Basic Requirements for Bearing Steel
According to the basic requirements for bearing steel , the following basic requirements are submitted to the metallurgical quality of bearing steel. 1. Strict Chemical Composition Requirements Generally, bearing steel is mainly high-carbon chromium-bearing steel. Chromium can improve thermal treatment performance, organize uniformity, ignition stability, and improve the rust-proof and grinding performance of steel. Only by strictly controlling the chemical ingredients in the bearing steel can the tissue and hardness of the bearing performance be obtained through thermal processing processes. 2. Higher Dimensional Accuracy Requirements For the bearing steel for forging on a high-speed forged machine, it should have higher requirements for its size and accuracy. Rolling shaft bearing steel requires high size and accuracy because most of the bearing parts must be formed by pressure. If the size of the steel is not high, it cannot accurately calculate the size and weight of the feeding, a...
