The full name of bearing steel is called rolling bearing steel; it has high compressive strength and fatigue limit; high hardness; high wear resistance and certain resistance; good hardenability; extremely strict control of sulfur and phosphorus; it is a high-grade high-quality steel; Can do cold touch tool steel. Specific gravity: 7.81 /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
ㄒ唬┲岢 侄驮煳 .. 1) Initial forging temperature: 1150 (1120) final satin temperature: 850 (800) degrees.
.2) Disadvantages of the excavation table before casting; heat up as soon as possible after preheating.
.3) During warm processing; blue-brittle area of ​​200-400 degrees should be prevented. During hot processing; it should be prevented from entering high-temperature brittle area (greater than 1250). It should be prevented from entering hot fragile area (800~-950 degrees).
.ǘ┒ǘ┒ǘ┒笕.1) Pre-heat treatment after forging (spheroidizing annealing) End heat treatment (quenching + low temperature tempering)
.2) Spheroidizing annealing intention: lowering the hardness; facilitating processing; preparing for quenching.
Spheroidizing annealing process: heating to 750 ~ ~ 770 degrees; insulation must be time; in the cold cooling to 600 degrees below air cooling.

ㄈâ”慊鸺 Press 慊鸾橹.1) Harden color (experience) White is the hardest and brittle; Yellow is hard and tough; Blue is soft and tough.
.2) quenching medium A water: usually the temperature does not exceed 40 degrees; no oil; Panyu and other impurities. B salt and alkali aqueous solution: add 5-10% salt or alkali in water. Salt solution cooling rate is water Ten times; high hardness and uniformity; but the arrangement of stress is large; there is a certain rust effect. The temperature is less than 60 degrees. The alkali solution (caustic aqueous solution) is highly corrosive; the customary scale is small. C oil: contains engine oil; spindle oil; Oil; diesel, etc. can reduce deformation and cracking. Not applicable to carbon steel. Oil temperature: 60 ~ ~ 80 degrees; the highest does not exceed 100 ~ 120 degrees.
The mold steel is used for low temperature tempering. The temperature is 150-250 degrees. Under the premise of insisting on high hardness and high wear resistance; reducing internal stress and brittleness; avoiding cracking or premature damage during use. Hardness HRC: 58 ~ ~ 64.
