30CrMnSiA steel plate is a grade of alloy structural steel stipulated by the Chinese national standard. Unified digital code: A24302. 30CrMnSiA steel plate is a high-strength quenched and tempered structural steel commonly used in machinery manufacturing. It has high strength and toughness, and medium cold deformation plasticity. 30CrMnSiA steel plate can be used to make connecting rods, bolts, transmission shafts and Spindles and other parts of machine tools. In addition, it is also widely used in aircraft.
Advantages of 30CrMnSiA steel plate material: The reason why 30CrMnSiA steel plate is widely used is its superior performance, which is determined by its own chemical composition; in addition, through appropriate heat treatment process, the superior properties of 30CrMnSiA steel plate can be fully realized play out.
The properties of 30CrllnSiA steel plate, from the iron-carbon alloy phase diagram, 30CrMnSiA steel plate belongs to hypoeutectoid steel, and the structure after slow cooling to room temperature is ferrite + pearlite; from the perspective of steel classification, 30CrMnSiA steel belongs to low hardenability It is quenched and tempered steel with low hardenability.
It can be hardened by medium 25mm during oil quenching. It has high strength, good plasticity and toughness, that is, it has good comprehensive mechanical properties. The 30CrMnSiA steel plate is delivered in a heat-treated (normalized, annealed or high-temperature tempered) or no heat-treated state, basically in a normalized delivery state.
