CrN68VKTU-vi (circle, wire, tube, sheet, strip) (ep578-vi)
alloying features
Heat-resistant steel of this grade contains 68% nickel in its basis, the second place in its content is occupied by chromium, the remaining volume is occupied by iron, tungsten, aluminum and titanium. The purpose of alloying is to increase the technological properties of the products: heat resistance and heat resistance, the ability to withstand aggressive environments. Excessive alloying increases the cost of the alloy, so the process must be economical: the steel must be technologically advanced and its performance indicators must meet the required level.
Production
The steel is cast in an open-arc furnace. The rolling process takes place at a temperature of 1100°C at the beginning and 800°C at the end of the process. The steel is cooled after deformation. The first mode involves cooling in water, oil or air, while the second mode involves cooling with water, followed by holding the products for 4-4.5 hours. The bars and circles made of CrN68VKTU-vi steel are produced by hot-rolled method and by calibration - to give the products the exact outer diameter. Welding of CrN68VKTYu-vi steel is carried out using electrodes KTI-762.

Application
Power engineering industry (production of machinery and equipment for power generation), missile and aerospace engineering. The heat resistance index is the ability of the alloy to withstand mechanical stresses for a certain period of time at temperatures above 600 ° C. The maximum allowable temperature is about 1050 °C. When creating comfort and warmth in their homes, many people install fireplaces that need heat-resistant chimneys that are resistant to the vagaries of weather. Without heat-resistant pipes can not do without and in industrial production. Seams in this case, must have the same requirements for heat resistance and heat resistance, and depend on the choice of welding materials, welding modes, the presence of heat treatment at the end of the process.
