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%.

Introduction of GB/T 11251 42CrMo - steel-plate-sheet

Introduction of GB/T 11251 42CrMo ultra high strength steel plate has high creep strength and rupture strength at high temperature. The surface hardening after quenching and tempering is usually used as a heat treatment scheme. As a plastic mould steel, 42CrMo steel has excellent workability and good mechanical properties. Shaft Machining_Technology, Material, Tolerance For the shafts that require greater force, shaft size and weight are limited, and there are certain special requirements, alloy steel can be used, commonly used 40Cr, 40MnB, 40CrNi and so on. The material of the shaft is mainly carbon steel and alloy steel.
