Analysis of bearing steel

    Today we mainly introduce two common steels.HONBbearing07
 
45——High-quality carbon structural steel, the most commonly used medium-carbon quenched and tempered steel
 
    Main features: The most commonly used medium-carbon quenched and tempered steel, with good comprehensive mechanical properties, low hardenability, and easy to crack during water quenching. Small parts should be quenched and tempered, and large parts should be normalized.
 
    Application examples: Mainly used to manufacture high-strength moving parts, such as turbine impellers, compressor pistons, shafts, gears, racks and worms. Pay attention to preheating before welding and annealing for stress relief after welding.

40Cr-one of the most widely used steel grades, belongs to alloy structural steel
  
    Main features: After quenching and tempering treatment, it has good comprehensive mechanical properties, low-temperature impact toughness and low notch sensitivity, good hardenability, high fatigue strength when oil-cooled, and easy parts with complex shapes when water-cooled. Cracks occur. Cold bending plasticity is moderate, good machinability after tempering or quenching and tempering, but poor weldability, and easy to crack. It should be preheated to 100~150℃ before welding. Generally used in quenched and tempered state, it can also be used for carbon nitrogen Co-permeation and high-frequency surface hardening treatment.
 
    Application example: After quenching and tempering, it is used to manufacture medium-speed and medium-load parts, such as machine tool gears, shafts, worms, spline shafts and thimble sleeves. After tempering and high-frequency surface quenching, it is used to manufacture high hardness and resistance Grinding parts, such as gears, shafts, spindles, crankshafts, spindles, sleeves, pins, connecting rods, screws and nuts, intake valves, etc.; after quenching and tempering at medium temperature, they are used to manufacture heavy-duty, medium-speed impact Parts, such as oil pump rotors, sliders, gears, spindles and collars, etc.; after quenching and low temperature tempering, they are used to manufacture heavy-duty, low-impact, and wear-resistant parts, such as worms, spindles, shafts and collars, etc.; carbon After nitriding treatment, transmission parts with larger size and higher low-temperature impact toughness are manufactured, such as shafts, gears, etc.
