1.Round steel
2.Diameter: 250mm-800mm
3.Length: 6M
4.Forging materials
5.Quality,GB2 defectoscopy
Type of steel, because of its suitable hardenability, the appropriate metal after heat treatment, microstructure is homogeneous sorbite, bainite or fine pearlite, which has a high tensile strength and yield strength ratio (usually about 0.85), higher toughness and fatigue strength, and lower the ductile - brittle transition temperature, can be used to make cross-section of a larger size machine parts.
