 45 ා precision bright tube product display
  45# Precision bright tube The carbon content of the material is about 45 / 10000, which belongs to medium carbon steel and has good cutting performance. The mechanical property is good, but the welding property is poor. It is cheap. After quenching and tempering (or normalizing), it can obtain better cutting performance, higher strength and toughness and other comprehensive mechanical properties. After quenching, the surface hardness can reach 45-52hrc.
1.45 standard for precision bright tube:
    GB / t8162-2008 seamless steel tubes for structures.
two 45 mm precision bright tube Chemical composition:
    C:0.42~0.50%、 Si:0.17~0.37%、 Mn:0.50~0.80%、 P: ≤0.040%、 S: ≤0.045%、 Cr:≤0.25%、 Ni:≤0.25% Cu:≤0.25%

four 45 mm precision bright tube Product application:
    45 ා precision bright tube is widely used in mechanical manufacturing. The mechanical properties of this steel are very good. However, it is a kind of medium carbon steel, and its quenching performance is not good. 45 steel can be hardened to hrc42 ~ 46. Therefore, if the surface hardness is needed and the superior mechanical properties of 45 steel are expected to be exerted, the surface hardness of 45 steel can be obtained by carburizing and quenching the surface of 45 steel.
