According to various types of bearing steel maintenance methods, it can be divided into two categories: micro defects and micro defects. Strictly control these skill indicators and make them as much as possible; it is the primary content of all kinds of bearing steel skill requirements. These are common in steel. Shortcomings. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. Micro-disadvantages: The micro-disadvantages of steel include all kinds of non-metallic inclusions, carbon segregation, carbide network and strip, and annealing unevenness in the steel that can be found under the optical microscope.
All kinds of bearing steel special standards have strict demarcation of these shortcomings.
2, micro-disadvantages: including appearance appearance can be found in the pitting, cracks, folding, cracking, scratching, crusting and slag inclusions and low-double pickling can be found in the shrinkage hole, subcutaneous bubbles, white spots, over-burning The center is lax, usually slack and segregation, surface decarburization, etc. These are the primary shortcomings that affect the purity and uniformity of steel.
