Features:
The overall performance of SKF3 bearing steel is good. After quenching and recovery, the hardness is high and uniform, the wear resistance is good, and the exposure to fatigue is high. The steel has good heat treatment and good cutting ability after shaking.
SKF3 bearing steel has good toughness, good ignition stability, and small deformation during heat treatment. The carbides in the steel are evenly distributed, which is not easy to precipitate the carbonization network, and it is easy to eliminate active fires. It can eliminate mesh and coarse carbide tissue through active fire.
When the surface residual carbon content of SKF3 bearing steel is 0.6% 0.7% deoxidation layer, due to the reduction of carbides, the overheating sensitivity of the surface layer increases. After normal heating and quenching, the surface hardness can still reach HRC5860, but its bending strength is reduced by 40% and 50%. The grain size of the surface layer reaches 7 and the heart is 10.
SKF3 bearing steel has good forging properties. Due to the ease of deactivation, atmospheric furnaces need to be heated or protected in a neutral atmosphere. Forging heat conditioning treatment can make gene recovery good, simplify the process, save time and save money. It has good cutting and processing properties and ideal residual heat treatment structure. The heating temperature of the steel is 320°C, the quenching is better than that of chromium steel, and the hard depth of the oil is 4050mm.
Zero-zero quenching and toughness of SKF3 bearing steel can eliminate early failures of steel wire friction plates due to conventional quenching, heating and oxidation and decoupling. Or a Mataite like a fine needle, with good toughness.
Utilization:
SKF3 bearing steel can be used in the manufacture of quantities, molds and woodworking tools. Making internal combustion engines. Electric locomotives, machine tools, tractors, steel rolling equipment, drilling machines, railway vehicles, as well as mining machines, such as steel balls, rollers and shafts on drive shafts.
