is also maintained in nitric acid.
Due to its proven chemical composition, the alloy exhibits excellent resistance to intracrystalline corrosion and corrosion cracking. The molybdenum component of the alloys guarantees resistance to pitting and crevice corrosion.
Optimum corrosion resistance is only possible when the material to be processed is clean.
Nicrofer 3620 Nb can be welded conventionally with the same type of metal and many other metals. The following methods have been tested: DSPE, DSPE and DSPE, plasma welding, electronic welding.
When welding with shielding gas, the pulse technique is preferred.
The following welding consumable is recommended:
Nicrofer S6020 W.-Nr. 2.4831
For electronic welding
W. Nr. 2.4609
