Over 20 years of special steel supplying experience and knowledge, Otai is always your No.1 reliable supplier and partner for tool steel and alloy steel. Heat Treatment for ASTM 52100 Bearing Steel. Ball-bearing races of diameters ranging from 7–15 cm made of AISI 52100 steel were used in the present study. Especially AISI 4140/42CrMo4, DIN 1.2738/P20+Ni. Anti-friction bearings 2. AISI 52100 steel is the representative of high carbon chromium bearing steel type. A chromium alloy steel traditionally used for bearings and other high-pressure applications, 52100 is excellent to use in forging, grinding, and cutlery production with a reputation for great toughness and durability on its own or forge-welded to other steels, such as 410 or 416. 79, p. 493, 1982. CTRL + SPACE for auto-complete. HIGH PERFORMANCE BEARING STEEL ESCALLOY® 52100 VAC-ARC ® 0.35 0.30 1.50 Typical Typical C Mn Si Cr Composition 1.05 GENERAL CHARACTERISTICS LESCALLOY 52100 VAC-ARC steel is a deep hardening alloy steel used for aircraft bearings and other high stressed parts where good rolling contact fatigue strength is required at operating temperatures below 400°F oundness over conventionally air … Left: Hot-rolled; Right: Spheroidized [2].As is typical for through-hardening steels, the normal sequence for hardening is austenitization, quenching, and tempering. All order process, quality control, delivery are according to ISO9001, to ensure great quality for supplied tool steel or alloy steel materials. Martempering is often used to control distortion, with temperatures of the quench oil exceeding 120°C [5]. Cold Working. Round BarFlat BarBig PlateHexagonHollow Bar/Pipe. 52100 Steel is an alloy high in carbon (more than 1% of carbon) used in industrial bearings for its excellent wear resistance and strength, today its also used in knife industry as mono steel or welded with other steels such as 410 or 416. Spherical roller bearings use two rows of barrel-shaped roller elements. cially available AISI 52100 bearing steel races. Jerrod Miller. For greater load capacity, cylindrical rolling elements are used. And also with great hot workability. AISI 52100 alloy steel is heated at 816°C (1500°F) followed by quenching in oil. Metallurgy, vol. My steel is coming from a large bearing. After quenching and tempering, its hardness would be high and uniform. Figure 3: Kinetics of carbide dissolution in AISI 52100 with a spheroidized beginning microstructure [3].Residual carbides help improve the resistance of the steel to wear. 5, pp. The greater load capacity is due to the larger contact surface area between the inner and outer rings and the cylindrical roller element. 40-47, 1989. Surface Finish: black, rough machined, turned, polished or as per given requirements. Under equilibrium conditions, AISI 52100 becomes fully austenitic in excess of 900°C; however, in practice, it is usually found that temperatures of 1,040°C for 20 minutes are necessary to dissolve the cementite [1]. 865-874, 1974. This short article on the heat treatment of AISI 52100 is by no means comprehensive, but illustrates the complexity of the manufacture of a component that is often taken for granted. : +86-769-2319-0193 Figure 2: Typical as-received microstructure of AISI 52100. AISI 52100 Alloy Steel: Typical Chemistry: Carbon: 1.00%: Manganese : 0.35%: Silicon : 0.25%: Chromium: 1.50%: Typical Applications: Bearings: Gauges: Draw Dies: Mandrels: Drills (Non-Ferrous) Taps (Hand) Forming Tools: Threading Dies (Hand) Annealed Hardness: BHN 183/212. We stock and export such bearing steels worldwide. BTW, "normalized" means to heat a material above its transformation temperature and remove it … With low distortion, reduced grinding stock is necessary. The balls allow the two rings to rotate relative to each other and support a radial load. 52100 steel composition. Fasteners and more. : +86-769-8870-5839 This steel grade 52100 steel is preferably vacuum arc re-melted to give optimum performance. C. A. Stickels, “Carbide refining heat treatment for 52100 bearing steels,” Metallurgical Trans., vol. AISI/ASTM 52100 bearing steel is a high carbon, chromium containing low alloy steel that is through hardening and noted in particular for use as bearings. There are essentially four types of roller bearings: ball bearings, cylindrical bearings (including needle bearings), spherical bearings, and tapered roller bearings. i.fb-icon-element.fontawesome-icon.fb-icon-element-1{ color: #000000;}i.fb-icon-element.fontawesome-icon.fb-icon-element-1:hover { color: #000000;}Stainless Steel, i.fb-icon-element.fontawesome-icon.fb-icon-element-2{ color: #000000;}i.fb-icon-element.fontawesome-icon.fb-icon-element-2:hover { color: #000000;}Carbon Steel, i.fb-icon-element.fontawesome-icon.fb-icon-element-3{ color: #000000;}i.fb-icon-element.fontawesome-icon.fb-icon-element-3:hover { color: #000000;}Stainless Steel, i.fb-icon-element.fontawesome-icon.fb-icon-element-4{ color: #000000;}i.fb-icon-element.fontawesome-icon.fb-icon-element-4:hover { color: #000000;}Carbon Steel, i.fb-icon-element.fontawesome-icon.fb-icon-element-5{ color: #000000;}i.fb-icon-element.fontawesome-icon.fb-icon-element-5:hover { color: #000000;}Stainless Steel, i.fb-icon-element.fontawesome-icon.fb-icon-element-6{ color: #000000;}i.fb-icon-element.fontawesome-icon.fb-icon-element-6:hover { color: #000000;}Carbon Steel.
