Why stainless steel is not easy to rust, and in the base body to participate in more than 12.5% chromium related, in the reductive corruption and corrosion media, chromium can make the name of steel quickly form a layer of fine coating, to avoid regular destruction of alloy, when the magnesium content is above 12.5%, composed of a layer of fine stable coating, rust treatment function caused by the magic type consolidation, Rust resistance is greatly improved, which is why the magnesium content in stainless steel needs to be more than 12%. skf bearings refer to nsk bearing standards and SKF bearing specifications. The requirements of imported overturned bearings can be seen to be universal.

The chromium content of stainless steel is about 13% -- 18%, the nickel content is about 8% -- 11%, these several chemical elements in the molting substance there is a strong anti-molting to adjust, so a part of the stainless steel to prevent REDOX reaction (rust). ina bearing Bearing tolerance is limited. They are especially suitable for bearing placement where high guiding accuracy and rate talent are required. They are especially suitable for the placement of bearings on the rear axle of equipment items. The operation contradiction of nsk bearing is not large, and the rolling friction control difference is also small. It has been promoted in the world with standardization, standardization, strong communication and communication, and can also be interchangeably applied in different well-known brands.

Rust cutting core is molting or rust, is due to the name of steel and atmospheric oxygen, water and acid, alkali, salt and other chemical substances caused by organic chemistry actual effect or photoelectric catalytic actual effect caused by fading or molting called rust, the name of the substance produced by rust is a compound.

Stainless steel is simply steel that does not rust, here; Stainless steel; Is sooner or later, is not necessarily the trend of carbon steel. In the imported bearing grinding processing, the sand wheel plate and the product contact area, consumes a lot of energy, causes a lot of cutting heat, and constitutes the part of the cutting zone instantaneously continuous high temperature. Stainless steel is not easily corroded, but not absolutely will not rust, only in the same premise and environment, compared with carbon steel is not easy to be molted with rust.
