ASTM, AISI, SAE bearing steel grades wihometals

ASTM A866 Medium Carbon Wear-Resisting Bearing Steel. The steel grades consist of five digits, the first digit is 5 for chromium steel, the second digit for chromium content, and the last three digits for average carbon content. For example, 52100 bearing steel with a carbon content of 0.95% ~ 1.10% and chromium content of 1.30% ~ 1.60% Bearing Steel - Grades and Products Range - Sales Bearing Steel:Product Range of Bearing Steel Grades .

China bearing steel grades include G8Cr15, GCr15, GCr15SiMn, GCr15SiMo and GCr18Mo. Bearing steel, also known as high carbon chromium steel, has a carbon content of about 1% and a chromium content of 0.5% to 1.65%. This steel has high and uniform hardness and wear resistance, as well as high elastic limit.

Thank you. Jack, Louisiana. Dear Jack, ABEC Grade 5 bearings are actually better than Grade 3 and Grade 3 was the minimum grade recommended in the article, so the bearings you DIN 1.3505 Material 100Cr6 Bearing Steel Equivalent

  • 100Cr6 SteelDatasheet & SpecificationEquivalent GradesDIN EN 1.3505 material (100Cr6 steel)is an ISO and European EN standard alloy bearing steel grade. It has good toughness, good tempering stability, and small deformation during heat treatment. After quenching and tempering, 100Cr6 material has high hardness and uniformity, good wear resistance and high contact fatigue strength.13. BEARING MATERIALS13.1 Materials for Bearing Rings and Rolling Elements Primarily, high carbon chromium bearing steel (Table 13.1) is used for the bearing rings and rolling elements. Most NSK bearings are made of SUJ2 among the JIS steel types listed in Table 13.1, while the larger bearings generally use SUJ3.

Steel Standards - ASTM InternationalASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.

Bearing materials - NSK10. Bearing materials 10.1 Comparison of national standards of rolling bearing steel The dimension series of rolling bearings as mechanical elements have been standardized internationally, and the material to be used for them specified in ISO 683/17 (heat treatment, alloy, and free cutting steels / Part 17 ball and roller bearing steels). Bearing Materials - Ceramics, Chrome Steels, Stainless Bearings made from medium or low carbon alloy steel material are typically called semi-precision or commercial grade bearings. The typical materials are AISI8620 or AISI4320. The inner and outer rings are surface hardened in a heat Bearing Steel - an overview ScienceDirect TopicsBall-bearing steels are an outstanding example to discuss steel cleanliness as in this application the relation between cleanliness and fatigue properties has been clearly established [47].The total oxygen levels in ball-bearing steels produced at Ovako Steel Hofors (former SKF steel) via the acid open hearth process (1964) and later via an electric arc furnace and an ASEA-SKF ladle Steels for bearings - University of CambridgeLean Steels:Microstructure. Steels with carbon concentrations in the range 0.8-1.1 wt% and the total substitutional solute content less than 3 wt%, designed originally for machining tools, have historically dominated the mass market for bearings [ s10, 9].They can be made martensitic by quenching in oil or salt, from a temperature where the material is mostly austenite. Ball Grades New Hampshire Ball Bearings, Inc.Ball Grades. Balls are manufactured to the precision requirements noted in ANSI/ABMA Std. 10A for steel balls and ASTM F2094 for ceramic balls. These standards require that balls meet the limits for ball diameter, spherical form, and roughness noted below for each grade level. Lower-grade numbers denote more precise balls, which help to improve Ball Size Grade Tolerance Definitions Hartford TechnologiesHartford conforms to precision ball standards (including ABMA Standard 10, ISO 3290 & DIN 5401) that dictate the industry standards of precision balls. 52100 / E51200 Bearing Steel, High Carbon-Chromium - Description. High carbon, high chromium, aircraft quality bearing steel. This material develops high hardness, and exceptional resistance to wear and abrasion. In smaller sections it has a high compression strength. Furnished in the spheroidized annealed condition in order to provide the best possible machinability. 52100 Vac Melt.
