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.
Gcr15 (AISI 52100) is an excellent general purpose bearing steel. Due to its excellent hardness and wear resistance, it exhibits good fatigue life in rolling element bearings. However, the corrosion resistance of chrome steel is poor because of the low chromium content. Bearing Materials AST BearingsStainless steel materials are used to make bearing components because it is more resistant to surface corrosion due to the higher content of chromium (~18%) with the addition of nickel. The chromium reacts with oxygen to form a layer of chromium oxide on the surface, creating a passive film. Martensitic Stainless Steel Bearings- AISI 440C Bearing Materials:Choosing the Right Alloy to Meet Your Feb 01, 2016 · This metal boasts an improved corrosion resistance compared to AISI 440C and can be hardened by heat treatment and used for heavy-load and high-rotation applications not suitable for AISI 304 stainless steel ball bearings. AISI 630 stainless steel ball bearings are suitable for LCD and semiconductor manufacturing equipment, metal plating equipment or film manufacturing equipment.

9Cr18Mo bearing steel with polished finish plate is a high carbon chromium stainless steel used for making bearing rings and rolling bodies. Used as mechanical cutting tool, cutting tool, surgical blade, parts of high wear - resistant equipment. In standard GB/ t1220-2007, the brand of 9Cr18Mo has become 102Cr17Mo. Chemical composition Stainless Steel - Material Science News Materials Sep 13, 2001 · The 316 family is a group of austenitic stainless steels with superior corrosion resistance to 304 stainless steels. They also have excellent toughness and can be used in the food, marine, chemical and architectural fields. Other applications include fasteners and Stainless Steel Grades - Continental Steel & Tube Companya higher grade of cutlery steel, with more carbon in it, which allows for much better edge retention when the steel is heat treated properly. It can be hardened to Rockwell 58 hardness, making it one of the hardest stainless steels. Also known as "razor blade steel". Available in three grades 440A, 440B, 440C (more common) and 440F (free
ASTM'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. TYPES OF STAINLESS STEEL 304, 316 and 430 - Cleanroom Stainless steel is not a single alloy, but rather the name applies to a group of iron-based alloys containing a minimum of 10.5% chromium. Other elements are added and the chromium content increased to improve the corrosion resistance and heat-resisting properties, enhance mechanical properties, and / or improve fabricating characteristics. There are over 50 stainless-steel grades that were Types of Metals to Choose for Machining 2020 [Easy How to 52100 is a common material for making ball bearings These high carbon steels have materials like Chromium added to improve their mechanical properties. It was developed for bearing applications in 1905 and continues to be the most-used bearing steel. Common Uses:Ball Bearings in
Chromium steels are types of steel, with which iron can be alloyed with chromium. Colloquially the term is often used interchangeably with the word stainless steel. In principle, chromium does not have to be necessarily contained in stainless steel, but chromium is one of the most common alloying elements in stainless steel grades and is contained in most commercially used stainless steel grades.
