GB/T 11251 20Cr hot rolled structure steel plates can also be used as low-carbon steel for martensitic quenching, which further increases yield strength and tensile

GB/T 11251 20Cr hot rolled structure steel plates - Bebon

GB/T 11251 20Cr hot rolled structure steel plates ,GB/T 11251 20Cr hot rolled structure steel plates are widely used to manufacture carburized parts (oil quenching) that have high requirements for core strength, bearing surface wear, section below 30mm, shape is complex and load is small. For example:machine transmission gear, gear shaft, cam, worm, piston pin, GB/T 11251 30CrMnSiA alloy steel plates - BEBON steelGB/T 11251 30CrMnSiA alloy steel plates are medium carbon tempered steel with high strength and poor welding performance. After quenching and tempering, 30CrMnSiA alloy steel plates have high strength and toughness and good hardenability. GB/T 11251 30CrMnSiA alloy steel plates chemical composition:

GB/T 11251 30CrMnSiA hot rolled structure steel plates

GB/T 11251 30CrMnSiA hot rolled structure steel plates are medium carbon tempered steel with high strength and poor welding performance. After quenching and tempering, 30CrMnSiA alloy steel plates have high strength and toughness and good hardenability. GB/T 11251 30CrMnSiA hot rolled structure steel plates chemical composition: GB/T 11251 35CrMnSiA hot rolled structure steel plates But at the same time, its corrosion resistance and oxidation resistance is low. Therefore, GB/T 11251 35CrMnSiA hot rolled structure steel plates are usually used after low temperature tempering or equal temperature quenching. GB/T 11251 35CrMnSiA hot rolled structure steel plates chemical composition:

GB/T 11251 40Cr hot rolled structure steel plates - Bebon

The hardenability of the steel is good. GB/T 11251 40Cr hot rolled structure steel plate is also suitable for cyanidation and high frequency quenching in addition to quenching and tempering treatment. The cutting performance is better when the hardness is from HB174 to 229, the relative machinability is 60%.

    On-line Quenched and Self-Tempered High Strength Steels

    Quenched and tempered carbon steel for machine structural use (e.g., S45C class) had been applied for-merly as a steel material for construction machinery parts and other applications with similar requirements. Later, application of V-added quenched and tempered free steel was expanded with the aim of omitting the quenching and tempering process. gbt 11251 15cra steel mill(PDF) Steel slag in China Treatment,recycling,and .
