AISI 316/316L STAINLESS STEEL BALLS. Austenitic stainless steel balls with higher corrosion resistance than AISI 304 balls. They show good toughness. AISI 316L has a lower carbon content (maximum 0,030%). Balls are provided in the passivated condition. Applications. Special bearings, pumps and valves, aerosol and dispenser sprayers.
steel (SKH4) and AISI M50 of Cr-Mo-V steel. Where heat and corrosion resistances are required, martensitic stainless steel SUS 440C may be used. Chemical components of these materials are shown along with bearings steel SUJ2 in Table 1. Their hardness at high temperature is shown in Fig. 1. The high-temperature hardness of bearing

Fully ceramic ball bearings tend to be more corrosion resistant, more rigid and lighter in weight than most steel ball bearings. Additionally, fully ceramic ball bearings are non-magnetic, which is useful for applications where this might be critical (e.g. MRI equipment). Lower coefficients of friction and higher RPMs are also possible and ...
However, significant differences occur in Rockwell hardness tests depending on whether the ball indenter that is used is made of steel or WC. In this paper, finite element analysis (FEA) is used to simulate the HR indentaiton process using steel and WC ball indenters on the same test materails under the same testing conditions.
The actual damage is caused. The rate is no more than 1%, close to 0. We have made a comparison between the cast steel ball and our forged steel ball. The results of the two are 0.9kg/t and 0.6kg/t respectively in domestic iron mines. From the data, we can see that using forged steel balls, the consumption of one ton of ore is reduced by 33.3%.

Extra Deep Drawing Steel (EDDS) Typical Rb range 15/30. For the last of the four common steel grades, there is extra deep drawing steel. This grade is for really severe drawing applications. EDDS really only allows for the product to be hit with a one or two hit draw. If it is hit more than that, then issues will be had with splitting of the steel.
Chrome Alloy Steel Balls The most common bearing alloy, are manufactured from steel of the hardening type AISI E-52100. The balls are heat treated to a hardness of 62 HRC minimum. They are strongly attracted by a magnet. Hardened Stainless Steel Balls Are widely used in bearings and valves, and are manufactured from steel AISI type 440C.

100cr6 Ball Bearings Chrome Steel Balls - Made-in-China. HS Code. 8482910000. Product Description. Chrome steel ball, as the main part of the bearing, is being widely used on the application like the automotive industry, motors, home appliances, instruments, hardware, etc. Shandong Dihui mainly produces chrome steel with sizes 0.3-120mm, with the …
Chromium increases hardness penetration, and also the toughness and wear resistance of steel. There are also traces of sulphur, manganese, iron, silicon, and phosphorous, giving the balls their hardness and exceptional surface characteristics. Chromium on steel has the ability of resisting corrosion and staining.
ASTM A240 specification covers chrome steel plates, sheets and strips for strain vessels and general purposes. Another common use for 316 and 316L stainless steel plate is within the production and use of pressure vessels, tanks, warmth exchangers, piping methods, flanges, fittings valves and pumps. Additional areas where 316 and 316L chrome ...
Hardness = 130 - (penetration/scale division) Hardness = 130 - (0.12mm/0.002mm) Hardness = 130 - 60 = 70 Loads and steel ball sizes vary dependent upon the hardness of the material: The above test process is covered by ASTM D785. The similar standard is ISO 2039-2 which differs only in the respect of not having the K scale.
