Product Description
GB/T 3077 30CRMO ALLOY STEEL PLATE
GB/T 3077 30CRMO alloy steel plate has high strength and toughness, high hardenability, and the critical hardenability diameter in oil is 15~70mm; The thermal strength of steel is also good, and it has sufficient high temperature strength below 500℃, but its hardenability at 550℃ The intensity drops significantly.
When the alloy element is at the lower limit, the welding is quite good, but when it is close to the upper limit, the weldability is medium, and it needs to be preheated to above 175℃ before welding. GB/T 3077 30CRMO alloy steel plate has good machinability and medium plasticity during cold deformation; heat treatment at 300~350℃ The range has the first type of temper brittleness; there is a tendency to form white spots.
