Wire, rod, bar made of alloy 79NM
Equivalent
General characteristics
Grade 79NM consist of Ni (78,5−80%) and ferrum (the rest). It has a high electrical resistivity and firmness in an aggressive environment. For strengthening of electromagnetic properties, it must be alloyed with such elements as chrome, cuprum, molybdenum. A smelt is done in a vacuum or inert gas. A coiled bar from this steel relates to category of stainless products. A bar has a small cross-section and fixed length. A wire is widely used while welding nickel steels. A rod is used in energetic, chemical, textile and metallurgic industries.
Percentage composition GOST 10994−74
Relevance
Bar, rod, wire are the most popular products of high-nickel mill products. Nowadays, they have the widest appliaction as parts of electrotechnical constructions, which are utilized on mechanical engineering and energetics. High-nickel alloys are hard-welded and that. That is why there are made a thermal processing and the last annealing for strengthening of welds. A technical lifetime of such products is very huge, but at high temperatures (900°C) it significantly decreases.
