Relevance
The conditions of modern industry impose special requirements on products and metal structures. It is necessary to resist the action of aggressive solutions, gases, high temperatures, huge mechanical loads. 68NKHVKTU-VI sheet can be used for a long period of time at working temperatures of up to 800ºС, in aggressive media under considerable strain. Heat-resistant and heat-resistant sheet 68NKHVKTU-VI is a prime example of the ideal price/quality ratio. Such sheet is rolled from complex-alloyed nickel alloy. Production is regulated by specifications 14-1-4470-88.

Advantages of
Diverse applications due to properties such as high strength, corrosion resistance, heat resistance. Reliability, durability and wear resistance have made this type of rolled steel very popular in many modern industries.
Application
Produce sheet parts, high-temperature installations, such as gas exhaust pipes used in petrochemical engineering. It is successfully used in the manufacture of electrical household, industrial appliances, as it actively resists oxidation in a nitrogen atmosphere, ammonia. Used in the manufacture of parts, structures, requiring a long, trouble-free operation at high temperatures and mechanical loads.
