Pickling Ball Bearing Tube Quenched Max WT 25mm With Cold Processing Plasticity

Material GCr15 SKF3 SKF3S Bearing Steel Tube Seamless Round Steel Pipe​​

+A: After the final cold drawing process the tubes are annealed in a controlled atmosphere

1. Physical Performance

The physical properties of bearing steel are mainly examined for microstructure, decarburization layer, non-metallic inclusions, and low-power structure. Under normal conditions, it can be delivered by hot rolling annealing and cold drawing. The delivery status should be noted in the contract. The low - fold structure of steel must have no shrinkage cavity, subcutaneous bubble, white point and microporosity. The center is loose and generally loose, no more than 1.5 grade, segregation must not exceed 2. The annealing tissue of steel shall be a fine granular pearlite with uniform distribution. The depth of decarburization, non-metallic inclusions and carbides inhomogeneity should meet the relevant national standards.

2. Application

In addition to ball bearings, bearing rings, sometimes used to make tools, such as punch, measuring tools.
