Forging heat treatment
Tempering quenching and high temperature tempering double heat treatment, the aim is to make the work with good mechanical properties. Tempering: hardening tempering heat treatment called tempering. For tempering tempering is defined in the 500-650 between. Properties of quenched and tempered steel, materials are adjusted to a large extent, the strength, ductility and toughness are better, with good mechanical properties. After quenching and tempering are tempered sorbite. Tempered sorbite (tempered sorbite) is in tempering of martensite formation, under optical microscope magnification 500~600 times to tell them apart, the carbides in ferrite Matrix distributed (including cementite) particle composite. It is a tempering of martensite organizations, is a mixture of ferrite and carbide granular. Ferrite has been carbon-supersaturation, carbides are stable carbides. Room temperature is a balanced organization.
