Relevance
Stainless steel wire, XN77TYR has a special place among similar products, is widely demanded in the manufacture of springs, electric heating elements, due to its qualities. The importance of stainless steel today can hardly be overestimated. The industry has received a durable, strong, corrosion-resistant material. Experiments with addition of various metals (titanium, molybdenum, niobium, cobalt) resulted in more than one hundred types of stainless steel alloys. Nickel-based steels have improved heat resistance compared to other stainless alloys and have a minimal tendency to brittle fracture at negative temperatures. Due to the chemical interaction of nickel with air, a thin film appears on the surface of the alloy, which protects the metal from corrosion.

CrN77TUR springs
Designed for operation in the temperature range of -70º +550ºС. Cylindrical, compression and tension springs are made of this alloy. Coil springs of compression and tension are subdivided by the type of loading into the first, second and third accuracy groups. The spring manufacturing process involves machining steps: grinding, milling
