Description

35Х2ГЮФ steel is used: for the manufacture of parts by hot forming with subsequent machining: the responsible parts of machines, including precision, which should have a high Sadira and wear resistance with high strength core in the absence of high dynamic and shock loads; spindle running in plain bearings (fluid friction) and hardened steel bushings and mounted in rolling bearings; liners, pinola, worms separating couples, mandrels, screws.

Fe is the basis.
According to TU 14-1-4432-88, at the request of the consumer, the steel is supplied with a limited sulfur content at the lower limit of at least 0.020%. A technological calcium additive in the amount of 0.030% is allowed for calculation and chemical analysis is not determined. At the same time, the sulfur content is allowed not more than 0,060%. The content of residual copper, nickel, tungsten, molybdenum, titanium and permissible deviations in chemical composition in the finished rolled products must comply with GOST 4543.
