Edit this paragraph chemical composition / element content (%) C: 0.95-1.05 Mn: 0.25-0.45 Si: 0.15-0.35 S: ≤0.025 P: ≤0.025 Cr: 1.40-1.65 Mo: ≤0.10 Ni: ≤0.30 Cu: ≤ 0.25 GCr15 is one of the most commonly used high-chromium bearing steel, high hardenability, a high and uniform hardness after heat treatment. Superior wear resistance GCr9, and contact fatigue strength, good dimensional stability and corrosion resistance, cold plastic deformation of medium machinability in general, poor welding, white dot formation sensitive, with a first class temper brittleness. In the manufacture of ball bearings, 12mm thickness to the outer diameter of impurities <250mm of H level to the C level of the bearing sleeve, the diameter of the ball 25.4-50.8mm; diameter <22mm roller, it can also be used in addition to withstand large Load Requirements high wear resistance high elastic limit. high contact fatigue strength of other mechanical parts and various precision measuring tools Die like. Such as a ball screw machine, turbojet nozzle aperture. Plunger valve bush and so on. Its heat treatment system as follows: annealed steel bar, wire annealing, or 830-840 degree oil quenching. Heat treatment parameters: 1. Ordinary annealed: 790-810 degree heat, furnace cooling to 650 degrees, air-cooled --HB170-207 2. Isothermal annealing: 790-810 degree heat, 710-720 degree temperature, air-cooled --HB207- 3. Normalizing 229: 900-920 degree heat, air cooling --HB270-390 4. tempering: 650-700 degree heat, air cooling --HB229-285 purposes: for the production of bearing rings and rolling elements. For example: a high-load ball bearings mechanical transmission make the internal combustion engine, electric motor car, cars, tractors, machine tools, rolling machines, drilling machines, mining machinery, general machinery, and high-speed rotation of the roller and the ring in addition to make balls. bearing ring endures, sometimes used to make tools, such as dies, measuring tools. Features: good overall performance after a good ball annealing machinability after quenching and tempering of high hardness and uniform, wear resistance and contact fatigue strength of high performance thermal processing containing more alloying elements, the price is.... Cheap .GCr15 steel is high carbon chromium bearing steel used in most production and grades, it is widely used in the world's other models bearing steel Supply: bearing steel: SUJ1 SUJ2 GCr4 GCr15 GCr15SiMn GCr15SiMo GCr18Mo G20CrMo G20CrNiMo G20CrNi2Mo G20Cr2Ni4 G10CrNi3Mo G20Cr2Mn2Mo G9Cr18 G9Cr18Mo G1Cr18Ni9Ti 13NiCr14 15NiCrMo16 -5 16NiCrMo13 20MnCr4 20MnCrNi4 20NiCrMo2 20NiCrMo7 43CrMo4 44Cr2 48CrMo4 80MoCrV42-16 100Cr6 100Cr8 100CrMn6 100CrMn7 100CrMnMo8 100CrMo7-2 100CrMo7-3 100CrMo8-3 spring steel: 65Mn 55SiMnVB 55Si2Mn 55Si2MnB 60Si2Mn 60Si2MnA 60Si2CrA 60Si2CrVA 55SiCrA 55CrMnA 60CrMnA 50CrVA 60CrMnBA 30W4Cr2VA C67S C75S C85S C100S 38Si6 38Si7 46Si7 51Si7 56Si7 65Si7 71Si7 60SiMn5 51MnV7 54SiCr6 67SiCr5100Cr2 100Cr2 various types of steel Dongguan European Union Metal Materials Co., Ltd. in east China Guangdong Dongguan Changan, mainly engaged in domestic brand tool steel, special steel, stainless steel, aluminum and other sales, processing, logistics , vacuum heat treatment and integration of metal products business.
