The elastic properties of a precision material are quite important characteristics that ensure a reliable and long-term operation of such raw materials even with a significant change in temperature conditions. Therefore, the alloy 68НХВКТЮ with a regulated index of elasticity is quite popular in many branches of the industrial complex.
Application
Most often, this material is used as raw material in the production of high-quality long products, from which in turn, elastic semi-finished products with high sensitivity are manufactured. This product can work perfectly in a fairly wide temperature range from minus one hundred and ninety six to five hundred degrees plus. Such features allow the use of varietal products labeled with 68NHVKTU in various climatic conditions without loss of performance. Due to the high heat conductivity, electrical resistance and many other useful qualities, precision materials of this type are used in many areas of modern industry. Radio engineering, automotive, electrical engineering, aviation and many other spheres can not do without accurate materials, in which there are no harmful additives and whose composition is regulated by regulatory documentation.

Weldability indexes
| The alloy has limitations on weldability | The welding process requires some preliminary preparation (warming the contacting surfaces to one hundred and one hundred and twenty degrees and subsequent heat treatment of the seam zone) |
| The alloy has no weld constraints | No additional operations are required |
| Hard to weld material | It is necessary to warm the contacting surfaces to two hundred or three hundred degrees, the subsequent annealing and heat treatment after the end of the welding process |
